Reduced energy consumptions with the new hydraulic ME presses
The new Mecolpress ME hydraulic presses grant reduced energy consumptions.
How did we get to achieve this goal?
Mecolpress has been working with its customers for more than 50 years providing the best forging technologies that allow to maximize the quality of the products and the related productivity.
The forging process improvement needs do not always seem to proceed in the same direction:
- the energy consumption reduction requires the reduction of the installed power;
- the high productivity and the raw material reduction require increasing installed powers.
Our customers and partners are dealing with this conflict and are wondering how to come out as winners.
“Which is the most abundant existing source of energy? the least polluting, least expensive, most immediately available one: that is, energy saving …”
Piero Angela
What does Mecolpress propose to grant in the same page reduced energy consumptions and high productivity?
Mecolpress is not afraid of challenges, indeed it knows that these represent an opportunity to grow and improve.
Thanks to the continuous and accurate control system, Mecolpress presses determine and memorize the process parameters at every fraction of a second, i.e. the minimum force and speed requirements to obtain a certain product with the best characteristics. Under these values it is not possible to obtain an acceptable product.
Our long experience has allowed us to evaluate numerous forging cases, from small connectors of ½” up to large valves/water meters of more than 2”, in standard and lead-free brass grades.
To reduce power when it is not needed and to maximize it when it is needed! This is the secret.
The forging process control system
The press control system learns (ADAPTIVE CYCLE) the trend of the forging cycle and regulates the pressure and the flow of the oil (REGENERATIVE CYCLE) in order to get as close as possible to the minimum forging force. A reasonable safety margin is maintained in order to compensate for eventual external parameters variation (billet temperature, material quality, dimensional tolerances, …).
During the forging cycle Mecolpress press will have three phases: power reduction, transition, maximum power.
We monitored the flash-free forging process of the body of a 1 1/4″ ball valve with a productivity of 12 pieces per minute, therefore 720 pieces per hour.
Thanks to the ADAPTIVE-REGENERATIVE cycle the energy consumption is reduced by 50%, reaching an average consumption of 45kWh.
But let’s not forget the other advantages acquired:
- production capacity more than doubled compared to the traditional cycle,
- high repeatability of the piece quality (cp>2),
- constant compliance (cpk>1.33) with very tight dimensional tolerances (± 0.1),
- minimized material consumption thanks to over 6% flash-free forging,
- improved workability thanks to a more uniform internal conformation,
- increased product quality thanks to the elimination of internal defects.
SEO/320: THE MECHANICAL PRESS ADDRESSED TO THE MODERN FORGING
The new continuous and discontinuous cycle mechanical press
Mecolpress is proud to introduce the new model of continuous/discontinuous cycle mechanical press for hot forging, size 320 tons.
This press is designed to improve the features of all the previous machines in the size range from 200 to 360 tons. Finally just one single press will be able to guarantee the performances of the historical SEO/27 CVE-CS or SEO/36 CVE-CS presses, and it will be the new mechanical SEO/320 press, indeed!
The experience acquired in more than 50 years of activity brought us to analyze every day the forging needs of many worldwide Customers. The main topic that emerges is that the greatest force capacities are needed to deform new materials, high alloys\without lead that are considerably more high-strength.
The result is a totally innovative press that includes all the improvements that Mecolpress applied over the recent years.
SEO/320 press was born to satisfy all the new productive needs demanded by the ongoing changes in the world of “modern forging”.
Recurring problems for a forger
If you are a forge manager or an owner of a forging factory, it surely happened to you that, to satisfy your Customers request, you brought your presses to the higher limit of the performances. Consequently one of the following situations will surely happened at least one time::
- breakage of the gears, and in particular of the teeth;
- breakage of the transmission shafts;
- maintenance on bearings and clutches….
Forcing you to unexpected machine stops, with all the related inconveniences\additional costs!
Solutions proposed by Mecolpress
Machine downtimes cannot totally disappear. We must remember that we are talking about mechanical presses that forge metals at very high temperatures and that can be subjected to overloads! But these can be drastically reduced.
