Impact extruding may be broadly described as the making of a part by placing a disc or a slug of metal into a die cavity and applying pressure with a punch. The pressure forces the metal to “squirt” up the side of the punch, the wall thickness of the part being determined by the clearance between the punch and the die. The basic difference between impact extruding magnesium and other metals is that magnesium parts must be made at an elevated temperature. These temperatures vary from 150°C to 380°C, depending on the speed of the operation and the alloy being used. Impact extrusion has historically been used for the production of many structural components, that otherwise could not be made. Historically 100’s of impact extruded application have successfully employed magnesium.
