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.

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;
- Deliver at customer site in Brescia a new ME150/4G62 hydraulic press, exactly the same one the customer saw and tried.
Why the company under consideration chose Mecolpress?
We thank the customer for the trust and for having tested us, and we are particularly proud that even they, as other customers, after having bought and used the hydraulic presses of our competitors, have chosen to purchase Mecolpress for the future.
The decisive points for this new positive result are in short:
- Mecolpress can offer to the customer not only any kind of new presses, but also exceptional expertise in the maintenance of old presses, of other manufacturers (in this case Rovetta).
- Mecolpress hydraulic presses, both for mechanical and construction project and for extremely developed software, offer to the user an incomparable ease and usage flexibility.
- Choosing Mecolpress, the possibility to conclude an investment in very short time, and to see it becoming rapidly productive; who wants to invest has no time to wait and must be helped to be competitive as soon as possible!
Would you too like to try a forging simulation?
Don’t waste your time,
test us!
Hydraulic Press ME100, the SuperFast!
Forge up to 60 pieces per minute without flash!
Our range of hot forging hydraulic presses ME has been enriched with the latest model ME100. It is a compact machine, dedicated to the forging of low-weight complex pieces, with extremely high productivity.
Mecolpress patented hydraulic presses, suitable for hot forging of standard and special brass or aluminium pieces.
This clamping force is higher than those of traditional mechanical presses. Independent & controlled movements of the ram and punches allow for flash-less hot forging also of complex pieces.
In addition to the ME150, ME250, ME350, we now also offer the ME100:
- 100 Tons of die closing force;
- 30 Tons for each of the punches (there can be up to 5)
- Forge in single or double figure, horizontally or vertically, and it is Super-Fast!
We tested it up to 30 strokes per minute and of course … it was promoted with full score!
As for all our ME hydraulic presses, the range of pieces that can be forged is very wide.
Here is a photo of typical brass parts that can be forged with this press:
Some info as an example:
– it can print ball valve bodies up to 3/4 inch, without flash (in single figure), or 1/2 inch in double figure.
– Accepts dies size 180x180mm.
– Punches stroke: 75mm.
Mecolpress has in fact the skills and the appropriate structure to make you ad hoc consultancy. Through the drawing of the piece you want to forge, we can perform a die simulation through the dedicated software in our internal technical office.
It will also be possible, if necessary, to carry out a real forging test of your piece thanks to the machines that we always have available at our company to carry out forging tests. We are thus able to offer you the machine, or the most suitable forging line for your needs.
And if the right press for you was not the ME100, we are always able to make the specific proposal for the needs of each customer, because Mecolpress has the widest range of hot forging presses of all!
HEAVY SERIES MECHANICAL PRESSES
Mecolpress, at the EMO exhibition in Hannover which took place last September, officially presented the new series of eccentric continuous cycle mechanical presses, the HEAVY series.
Based on the experience accumulated over 50 years of designing and manufacturing presses for hot forging metal, we have succeeded in creating a totally renewed mechanical press.
We are sure that our new project will mark the beginning of a new era for hot forging!
What are the main strengths of the new HEAVY mechanical presses?
-
- A structure that is certainly innovative and modern, more robust and designed to simplify control and maintenance;
- Fully revised die automation and lubrication;
- Our innovative hydraulic cushion, the Soft-Impact, which allows to achieve important results including for example the possibility of vibrations reducing;
- The updated version of our intelligent Calipso software, for the analysis of the production process and for predictive maintenance.
Let's analyse the features in detail:
STRUCTURE
The structure of the machine is made in such a way as to separate the dangerous area (moving parts and die area) from the areas accessible to the operator for adjustments and ordinary maintenance, through front protections and soundproofing material casings, as required by CE standards.
Directly on the vertical part of the forging area, the fume extraction is obtained through metal ducts with connection to the customer’s centralized system.