”Why often we say that years ago the machines did not break down?”
The answer is easy! They were sized and studied specifically for the productive needs of that time that do not coincide with the modern ones any longer!
Mecolpress answer to the new required performances in the forging operations is the new SEO/320 press that is what each forger needs today!
Technical characteristics of mechanical press SEO/320
- The machine has a monolithic structure in welded steel in order to ensure the maximum stability and duration over the year.
- The gears have a total innovative structure and extremely simplified that does not consist only in the dimensions increase, as you might think, but it consist of a series of improvements that allow the machine to work to the maximum performances without any breakage risk.
- The cushion was simplified, with the removal of the manual adjustments and of the mechanical parts generally subjected to wear.
- The flywheel was developed to guarantee enough deformation energy even at low turns. This particular characteristic is very appreciated by who has to forge the material requiring low deformation speeds.
- We have paid close attention to the ergonomic aspects: the operator can set up the tooling of the machine very quickly and without excessive efforts. Therefore you will find the equipment without tight spaces with wide visibility and, above all, safe and reliable.
We summarize in the following table the main technical characteristics of the new SEO/320:
An opportunity for the forgers
Mecolpress offers to every potential customer the possibility to inspect at least one version for each machine model at the production site based in Flero (Brescia). As a matter of fact, the main versions of the most requested models are always in production.
This results in an important advantage for you Customer because we are offering:
- the opportunity to see/experience the new machines with the support of our specialized personnel at your disposal to clarify any doubts or curiosities;
- A very competitive delivery time In case of purchase!

Smart Brass Forging
By Danilo Fagnani
MECOLPRESS started their activities in Brescia (Italy) more than 50 years ago, in 1969, providing solutions for the hot brass forging industry. MECOLPRESS then widened its portfolio including hot forging steel, aluminium, titanium, and special alloy applications. MECOLPRESS is now offering the most modern technologies available for mechanical (HEAVY family), hydraulic (ME Family) and screw driven (TDS, FPN family) presses.
The region of Brescia, located East of Milan, is generally considered the cradle of brass production, at least 20% of the total world production is firmly located here. The Brescia region is still able to compete with Chinese brass manufacturers (35% of the brass total world production) even if the production costs are not comparable in terms of manpower, energy and etc… The secret of this success is the know-how of the full brass production chain, industrially started from the 19th century, from melting process passing through forging then achieving the final product completion. MECOLPRESS was born and built in this interesting and dynamic environment, participating and contributing to solve the main challenges of brass producers (Smart Brass Forging).
These challenges are cyclically recurring in the market, and they can be summarized as follows:
- raw materials availability and costs;
- high variability in the market for parts from the peaks of high demand to small lots with frequent parts changeovers;
- difficulties to find the necessary manpower, from highly skilled operators, to maintenance technicians, to standard operations workers;
- availability to grant the best products quality reducing the non- compliant ones;
- reduction of the energy consumption approaching the green economy
MECOLPRESS is supplying to the market the most powerful hydraulic presses (ME family) offering horizontal\vertical coring performances achieving:
- flash-less forging;
- reduced part material thicknesses;
- deeper and deeper punch coring
These features drive achieving parts with less weight and avoiding any further downstream process as trimming. ME hydraulic presses family (more than 60 units supplied from 2010) has standard sizes:
- 100 to 500t as die closure force
- 30 to 350t of punch coring force
The coring punches have independent movement guiding and optimizing the flow of material inside the die’s cavity. The punches forces, speeds, displacement sequences can be flexibly implemented in the HMI operator panel depending by the products to be forged (Smart Brass Forging). One of the four horizontal punches can be orientable (without losing coring force!) with the variable angle from from 0 to 45° allowing sloping coring for the parts.
The ME family hydraulic presses grant production performances that, depending by the equipment size, can reach up to 30 cycles per minute and they allow to forge multiple parts per stroke, throughout of some thousands of parts per hour is easily achievable. This will allow to complete productions lots is shortest time even if they are relevant in the number of parts to be reached. If the market conditions are changing and the market moves to lower number of parts per lot with frequent shifting between the products, the quick dies changing system will allow to dramatically reduce the down time. The fully automatic tools locking\unlocking and the servo-moved supporting arms allow one operator to accomplish the change in the quickest time (about 15-20min), in the complete safety conditions and without the help of any tools (Smart Brass Forging).
