SLC PLANTS

Since hydroforming requires uniform pressure across the whole piece, the corresponding necessary clamping force results to be elevated.

It was clear then that in order to exploit at the best every benefit from the hydroforming process it was necessary to study a new plant typology which would assure: a higher compactness, an elevated force-weight ratio and which would be very convenient from an economical point of view. The strict specifications imposed to our technical dept. did require also a machine practically without any elastic movement, which would have entailed a notable waste of energy, and whose light must be the most possible reduced in order to increase its rigidity.

Following to this careful and deep study the SLC series machines were born, they are characterised by a max height of about 4 meters and do require foundations not deeper than 1 meter.
It was possible thanks to the particular cylindrical shape characterising their building philosophy.

To get the maximum speed of drawing process a pressure intensifier has been conceived for the series SLC which allows to get to elevated pressures, several thousand bar and to feed the process by elevated quantities of fluid.
By this system the process time periods result to be absolutely comparable to the traditional drawing tecnique and in certain instances even quicker.

Self-learning, indispensable in hydroforming, which can be get by the most sophisticated hardware and software systems installed in command panels and command pulpits designed and realized by us permits to vary at the same time and in a controlled manner the pressure of the fluid as well as the clamping force of the machine.

Sheet, as a matter of fact, must slip in a controlled manner, as in traditional process, into the die in order to feed the material deformations during the drawing cycle.
This control is carried out in traditional technology by the blankholder.In Hydroforming the blankholder's function is managed, without the blankholder, by the software foreseen in the SLC series.
The program modules the clamping force of the machine, thus assuring that the sheet will be sliding at the proper speed during the drawing cycle.
Thanks to this device it is possible to simplify drastically the construction of the dies.
As a matter of fact the Hydroforming die consists only of a single element.

The software mentioned above is installed in the PC of the machine in complete Windows © operative system.
In addition to that, every data of the machine is managed by a relational Database, Microsoft SQL ©, which interfaces easily with the management part of the company.

SLC series foresees the possibility to activitate the failure a/o alarm tele service, directly from the site of Muraro.
