The Extrusion

The Extrusion Process
Extrusion is a method of forming in which metals or plastics are forced through a die or series of dies, resulting in a specific shape of constant cross section.
With the proper tooling, extrusions may be tapered or
stepped. Extrusions can be either very
thick in cross section or very thin and be either solid or hollow. The
extruded stock, which can be 100 feet in
length or longer, is then cut to a convenient stock size and used as
specific products, assembly components, or as raw sto
ck material for further processing. Extrusion size is
expressed as a circle size which relates to the sma
llest circle diameter which can enclose an extrusion’s
cross section.

Metal Extrusion

Metal extrusion processes may be performed hot, warm, or cold. Each method has its own unique operating