The control unit for centralized lubrication of the press, the regulators of the pneumatic system and of the die lubrication system and the electrical equipment are inserted in large protected cabinets and easily accessible to the operator, not reached by the fumes and the oil of die lubrication .
The assembly of the main parts to the machine is designed to simplify inspection and maintenance.
COMMAND GROUP
It includes a compact transmission coaxial to the eccentric shaft including:
– Combined flywheel and reduction unit;
– Combined Hydraulic Brake-Clutch Group, equipped with progressive piston to mitigate shocks and transmission vibrations due to engagement and braking;
– Control valve of the Brake-Clutch group with progressive engagement and braking control;
– Double gear coupling between eccentric shaft and transmission to avoid the transmission of shocks from the crank mechanism to the control unit;
– Main motor with encoder and closed loop control, allows the slow movement of the press for tooling, “Inching mode”.
The flywheel motor system has been completely revised to obtain better resolution and precision in speed control, greater reactivity in the recovery of energy after forging.
A safe speed limit control is foreseen with open front protection, during the set-up phases and a check of a possible excessive slowing down of the machine (for example due to a too large billet).
The motor cooling is constantly ensured regardless of the motor speed, this allows to always guarantee maximum performance.
We have provided an interesting option: the energy that the motor returns to the inverter during the slowdown phases, is put back into the network and not dissipated in heat; in practice it translates into a lower consumption of electricity!
SLIDE
Also the slide has been revised, we have foreseen a motorized adjustment of the vertical light and an extraction bar with hydraulic control.
The sliding skids are oriented radially to the machine axis to reduce the variation of the tolerances with changing temperatures.
The hydraulic system for protection against overload is also inserted in the slide, which is essential for forging on the bottom.
GE EQUIPMENT
– Possibility of mounting the lower punch also with “SOFT IMPACT” cushion,
– Water cooled upper die holder,
– Up to 8 points of lubrication from the lower die holder,
– Up to 4 points of lubrication from the upper die holder,
– Easy equipment change. It is extracted by unlocking the top with pistons that allow extraction on a ball guide.
– Possibility of mounting the motorized adjustment of the punch stroke.
For the HEAVY400 the GE26 is foreseen, which has the following specific features:
– Dies 290 x 290 mm
– 110 mm punch stroke
Thanks to our Extruder Group you can save up to 40% of the material compared to the full forging modes! Check out the details here
“SOFT IMPACT” CUSHION
1000 kN hydraulic cushion with complete electronic management, it allows to check the punch height, in addition to limiting the mechanical shock due to the impact between the dies.
The Soft Impact cushion is an important innovation that we have been making for a couple of years, and that is proving to be truly appreciated. Read here to learn more about how it works.
BRCE LOADING DEVICE
The 2-axis rotary loading arm driven by brushless motors has the load angle of the clamp at 45 °, aligned with the dies centre;
The 400 mm vertical stroke allows you to manage any type of equipment without manually changing the position of the arm.
PBSE DISCHARGE DEVICE
The discharge chute has been designed to avoid dents to the forged part; driven by a motor brushless, the unloading arm allows automatic adjustment of the position.
DIE LUBRICATION
We have provided up to 20 lubrication points and 2 dies blowing points, an open and flexible configuration for each type of die and tool.
Also interesting is the possibility of adjusting the amount of oil from the panel, without need of manual adjustments on the machine and on the control unit.
From every point it is possible to blow air to clean / cool the die before every lubrication.
The press is able to warn in advance when it is necessary to fill the hydraulic unit, in order to avoid a machine stop due to lack of fluid.
A digital sensor allows the control of the fluid temperature, the operator can start the production only when the oil is at the correct temperature, an essential requirement for a correct and constant lubrication.
An inverter for pump speed adjustment prevents overpressure peaks and oil dripping when the pump starts with oil still cold; automatically adjusts the oil flow rate according to the quantity needed for use; prevents overheating of the oil in the control unit.
Our lubrication system, unlike the systems marketed up to now, eliminates the problem of the quantity of oil usable for each individual nozzle.
