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).

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!

With or without flash?
When you have to face a forging project for a new piece, the first step to take is to make a simulation by means of forging software and to decide whether to set the simulation with or without flash.
With or without flash?
Start with the forging simulation
In general terms we can affirm that thin-thickness pieces and material movements in different directions or with sudden dimension changes can give defects in flash free forging.
If the geometry is uniform and the section variations are contained, you can think of dealing with a flash free project.
It is true in all cases that starting a flash free project can allow evaluations that push to optimize the geometries of the piece (if it is possible to operate on the outer geometry) or it can drive the next analysis with flash.
A first flash free step involves certainly reduced calculation times and allows an evaluation of the punches forces and dies closure that can approximatively be considered valid in general.
Suitable for forging with flash
Here above a geometry that very hardly is fit for a flash free forging
Suitable for flash-free forging
In this case, the success of a flash free project is very likely.
Is the press you have chosen suitable for forging your piece?
Secondly, it is necessary to roughly estimate if the analyzed piece is workable for the considered machine model.
At this stage you need to have a database showing the average pressures on half dies and on punches.
For this purpose, as the simulation history evolves, it is very useful to keep an Excel file in which the results in terms of forces are summarized in average pressures on half dies and punches.
This procedure allows you to understand at a glance if the result of a simulation can be considered valid or may be affected by calculation errors. Obviously, more cases are available more is likely to have reliable results, because the geometry of the piece strongly affects the force on each element of the die and therefore in the evaluation it is necessary to consider pieces with similar morphological characteristics.
Once the geometry of the piece is drawn, including the desired corings, it is necessary to obtain by subtraction the geometry of die and punches.
Firstly, however, the shape has to be scaled to take into consideration the fact that the formation occurs at a high temperature, while the drawing dimensions are valid for pieces at ambient temperature.
The typical brass value for forging is 1.012, while in the case of aluminum the factor 1.010 is generally used. With an Excel sheet, you can therefore estimate the diameter and length of the billet of first attempt.
For flash-free forging choose the hydraulic presses
Mecolpress hydraulic presses of ME series are the best solution for the forging of a part of brass, aluminum, or of other materials, without flash.
The closing force of the dies, higher than the one of the traditional mechanical presses, and the independent and controlled movement of the ram and of the extruders allow the hot forging of even complex parts without flash.
ME hydraulic presses have proved to be unbeatable in the forging of parts having some complexities.
For example, if you have to forge gate valves, our ME presses allow to forge these valves totally without flash, with very high precision, without the risk of defects caused by brass flow in the die.
In addition, even the production is higher compared to the one allowed by the traditional method with eccentric mechanical presses and with bell tool.
A ME350-4G240 hydraulic press, for example, can forge two-inch gate vales without flash, without the help of special tools, and with a productivity of about 800 parts/hour.
Another significant and practical example is that with a ME hydraulic press you can hot forge 4 brass parts at a time without flash!
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!
The dies lubrication determines your forging success!
Knowing to take advantage of the correct dies lubrication is crucial in a hot forging system of brass, steel, aluminum, titanium or copper parts.
We have already highlighted many times in our previous articles how the lubrication can make the difference and solve many of the common problems that the forgers observe during the production of their forged parts. Our research of the perfect lubrication has evolved, becoming more and more precise and customizable, exactly like we are constantly required by the market.
A correct lubrication doesn’t mean that it must be of large quantity, but that it must be correctly dosed and the most appropriate lubricants must be chosen according to the metal types and required part to be forged.
The dies lubrication system of hydraulic presses of ME series and of eccentric press at continuous cycle of HEAVY series
With the hydraulic presses of ME series and the mechanical eccentric at continuous cycle presses of HEAVY series we have revolutionized the dies lubrication system:
- We drag the outgoing oil+graphite mixture on the lubrication point.
- We let the lubrication liquid and the compressed air flow in two concentric tubes of the control valves of the single points up to the usage point.
- For each of the points the pilot is independent and therefore for each of them we give the possibility to the user to choose from the operator panel how, when and how often to intervene.
But we were not satisfied yet!
Which are the requests the forgers most frequently address to us?
We have verified that some of the questions you ask our service department are regarding the lubrication system:
“My die has broken, what can I do to guarantee it a long-lasting life?”
“The dies lubrication system I am using is not satisfying.”
“Is it possible to reduce the waste of lubricants, in view of an even more ecological choice?”
