Cold forming is based on the selected material, according to the shape of the part from the material structure can determine the characteristics of the quality of forming parts. The structural properties of the material will favor the choice of the forming method, the various forming methods or the composite forming, but the following three are the basic forming methods:
Forward squeeze
A forward extrusion is a method of extruding in a reduced diameter at a reduced percentage rate by extrusion or truncation to reduce the diameter.
Reverse extrusion
Reverse extrusion is to form the hole extrusion method, the reverse flow of infiltration of materials around the die.
Upsetting
Upsetting is to form a fastener head of a method, the material from the mold surface from top to bottom upsetting, according to the different parts shape, can be used open or cut-off of the upsetting mode.