Competitive lubrication systems load a limited amount of oil into a tube and then blow it off with compressed air.
This ensures that 70% of the sprayed lubricant is used only in the first moment of lubrication, while in the remaining cycle the quantity of lubricant decreases until it is completely zeroed.
On the other hand, our lubrication system allows continuous and constant mixing directly at the exit point of the pipe, through our system we can cool and lubricate the dies from the same pipe without affecting the programmed oil quantity.
ELECTRICAL CONFIGURATION
The 24vcc circuits are protected by auxiliary electronic devices, able to provide a quick diagnosis of any short circuits or overloads (also through Teleservice).
This is a very interesting aspect because it allows a greater reliability of the system and a service life up to 10 times greater than normal technology!
The cables are in PUR, protected by steel sheaths and silicone protections against flames, specific for use even in environments deemed aggressive.
OPERATOR INTERFACE
The Operator Panel is a 15 ″ Siemens Touch Panel to better manage machine data, you can save up to 1000 recipes! And have an alarm history with up to 10,000 events.
Obviously, through the proper configuration of our software, you can receive valuable reports to carry out preventive maintenance.
Another practical example is the notepad function, thanks to which the operator can then write important information and his personal notes, added to each production recipe.
It is possible to obtain a production report, a secure management by 4-level password with autologon function, and much more.
Finally, the movable panel allows close controls on the machine, possibility of movement and programming with front or rear open protection, close to the die (eg die lubrication).
Screw presses
Come to discover the application sectors and the functioning of Mecolpress screw presses. Used for hot forging, these presses can be employed with every type of material and are distinguished by the realization of full parts.
Screw presses functioning
Mecolpress offers a wide range of presses both hydraulic and mechanical. Also screw presses fall into this last category, ideal for hot forging of parts of great dimensions or that require more passages for shaping. These mechanical screw presses can be provided with a disc friction control or a direct control with electric servomotor.
The screw press choice is determined according to the type of part you want to forge. Hallmark of the screw press is its ratio force-machine dimension, that results greater than the specific one of an eccentric mechanical press.
These mechanical presses can be used with every type of material and the frequency of strokes is quite reduced. For this reason, there is a tendency to use this machine for the production of little batches, that is often true for parts of great dimensions.
Mecolpress offers to its customers three lines of screw presses: Dellavia series and Osterwalder series that are friction screw presses, and TDS series with electric motor. All the screw presses models can be integrated with complete and automatic forging lines, that from bar raw material realize finished forged parts.
The tonnage can go from 170 tons up to more than 2.700 tons, to be chosen according to the geometrical shape you want to obtain and of course to the material to be forged.
The applications
The screw presses are used for the realization of parts destined to different application fields including for example, watch cases, parts for sport equipment, for automotive or for biomedical titanium prothesis.
So, it is possible to produce very small parts, such as for example, clothing zipper pullers till to aluminum sport bows of 1 m of length. The parts, produced by this type of machine, are not cored but full.
The screw presses are very used also in the fashion field to realize belt and bag buckles, with brand-specific shape.
In order to understand which model is more suitable to your production needs, all you have to do is to address to Mecolpress sales department. Thanks to the experience gained with years of activity in the hot forging field, we can suggest the most performing machine according to the type of part you want to forge, and it is possible to carry out a test directly at our premises.
Forge gate valves with a ME Hydraulic press!
In this video you can see the hot forging of gate valves with a ME hydraulic press.
Go beyond the normal criticality of the forging of these valves, get a piece without flash and reduce production costs.
What are gate valves and how they are traditionally forged?
The brass or other materials gate valves have the function of fluid flow adjusting and stopping onto a tube. They fulfil this control through a hand wheel (or a motorized actuator).
To give you an idea, you can compare the function of the mentioned valve to the closing of a gate slide in the middle of a tunnel flooded by the water.
Usually the gate valves are hot forged through traditional eccentric mechanical presses, but their realization is not easy, above all if you want to forge the part without possible defects, using little material (therefore with the most possible depth of all the holes) or without flash as well.