“How can I obtain a successful forging system?”
Our Research and Development team has therefore perfected and developed a new lubrication system.
What’s new in the lubrication system of the HEAVY series
Heavy series is our new proposal of a mechanical eccentric at continuous cycle press. It is a very revolutionary machine, the result of 50 years of experience in the hot forging presses production, and of the continuous search for innovation and technology perfection.
As a result, we have completely reviewed even the automation and the dies lubrication.
First of all, the dies lubrication system allows for each single point the independent and programmable management.
It is possible to start the lubrication cycle in different ways: during the ascent or descent of the ram, during the loading or unloading cycle, with appropriate delay and duration times.
Each point can be used for the nebulization of the lubricant or for the cooling and cleaning of the dies.
The system can be implemented with 2 or more high capacity air blowing points.
It is possible to program the schedules: the pumping circuit, the automatic mixer and the heating resistance placed in the tank allow to prepare the liquid and the entire circuit for the starting time at optimal conditions.
The nebulization of the lubricant, thanks to the particular pipe system, is obtained only in proximity of the usage area: in this way the dosage, repeatability and the sensibility to the dosage variation are guaranteed.
40 lubrication/cooling points are foreseen, of which 16 are placed in the lower dies-holder and 16 in the upper dies-holder. The disposition of the lubrication/cooling points throughout the dies allows to reach efficaciously the critical points to be lubricated/cooled, in addition to drastically reduce the times of production change.
Reactive, smart system for creating your recipes
The responsiveness to the settings variations is immediate, unlike the traditional system that requires several minutes of production before it stabilizes.
In addition to this, we can have a strong blowing without the help of compressors (that are contributing to increase the consumptions and the general maintenances of the plant).
A smart software system helps moreover the operator to adapt automatically the dosage of the lubricant in the startup phase of the production, till to reach the correct forging conditions.
Our system can be adapted even to the use of lubricant/water-base release agent, e.g. used in the aluminum sector, that are different from the classic graphitized oil.
All the parameters, activation of the used points, start modalities, timers and counters, once they have been optimized, are saved in the recipe devoted to the type of the part to be produced, in order that for the following batches of the same article there is a fast production start without useless waste of time.
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.
Another company based in Brescia chooses Mecolpress hydraulic presses.
With regularity and continuity, Mecolpress gains new Italian customers, the hydraulic press is confirming to be the winning choice.
Case Study: How we acquired the latest customer from Brescia
We report the case of a new customer based in Brescia that we have just acquired, an interesting case study to understand which are the necessities of the companies working in the hot forging sector and how Mecolpress provides answers.
It is the case of a company established in the international market for the very high quality of its production, consisting mainly of mini valves, valves and fittings for the sanitary and heating sector. This company has its own brass hot forging department, developed to cover the 100% of the forged parts needs; the recourse to very few and highly selected external suppliers happens just in case of particular peak of volumes.
The presses equipment of this company consists of 5 machines, always full of work: 3 more traditional and “dated” (eccentric mechanical presses of the historic producer Rovetta, that now no longer exists) and two more recent little hydraulic presses of a particular type, proposed by an European producer.
Knowing better the company, now customer of us, we could appreciate right from the beginning some undisputed features:
- Advanced transfer machines;
- A working method focused on the precise and deep knowledge of all the productive processes;
- A forward-looking vision on the continuous training of all the personnel that is involved with the management regarding the strategic decisions and that creates a uniform a close-knit group;
- A quality department having knowledge, methodologies and instruments not only for the examination of the parts but also for the evaluation of the method used for their production.
During various meeting both at customer’s and Mecolpress site, we had the opportunity to present them our complete range of presses and in particular the functionalities of our hydraulic presses of ME series.
Mecolpress method
The customer wanted to test us, taking advantage of the Mecolpress strategy of having a selection of presses almost ready for delivery, for carrying out forging simulations with two parts of their production range on the specific press of their interest.
The result was that, thanks to the constructive collaboration of both teams (the customer and the Mecolpress ones), in just 9 weeks from the decision of beginning with the simulations, we could:
- Carry out the forging simulations of the two parts to be tested;
- Manufacture the related forging dies;
- Carry out forging tests with two dies (in manual and in automatic cycle, since Mecolpress has 2 high-performing push-type gas furnaces;
- Dismantle and demolish one of the old presses of the Customer;