Mecolpress ME Next Generation series hydraulic press hot forging EG coring tool
The MECOLPRESS policy to reserve relevant stock of spare parts for all the presses that have been supplied is a key point to avoid unwanted down time in case of maintenance of the equipment.
Mecolpress ME Next Generation series hydraulic press outstanding parts weight reduction
MECOLPRESS is developing all of the control software for the presses: CALIPSO (Smart Brass Forging). This user interface is based on a touch screen model, it is very easy and intuitive, and it has been developed in several different languages; it allows any end user operator to work with continuity on the press and it does not require any particular skills or knowledge. Many functions have been simplified as input parameter requests to reduce the human factor effect in the press working conditions. CALIPSO defines and controls automatically all the ME family presses operations, from raw material loading up to forged parts unloading. The main parameters of each product receipt are saved in the internal memory, and can be easily retrieved for future production and transferred to customer MES\MRP. The press has an Ethernet OPC-UA connection module that grants this function as well the remote teleservice assistance by the MECOLPRESS technicians.
The MECOLPRESS R&D department is able to define the optimized process parameters and/or the best die geometry through FEA software which allows them to analyze both material flow and forging force. This on-demand service is appreciated by customers who are searching for a reliable supplier.
ME hydraulic presses can be paired with all types of furnaces: billets, bars, natural gas, electric induction, keeping in mind that the reliability on the heating temperature, the billet weight tolerance and the material metallurgical microstructure properties are key parameters to grant effective flash-less process success.
High production capacity, flexibility to switch from one product to another and high equipment reliability vanish if the forging process is not under full control. CALIPSO software is leading the game supporting the customers to control, with minimal effort. The forging forces, punches displacement parameters and sequencies, billets temperature, and so on can be monitored in the maximum\ average values or continuously during the working cycle. The desired thresholds can be set in the system to monitor the trends of the parameters and if any mismatch is found, the parts can be diverted automatically to the dedicated collecting box for further checking.
MECOLPRESS is fully committed to be an effective part of the green transition of the industry, reducing the energy consumption, pollution emission, and media consumption. This application shall not decrease or compromise the outstanding powerful performances of the ME family presses. CALIPSO and in-house engineering are the main characters of this target:
- hydraulic auto-adaptive regenerative function circuits;
- ECO mode for working pressure optimization;
- actuators optimized geometry;
- flexible set up of the operating pressure;
- AC frequency converters\variable flow hydraulic pumps;
- CALIPSO software that learns from experience optimizes the working parameters without relevant operator required intervention (Smart Brass Forging)
Mecolpress ME Next Generation series hydraulic press main view
These points collaborate to reduce the energetic consumption up to 50% in comparison with standard technology presses.
The dies lubrication system, very important in the flash-less forging, is using innovative pipe to pipe technology supplying alternative air and oil flows just with the needed quantities. All the dies lubrication parameters are set into the control software and up to 30 points can be reached; they can be integrated into the dies or with external nozzles. The proper pumps are installed on the machine bottom to collect all the remaining quantity of oil avoiding any overflow. The press lubrication is selective and only the components active are reached by the media, proper collecting box avoid leaking. No more waste of fluids!

HYDRAULIC PRESS, Mecolpress leap into a new eco-green modality
Main features of the new ME eco-green Hydraulic Press
Mecolpress S.p.a. is glad to introduce the new improved features of ME family hydraulic presses, born from the need to offer to the Customers a more flexible and performing machine in terms of product quality and energetic consumptions.
We are currently proposing the family of ME presses having the die closure force that is in the range from 100 to 500 tons (as standard equipment) and with a minimum side punches force of 30 tons that can achieve up to 350 tons. Each of these last ones has completely independent operation, adjustable speed and set-able movement phases (forward-stop-backward); depending by the type of part to be forged , the hydraulic closure cylinder allows to apply the necessary forging force also before the dies contact.
