The cold forging manufacturing process is performed at normal room temperature. The work piece is squeezed between two dies until it has assumed the desired shape. To deliver a finished, ready to fit component, the technique includes rolling, drawing, pressing, spinning, extruding and heading.
Advantages:
- cost saving as very little or no finishing work is required.
- High precision, Economical.
- High production rates and long die life.
Drawbacks:
- Only simple shapes in large volumes can be shaped and hence not suitable for customized components.
- Low ductility.
- risk of Residual stress.
