The impact of speed
The impact extrusion process is one of the fastest ways to get to near-net shape for many parts and components. Our process begins with a lubricated metal slug—also called a blank or a puck—that is placed in a die cavity.
The metal puck is struck with a punch powered by a mechanical or hydraulic press. This forces the metal to flow into a shape or position almost instantly.
The resulting shape of the extruded part depends on what type of impact extrusion is being performed: reverse impacting, forward impacting, or combination impacting. Below are graphics that highlight the key differences and attributes of the three main types.