The new presses can be fed by one anthropomorphic robot for the billets loading and one synchronized unloading arm for the forged products that eliminate the set up difficulties of the traditional past technologies; regarding the fumes suction, after a careful analysis of the actual state of the art, we have implemented and optimized the system making it more functional and effective.
The fume suction hood collects the emission very close to the sourcing point decreasing any possible spread into the press cabin, granting to the operators the best inside view of the process and reducing the oil collection and its possible overflow.
In this regard, the machines of the new series are integrated with the walkable grids that surround the press and prevents the eventual drip on the floor of the working area.
The hydraulic presses can be supplied customized with optional equipment according to the production needs.
For example, one of the punches can be oriented with the coring angle that is different from the classic 90° configuration , allowing in this way the realization of particularly complex shapes, like y-joint or filter body.
Other possible configurations are of new ME eco-green Hydraulic Press are:
- the addition of a fifth vertical punch acting from under the die,
- the loading of one or two billets at the same time up to a maximum of four,
- the addition of a dies-holder arm lightening the machine tooling process,
- the addition of a quick dies changing system with hydraulic locking,
- the addition of an induction dies heating system which the machine is particularly compatible with,
- fire extinguishing system integrable with the machine.
Moreover the main innovation is related to the energy saving achievements if compared to the previous series.
From 2022 all the ME presses can minimize autonomously the energy amount that is needed to produce the desired forged part: the press learns automatically the optimal pressure to be addressed to each forging punch: ECO cycle (settable from the control panel). Furthermore, during the movement of each forging punch, Calipso control software optimizes the time in which it is necessary to switch to the maximum achievable pressure (regenerative self-adapting cycle function): all the press parameters will be consequently harmonized according to this requirement.
This behavior represents the key economic and competitive advantage for the press user that can save up to 50% of the total installed energy without losing or reducing the punches force and can optimize the forging process parameters in order to minimize the energetic consumptions. To do this the operator direct intervention is no longer necessary. The operator is not required to have a long term experience or particular skills : he will simply have to activate the ECO cycle from the control panel, ME press will care of the rest!
he will simply have to activate the ECO cycle from the control panel, ME press will care of the rest!

The technology and the strategies to win the challenge
Click on image for the English version of the article:
The change is a constant in our lives and for Mecolpress, for more than 50 years, it is seen as an opportunity.
That’s how that the best projects and products are born and developed.
Shape the Future!
Are you doubtful between mechanical press and hydraulic press?
Are you doubtful about the press to choose? Mechanical press or hydraulic press?
Ask to Mecolpress, you will have no more hesitations!
You have just got a new commission and you need a new press for hot forging. Are you sure that you can identify the press that best suits your needs?
Typical request
It often happens that a Customer, or potential one, comes to us with the part he desires to forge. Usually it’s about complex situations, very far from standard applications. That’s exactly why the Customer asks for our help and support.
If the Customer is not a newcomer in the forging world, he usually arrives in Mecolpress with clear and straight idea about the type of press he wants. But very often it happens that he will change his view after having the possibility to get in contact with our forging know-how!
You ask for a mechanical press but you need an hydraulic one!
For example, some weeks ago two different customers came to visit us bringing some sampling to be forged. They were sure to ask a quotation for a mechanical press, they realized instead that the right machine for their situation was a hydraulic one!
Both our customers had the chance to test new dies, only 4 hours were needed for the preparation and installation of the dies and to run some tests. Even though the furnace was not the best one for their kind of production, because it’s a furnace that Mecolpress uses for testing, the machine gave a flash-free part in only 4 hours, with a saving of about 30% of material and with a quality definitely superior than the one they could achieve using a mechanical press.
Moreover, it is important to take into consideration the limits of the mechanical press:
- Since the part is not balanced, the mechanical press should use all its possible force to forge it.
- Working in this way the risk to run into damages or machine breakdown becomes greater.
On the contrary, The ME hydraulic press can forge the part better. The forged parts which required more force used however less than 200 tons on a punch, therefore it consists of a forces distribution that is totally different compared to the traditional mechanical press.
