Aluminum Impact Extrusion

Description

Impact Extrusion is a versatile forming process used to create thin wall, seamless, hollow shapes by a rapid single stroke application of force through a punch. This process has many advantages over conventional production methods such as casting and machining, saving on secondary operations, reducing waste material, reducing cycle times and offering tight tolerances over diameters and lengths.

Features

Impact V.S. Deep Drawn
Bottom Thickness:
Deep-drawn parts are typically limited to a 1:1 wall/bottom thickness.
Impact parts have no limit to wall/bottom thickness to be 1:1

Length / width ratio:
Deep draws are typically limited to a 2:1 ratio Impacts are typically limited to 8:1 in aluminum and 4:1 in steel in a single operation. Further process can triple this ratio.

Material Yield:
Material yield in strip stock for deep draw is typically 80% or less.
Material yield in impacts is typically over 90%.
