What is Impact Extrusion?
Impact extrusion is one of the cold forming processes used for the larger sized products. The process starts with a volume controlled “slug” contrary to the cold heading process that starts with a wire. Stalcop impact extrusion capabilities currently include diameters up to 4 inches and lengths up to 16 inches handling volumes from 1,000 to multi-million pieces per year. These capabilities are not restrictive as our investment focus on new opportunities to meet our customers needs. The most common impact extrusion techniques are — “forward extrusions” and “backward extrusions.” The creativity the design engineer can enable both of the techniques to be used simultaneously to minimize production cost as many designs include both extrusions.