Often the customer is skeptical towards the hydraulic press, but just because he is not familiar with it!
Find out more about the hydraulic presses
The hydraulic presses patented by Mecolpress are suitable for the hot forging of standard parts or special parts in brass and aluminum. The dies closure force is higher than the one of the traditional mechanical presses and the independent and controlled movements of the ram and of the extruders allow to hot forge also complex parts without flash.
These are oleodynamic presses provided with coring tools combinable till to a maximum of 5 punches (4 horizontal and one vertical) suitable for the hot forging of brass, aluminum, copper and other materials.
Compared to the traditional mechanical presses these presses have different advantages, including:
- Reduced vibrations and noises.
- No foundations are required.
- Higher flexibility: there are no mechanical connections between tooling and ram; this implicates that you can decide speed, force, position and movement sequence for each punch independently. The result is the possibility to decide how to let the material flow, this helps the part production with a better quality level.
- Ease of tooling: easy access to the forging area and automatic adjustment of punches strokes from the panel that cancels the mechanical adjustment on the spines (for example insertion of spacer).
- The press is easy and intuitive to be used even without a great experience in the forging field. Together with the machine a lifelong service via teleservice and phone assistance is provided.
Some practical examples about the choice for a hydraulic press.
- Hydraulic press ME150: this is a quite small machine and often we suggest it to who has no experience in the hot forging field.
- Hydraulic press ME 250: let’s get serious!
Example: are you undecided if you want to buy a 400t mechanical press or a ME250 hydraulic press?
If you have small and easily to force parts to be produced in huge quantities and in series maybe the choice of a mechanical press is the most suitable, but if you have a part that is lightly more complicated, probably you need an hydraulic one. In this case, we are sure that a test here in Mecolpress will remove any doubt!
- Hydraulic press ME from 450tons onwards: This press is more efficient, more cost-effective, it allows to save material, to increase the productivity, it is more convenient, more silent, no foundation pit is required and despite of what our competitors affirm, the energy consumption is not high. In fact, this consideration comes from the fact that just the installed power is taken into consideration.
Did you carry out a forging simulation and forging tests?
In order to choose the right press it is surely helpful to carry out a forging simulation, our technical office can support the customer during the process for choosing the machine with a software analysis of material flow, in order to carry out a sort of “virtual pre-acceptance” of the plant.
Once that the forging simulation is successfully over, then the next step is a real test in our factory. Indeed we have available machines devoted for the forging tests, this is a very important aspect for the customer that often gives him the possibility to invest in a more aware and motivated way. Touching the forged part doesn’t leave no room for doubt!
Being able to satisfy and fully understand the customer needs, to demonstrate and propose our most suitable solutions with concrete tests thanks to the machines and toolings we have available in Mecolpress for the forging tests is for us matter of pride.
Biography of our hot forging blog
At the beginning of 2017 Mecolpress decided to start a blog entirely devoted to the hot forging world.
We set for it 2 goals:
- Being a reference point for hot forging companies, above all if these are first-time forgers.
- Supporting the companies having a long hot forging experience but that want to optimize their process, to better use their presses and to find answers to the necessities they meet step by step.
We have realized, doing some internet researches that it is very difficult to gather information regarding the hot forging world.
On Google you can find anything, but you will barely find suggestions or detailed deepening on hot forging!
Frequently we happen to be contacted by beginner hot forging companies, or companies having inexpert or not particularly qualified personnel (for example you can read this article) and all of these want to have further information.
We are aware that it is not possible to become expert forgers or to learn a job from Google but it is equally true that in 2020 I have to find answers on the internet to my necessities and some deepening on the topic.
Who are we?
Mecolpress is a company specialized in the production and installation of hot forging presses for brass, aluminum, copper, titanium, steel and other alloys.
Mecolpress was established in 1969, therefore we have a long forging experience and knowledge.
In our production workshop we have persons extremely expert in brass hot forging, and recently we have inserted in our staff also a steel “technologist”, we have available a mechanic and electronic technical office completely internal and a highly appreciated customer-care service.