The traditional forging of gate valves by means of eccentric mechanical presses requires a greater energy compared to the one necessary for forging of ball valves having the same dimensions, and it requires a much higher punches stroke, in particular for one of them.
For example, for the realization of gate valves of 2 inches or more, eccentric mechanical presses of minimum 450 tons capacity and a forging tool (defined as bell tool) that allows the realization of holes of great diameter are normally used.
This technology has been valid and successfully used for many years, and Mecolpress as well proposes it to its customers through its SEO and SEO CVE CS presses series.
Gate valves forged by means of hydraulic presses
There is also a much more efficient way for gate valves hot forging: ME hydraulic press.
ME hydraulic presses, in fact, thanks to the different working dynamics of the punches, are proving to be really decisive for all the forgings of more “problematic” and complex parts, consenting for example to avoid the use of EV bell tool.
As we show in this video by means of ME presses you can forge high quality gate valves, without flash, detail of great importance. The presence of flash in the forged parts implicates a considerable waste of material, and moreover, to remove it, it is necessary to use a trimming press, which means therefore that you will have to equip yourself with an additional machine.
Another interesting aspect to be underlined is the fact that hydraulic presses have a cycle frequency significantly higher than normal mechanical presses.
Our ME hydraulic presses have also as standard equipment the Calipso software, our innovative program for collecting and checking forging data. Through this intelligent system you can perform analyses of the production process, but not only! In fact, it is possible to obtain an optimal and separate management of any pieces to be discarded or otherwise to be evaluated.
The checking of the pieces carried out by Calipso guarantees the certified quality of each piece produced.
Another important advantage that is standard on our ME hydraulic presses is the innovative die lubrication system, that can also be optionally applied to eccentric continuous cycle presses. In hot forging it is important not to underestimate the way in which the dies are lubricated; finding the “perfect” lubrication in your forging process ensures an increase in the life of the dies and materials unattainable with traditional systems!
The ME hydraulic press has an innovative forging system compared to traditional mechanical presses. Innovative because, for example, it does not generate mechanical shocks, it considerably reduces the noise generated during production, the tooling is much faster and more convenient.

Why to choose Mecolpress presses?
Mecolpress makes available to its customers quality presses and all its technologic know how. For those who need high performing machineries for hot forging we are a reliable and with a solid experience partner in this field, gained in many years of activity.
Whether it is an entire forging line or a single machinery, Mecolpress can suggest the most performing solution for production and offer a technical support able to face every need.
A first meeting to understand the necessities
When a new potential customer contacts us expressing its need to buy a press, our sales department organizes immediately a first meeting either at customer’s or at our premises in order to show the different machines and their functioning.
During this phase, to us it is of fundamental importance to understand the types of the parts to be forged and which could be the eventual criticalities connected to the single parts in order to be able to propose the most suitable press. In many cases our offers are based directly on the drawings of the parts to be forged that are analyzed by our technical office in great details.
In order to understand which is the best press, our technical office takes advantage of a software that can simulate on the computer the action of the machine. In this way we provide a valid tool for the identification of the machinery that meets the productive needs.
Some customers in addition to the single press require the entire hot forging line and, in this case as well, we can provide all the necessary machineries, and to optimize the production.
Forging tests at Mecolpress
Once the most fitting press for the customer has been identified, even if this is hydraulic or mechanical, we carry out forging tests at our premises. So, the customer can be sure in advance of the final result before starting the production at his premises.
In order to carry out the test, the dies for the realization of the wished parts are mounted on the machine. In case the customer does not have the die, there is the possibility to commission it directly to Mecolpress. Indeed, our company offers a complete service to support the customer during all the productive steps and can also offer this component.
During the many years of activity we have gained high technical skills and we have confronted with different situations. The gained experience has turned us into a partner that can understand the forgers needs, able to propose mechanical or hydraulic press for a specific production type.
