ADVANTAGE

Compared to the traditional drawing technology foreseeing the auxilium of a punch and of a matrix, the hydroforming process needs only using one part of the traditional die.
The economic advantage arising from this technology permits to low the investments cost for the equipment of about 60÷70% if compared to the traditional drawing system.
The die consists of the matrix (female) of the geometry of the piece to be drawed. Once such shape has been obtained by using a CNC machine it is possible to mount it directly into the hydroforming plant and to draw immediately the pieces required.
Therefore every die adjustment activity is eliminated as well as the following optimization tests.
The series SLC can be equipped with a particular die hooking system which allows for its being equipped in a few minutes. This system solves the problem of the frequent production shifts and permits to the user to be very flexible and competitor in shifting from one manufacturing lot to the other, taking into account that a lot consists sometimes only of five/ten units.
Die hooking is carried out by electro-permanent magnets having a lifting capacity of up to 100 ton.
It is enough to position the die on the front machine feeding shuttle and the automatic system can then set the die in the proper site without it being necessary any further adjustment and therefore the proper alignment with the machine get assured.
