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.
STEEL HOT FORGING: THE WORD TO OUR EXPERT
We interviewed Luca Di Donato, Mecolpress specialist for steel hot forging.
Steel is a far different material from brass, for this reason Mecolpress has decided to increase its team with a devoted figure, to whom we have addressed some questions.
Let's talk about steel hot forging
What is your role in Mecolpress?
The role I currently play in the company context is project engineer manager specialized in steel hot forging and non-ferrous alloys (except brass).
Specifically, I mainly deal with the identification and definition of the hot plastic deformation process that is technically and economically most suitable for the production of semi-finished steel components but also aluminium and special nickel and Titanium alloys.
What kind of experience do you have in steel hot forging sector?
The gained background in the specific sector derives from many years of work experience acquired in the company field, initially as a designer and then as technical and operational director of companies located in Italy and abroad.
Which application sectors do usually use steel hot forging presses?
Presses for steel hot forging are widely used in many application sectors such as automotive, aeronautics, agriculture, construction, chemical, petrochemical and industrial sector in general.
Which type of machine is most suitable for steel forging? (mechanical presses, hydraulic presses, screw presses?)
From a metallurgical point of view, steel can be forged using every type of press, since the types of steel in general are little affected by the presses deformation speed as some aluminium alloys and the super alloys of Titanium and Nickel are affected.
Therefore, there are other parameters that influence the choice, in fact the geometry, the geometric and dimensional tolerances can certainly guide the choice on a mechanical press rather than on a screw press, but also on a hydraulic press.
Compared to brass, which are the distinctive traits of steel?
From the process point of view and therefore from the point of view of the relative presses, the first aspect that is typical for steel is certainly the forging temperature which is around 1200 ° C.
The other equally important feature is the steel deformability which is far more difficult than the one of the brass. The resistance to hot plastic deformation of steel forces the adoption of simpler geometries, the adoption of presses with increased capacity in terms of forces, moreover, pre-forming processes are often used.
According to your experience, which are the recurring critical issues that you could observe in the forging of this material?
As previously highlighted, steel is forged at high temperature, therefore possible overheating can be created in areas that are particularly subject to deformation, the involved forces are important and as a result the energy and disposition can approach the limit and cause no geometric conformity on the piece.
In the end, steel cannot be easily deformed and therefore it requires a specific study to understand which preforming processes are better to adopt in order to avoid cracks / folds of material.
Always according to your experience, when we want to choose the most suitable machine, what should we absolutely consider?
Obviously the geometry of the forged product to be obtained, together with the imposed geometric and dimensional tolerances, strongly influences the choice of the best process, first of all the type of press but also all the machines necessary to compose the line, from the cutting, heating, and preforming process up to the possible calibration of hot / cold forging.
Mecolpress, through the specific skills acquired in fifty years of working history and thanks to its professionalism, is able to support the customer from the very first stages of defining the most suitable geometry for the choice of the forging up to the realization of the line, also fully automated, turnkey.
What do you think that can really make the difference in a “guessed” press?
The heart of the production line in its entirety is the PRESS which has been designed to respect specific characteristics, as a result “guessing” the type of press is absolutely important, but it is equally essential to consider who designed and built it, in this regard the presses produced by Mecolpress are considered to be among the best on the market, both in terms of technological content and in terms of rigidity and reliability.