To date we have developed and installed more than 1.950 presses at more than 400 customers all over the world, used for the forging of brass, aluminum, copper, titanium and steel.
One of the features that our customers usually appreciate most is the after sales service: the great and guaranteed material availability is added to the expertise and solid knowledge of the machines. The efficient feedback of Mecolpress lies in the largeness of the areas dedicated to the storage of parts that can be requested by the customers (we have 2 devoted warehouses) and in the investments decided exactly in favour of the “warehouse”.
Why writing a blog regarding hot forging?
At this point we said “why not sharing part of our skills online? For example, with a company from South Africa that is wondering if it’s worth it to convert his production in a hot forging system?”
“And in addition, could all the expert forgers (Mecolpress customer or not) be interested to understand if there are improvements to apply to their production? The world has changed and even fields such as the hot forging one may seem as more “static” but, as a matter of fact, they are not. If you don’t stay up to date you will lose important commissions and the quality of your work won’t evolve!
Which kind of answers will you find on this blog?
With our blog we offer ideas and tips to improve each forging process. To manage the machines and the forging lines in the best way in order to obtain the best productivity, more flexibility and less maintenance.
The topics that according to us are easier to speak on are the technical ones, thanks to the experience acquired in 50 years of activity and to our numbers, but we try to maintain a character that can be easily understood also to the less experienced companies, remaining at disposal for further in-depth detailed explanation.
In the “Case Study” category you will find for example:
- How we could help a German customer of ours to win successfully a challenge, to forge a very complex set of parts that he didn’t dare to accept as an order.
- Is it possible to reduce the gate valves costs by forging without flash? It is possible by means of ME hydraulic presses.
- Is your screw press driving you crazy? You could have disregarded what for you is just a detail, but our experience taught us that it can make the difference!
We propose solutions to problems caused by a not optimal usage of the presses or screw presses, by the inexperience; these are requests that we collect from our after-sales department. We give voice to necessities that also for expertised hot forging companies sometime can appear as complex.
A challenge we can win for our customer means for us a great satisfaction!
HOT FORGING PRESSES INTERVIEW WITH MECOLPRESS
Company manufacturing hot forging presses.
We report an interview of the digital magazine Easy Engineering of 28 April 2020.
Established in 1969, MECOLPRESS was founded as a manufacturing company of mechanical presses for brass components hot forging. Up to today, Mecolpress has developed and installed more than 1.950 presses, at over 400 customers all around the world, used for forging brass, aluminum, copper, titanium, steel. The current production site in Flero, in the highly productive area of Brescia, takes up a 30.000 square meters surface, 10.400 of them are covered and employees 55 people, reaching a turnover in 2018 of 11.5 million Euro.
In 2019, in occasion of EMO exhibition in Hannover, Mecolpress officially presented the new series of continuous and discontinuous cycle eccentric presses, the HEAVY series.
Easy Engineering: What are the main areas of activity of the company?
MECOLPRESS: At the beginning all efforts were concentrated on brass hot forging field; in the time, also through the acquisition of the historical brands Osterwalder and Dellavia in the screw presses section, the variety of machines that we design and produce is now so wide and complete to satisfy the most different requirements of the customers: for each specific material, shape and quantity to be forged, we are in the position to offer the most suitable solution.
Mecolpress is today the only company among the manufacturers of presses for the hot forging of brass, aluminum steel, copper, titanium, with a so complete production program.
Our present production program consists of:
- TDS: direct drive with electrical servomotor;
- Dellavia and Osterwalder: Traditional disc friction.
PG Knuckle joint presses
for calibration and coining of parts.
Presse Meccaniche Eccentriche
- SOV and SEO/F: for the vertical hot forging;
- SEO and HEAVY: for forging with horizontal cores, in single or continuous cycle.
for forging brass and aluminum parts without flash.
- PO: single station;
- S: multiple station, rotary table with hydraulic motor;
- E: multiple station, rotary table with electric motor.
