Abstract (en)
[origin: EP1053801A2] The device has two relatively moveable lockable molds (22,42). The first mold is held on a hydraulic piston (16) moving in a cylinder (6), carrying a first press die (20). The second mold is stationary and positioned on a second hydraulic cylinder (26), the second press die (40) is located on a second hydraulic piston (36). During impact extrusion of a component, the second pisto charged by a pressure medium displaced by the first piston. The first hydraulic cylinder is is positioned on press ram.
