Forging

Cold forging, Warm forging, Hot forging

Forging is a manufacturing process through which a solid metal workpiece is deformed and then re-shaped using compression.
Also, forged pieces are stronger than the same piece created through casting or machining.  

For cold forging, the shapes are usually more basic and mass-produced
For hot forging, it is the best option because of its malleable state before hardening. This method is ideal for creating 3D and complex shapes.


Both forging methods can be effective ways to strengthen and form your metal workpieces into the final product you need.
