Metal forming
Deep-drawing and forming presses for sheet-metal parts, cookware and complex shapes, where pressure control decides whether a part forms or tears.
In deep drawing, the sheet is pulled into the die to form a cup, a pot or a complex shell. Too little force and the part does not form; too much, or force applied unevenly, and the wall thins, wrinkles or tears. The press frame must also stay rigid so the two halves of the die meet in the same place on every stroke.
Pernoscal's deep-drawing press (PSG-HPDD), from 40 to more than 1000 t, gives precise control of hydraulic pressure through the stroke, which suits deep parts and complex geometry. The four-column frame guides the moving platen and keeps it parallel to the bed, protecting both the part and the tooling.
For general forming, such as cookware, pressed parts and assembly work, we size four-column presses to the job. Send us the part drawing, the material and its thickness, and our engineers will estimate the force and propose a press.
Questions
How do I estimate the press force (tonnage) I need?
Required force depends on the process, the material and the size of the part. For moulding, it is mainly the pressure the material needs multiplied by the projected area of the part. For deep drawing, it depends on the strength of the material, the sheet thickness and the perimeter being drawn.
Add a margin above the calculated value so the press is not working at its limit on every cycle. Our engineers can check your calculation from a part drawing and the material data.
