Elastoforming

Our large press with a force of 6000 tonnes is also suitable for elastoforming sheet metal.
Elastoforming is a technology for working sheet metal widely used in aeronautics applications where for safety reasons technical regulations do not allow the forming of sheet metal by a die in which the punch and matrix are also metal.

Elastoforming is used to obtain pressed parts by means of pressure applied to an elastic (rubber or polymer) matrix in a die carrying the sheet of metal.

• Placing the sheet of metal in position between the die and elastic matrix
• Thrusting the sheet of metal against the elastic matrix
• The sheet of metal is further pushed against the rubber which impresses the required shape

For the product:

• Absence of the strain typical of conventional pressing, due to concentrated stretching points (on corners, bending radii)
• High precision in terms of constant thickness

For the process:

• Excellent repeatability of the parts produced
• Simple economical tools
• Reasonable production costs

Elastoforming also allows a different approach to conventional product development processes:

• why cut, bend, weld (and brush in the case of stainless steel)?
• when a press can do it all, with minimum outlay for a die!
