Elastoforming

Vertical press with hydraulically actuated lateral pressure cylinders (internal development).

Rubber pad forming (Rubber Pad Forming)

Rubber pad forming is an industrial manufacturing process for the production of shallow parts. Basically, the part acquires its final shape by forming it between two tools, one of which is rigid (often a metal punch or die) and the other is flexible (the rubber pad). The process is particularly suitable for low to medium volume production and, until recently, this forming was used almost exclusively in the aircraft industry.
Tube elastoforming

In this metal forming process a round elastomer is introduced into the tube. This elastomer is pushed by two hydraulic cylinders and will expand inside the tube die. It is used as a substitute for the more expensive hydroforming process when series are small.
