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.
The “possessed” screw press
Even when some machineries present complex problems and when it seems that no solutions are possible, Mecolpress thanks to the solid technical skills that have always characterized it, can solve the situation. A specific case is what happened to a customer of ours and to his malfunctioning screw press. Read all the article to discover the details.
Screw press criticalities
Not long ago we were contacted by an Italian company specialized in the production of spades, shovels and other gardening tools. They bought a second-hand screw press from a competitor of ours because they needed to automate the forging line for spades and shovels by means of robots. Unfortunately, immediately from the beginning, some problems of machine malfunctioning were observed.
Indeed, the screw press just after three or four working hours lost capacity of hit till to stop completely and in addiction it consumed excessively the leather belt that had to be replaced even three times per month.
It really seemed to be “possessed by demons” and even who sold the machine could not solve the problem in the first instance, even though the numerous technical interventions that were carried out.
Since they could not repair in no way the machine and thanks to the suggestions of other machines suppliers, the company decided therefore to refer to Mecolpress hoping to find a valid technical support.
Mecolpress intervention
After a first telephone contact, our technician intervened directly on the press and after a first mechanical analysis he decided to dismount the main screw looking for the possible defect inside the machine.
After a half working day our skilled technician could identify the problem: one of the bronze ring was built with a wrong tolerance and as a result it caused an increase of temperature in the screw. Therefore, the materials expanded and led to a complete stop of the machine.
Our competitors could not even suppose this problem, while our technician in just a working day could identify exactly the reason of the malfunctioning.
This case study has shown how much it is important to have available all the projects and all the technical specifications of the machines which you want to operate on. The bronze ring of the screw press was realized according to a superficial mechanical analysis and to an insufficient knowledge of the complete design of the machinery.
Mecolpress has proved to have the necessary skills and experience to evaluate when a detail can make the difference. Indeed, even some unimportant details can cover a fundamental role in the optimal functioning of a press.
Our company has revealed once again to be a reliable and expert partner you can refer to for complex and apparently insurmountable technical matter.
Friction or electrical screw press?
There are electrical or friction screw presses. Which to choose? The choice of the model is linked to the type of parts you want to forge, but also to the press performance. Discover the differences between these types of screw press by reading this article.
The mechanic friction machine is provided with a flywheel that rotates the screws clockwise or counterclockwise so that to let the slide go down or go up. In this case the transmission of the motion from the electric motor to the flywheel happens through the friction created on a leather belt. This model does not permit a direct control of the motor and of the flywheel, even if it presents considerable advantages in terms of energy saving. Indeed, a friction screw press has a medium consumption of about 40 KWh.
These presses require a smaller investment than the one of the screw presses with electrical servomotor, but they need the leather belt replacement, necessary for the slide movement when it wears.
Suitable for the hot forging of every type of material, the friction screw presses are used for the production of full parts.
This press, as opposed to the friction one differs for an electrical motor directly mounted on the flywheel, in the upper side of the machine, that rotates the screw. Thanks to this characteristic, the electrical screw press allows a better control of the productive process. Indeed, it is possible to check the descent and rise speed at any moment, to have direct feedback about the production of the machine and to calculate the necessary tonnage for the hot forging of parts you want to produce.
The electrical screw press requires more electrical energy, but its components wear less, and it is particularly indicated for the production of parts that require more strokes to be completed. In addition, it is possible to obtain much more energy with a reduced stroke, which does not always happen in the case of friction screw press. As a result, this machine has a rate of production slightly higher than a traditional machine.
The mechanical screw presses of Mecolpress TDS series are moreover provided with Calipso software, which is also developed by our company, that allows the data collection and recording in real time. In this way the end-user can do a process evaluation and intervene to optimize it.
Mecolpress proposes to its customers both friction screw presses and direct control with electrical servomotor control screw presses, developed to satisfy the different productive needs and suitable for the forging of full parts destined to sectors such as automotive, medical and sport one.