In addition, Mecolpress is particularly active in after-sales service. The heart and pride of Mecolpress is its large spare parts warehouse, which is able to supply accessories or spare parts for machines produced fifty years ago. For this reason, in addition to the sale of machinery, there is a wide activity related to the service and supply of accessories (such as tools, arms, spare parts, etc..).
E.E: What’s the news for 2020 about new products?
MECOLPRESS: At the end of 2019 Mecolpress presented at EMO fair in Havvore a brand-new series of eccentric presses, named HEAVY, which defines a new standard for the hot forging of brass.
A machine concept that offer highest durability and reliability together with an innovative software system that allows the maximum control on the process and the a very easy operation.
E.E: What are the ranges of traded products?
MECOLPRESS: As a manufacturer with an own wide range of products, the additional equipment that we simply trade is limited to ancillary machines, to offer complete forging lines (delivering a finished part from the input of a raw material bar) to those customer that prefer to have a turn-key plant from one source.
Typical traded machines are: billets heating furnaces, forging dies, sand blasting machines.
E.E: At what stage is the market where you are currently active?
MECOLPRESS: Since our machines are dedicated to a very wide panorama of applications (from house building to automotive, from gas control to biomedical) there are always new developments in these sectors.
This is for us very stimulating because we are constantly involved in the design of new solution, to support our customers with the most suitable equipment to manufacture parts that are chancing in the shapes, in the alloys and in the technical requirements.
E.E: What can you tell us about market trends?
MECOLPRESS: In the past our customers were mainly subcontractors, producing many different kinds of parts for the most differentiated OEMs. We see now more and more companies that are interested in bringing back into their own activity the hot forging process, to have full control over the entire production line. And also, the subcontractors that still exists, are increasing in size, in capability, and in specialization: they are requested to be much more accurate, reliable, more flexible and fast in changing production and technologies.
For these reasons, the machines that both our customer types (the subcontractors and the OEMs) need, are machines that can easily switch from one application to the next, and that can record and control really in depth every aspect of the production process. The user is therefore becoming more an engineer, that study and program the process in advance and then let the machine run autonomously, instead of an operator that has to stay full time at the machine, checking and adjusting the settings.
E.E: What are the most innovative products marketed?
MECOLPRESS: As above indicated, one of the most innovative products that we offer today is the new range of Heavy presses.
In parallel to this, we are widening the offer for the ME hydraulic presses which are designed to forge net shape parts. These machines are extremely versatile, can communicate in two directions with the company ERP software to exchange production data, recipes, preventive maintenance information. And are also able to automatically detect a non-conforming product and separate it from the good ones. This makes the ME forging presses a fully automatic system, that does not require operators to work but also does not need regular presence of quality control staff to check periodically the output.
E.E: What estimations do you have for 2020?
MECOLPRESS: At the end of 2019 we planned a very aggressive budget of sales for the 2020, and supported it with several activities and strategies, from the participation to many international shows, to the production of machines for stock, to grant to our customer very fast deliveries.
Unfortunately, due to the Covid-19 virus spreading, many commercial activities had to be reprogrammed or postponed. We are now investigating the world markets to assess what will be the customers’ propensity to invest for the remaining months of this year. We are very optimistic that we will in any case be able to reach most of our targets also thank to the availability of machines in our workshop, which is allowing us to complete deliveries in this year of machines ordered in the second and third quarter.
THE PRESS AUTOMATICALLY SEPARATES THE FORGED PARTS: GOOD IN ONE BOX, BAD IN ANOTHER!
Differentiated unloading of the forged pieces
The press automatically separates the forged parts and divide them into different boxes. The press has become intelligent!
The differentiated unloading of the forged parts is an interesting function that Mecolpress provides by default on all hydraulic presses, but it can also be added as an option on eccentric mechanical presses.
Hot forging for higher quality of forged parts
The metal hot forging differs from the cold one because it allows you to obtain high quality pieces through an important deformation of the starting material. By working brass, copper, titanium, steel and aluminium by means of hot forging presses, in fact, it is possible to produce particular shapes, even with complex geometries.
The metal hot forging therefore allows to obtain parts that are more resistant than those obtained through other production processes.
