1. Process description
The term extrusion is commonly used with the same meaning as cold forging; some even refer to cold forging by extrusion. We use all these terms with the same meaning.
The significant development of cold forging can be explained by the many direct and indirect economic advantages it brings to the design, manufacture and use of the products it produces.
The design of a cold-formed part enables :
In addition to the ability to produce draft-free shapes, it can also be used to produce complex geometries that are often impossible to achieve under industrial conditions using other processes (e.g. polygonal, cylindrical or conical internal shapes, blind, spherical, truncated, etc.);
for an equivalent grade, to lighten the part,...