In particular, metal hot forging can increase the strength and resistance of the products. For these reasons, the production of hot forged pieces guarantees specific advantages in their mechanical characteristics compared to those produced with other technologies such as casting or mechanical machining with chip removal.
The hot forging, compared to the casting processes, allows to obtain mechanical characteristics and surface appearance of superior quality. We at Mecolpress know it well, so much that we have made “Technology of Shape” our motto.
The piece produced must therefore be perfect, its quality must be certified. For this reason, Mecolpress has designed a system that allows the press automatically separates the perfect forged parts from those to be evaluated as they may not be such.
Why is it so important that the press separates the perfect forged parts from those to be evaluated?
From the automotive sector, the Lean production method teach us:
- Companies can be competitive on small production batches (producing only what is necessary) instead of manufacturing high quantities at low prices, with the risk of keeping high stock levels, are rewarded with success.
- The second must of the “Lean” work methodology is the zeroing of the waste and dispersions, or in other words, of the useless productions because of defected parts.
One of the most recurring needs in our customers is to have an ever more intense control of the forging process: the machine must be able to control as many parameters as possible important for the forging process, record them to make statistical predictions on the deviation from the optimal production, carry out checks.
Mecolpress offers a series of forging presses that fully meet the needs described above: the ME hydraulic series.
The hydraulic presses can control numerous process parameters and on these manage the logic for rejects or collect the measured values for statistical analysis. For example, they can control:
- the temperature of the billets to be loaded,
- the coring punches penetration time,
- the punches real penetration force,
- the final position reached by each punch.
Here you can learn more about the most important process parameters that hydraulic presses are able to evaluate.
The machines of the ME series have the credentials to be competitive in a modern and controlled forging field; they operate at their best on medium / small batches, thanks to their flexibility.
In this video we show how our hydraulic presses perform the differentiated unloading of the forged parts:
The pieces that do not fully comply with the process parameters set by the operator and analysed by our powerful Calipso software to control the forging process, are unloaded in a separate bin.
For the customer this operation translates into an important saving method:
- Less waste of time,
- Less material / pieces to be discarded,
- Be sure that the forged piece complies with the required characteristics,
- Get perfect shapes.
Hot forging presses: Mecolpress technology
Application sectors of the hot forging
Mecolpress offers a wide range of hot forging presses, able to satisfy the necessities of the individual customers and that allow to forge parts for different industrial sectors. Our presses can be used for the production of:
- Thermohydraulic pieces;
- Mechanical parts in aluminum, copper and brass, used in the railway and automotive sector;
- Clothing parts such as buckles and zippers;
- Stainless, titanium and steel screws for applications in any sectors, from the aeronautics to the railway.
The bio-medical one represents a very particular sector, indeed, with our presses it is possible to forge parts for titanium prothesis. The pieces produced by Mecolpress machines address also to the sector of the production and distribution of high-pressure gas, for the medical, automotive and industrial sector.
Not only mechanical presses, here the Mecolpress proposals
A functional commitment that all these sectors have in common undoubtedly is the precision during the material forging, but also from a design point of view Mecolpress reaches through the research for the perfect shapes a remarkable significance. This is exactly why we propose different typologies of presses, including hydraulic presses, mechanical presses, clutch and electrical servomotor screw press, knuckle joint press and trimming machine, that are able to hot forge several materials, including brass, steel, aluminum, titanium and copper.
The support of our Research & Development department
Our range of presses, so differentiated, is due to the work of our Research and Development department, a team that has revealed itself as very precious, not only for Mecolpress Company but also for our customers, because it allows them to achieve several goals. First of all, our staff helps the forger to identify the systems to optimize the production through hot forging of parts in such a way that the further machining will not be needed. Moreover, our specialists can evaluate what could be the productive implications in the usage of different metals alloys and help to identify them. The Research & Development department offers support also for adapting the complete hot forging line composition according to the customer’s needs, to his industrial sector and to the habits of the specific Country.
So, our company is at disposal of the customers in such a way to define with them the hot forging processes, in order to achieve the best result in the production also of high tech parts.
