Swaging Process (Rotating Cold Forging Process)

The swaging process (rotating cold forging process) is a process in which a divided die rotates and is hammered to squeeze the outer diameter of a round bar or pipe material.

The Benefits of Cold Forging

  • Cost reduction can be achieved by eliminating material waste and loss.
  • The strength of parts can be improved by work hardening.
  • Environmentally friendly

Three Features

A Beautiful Surface Finish

Material costs are reduced because material powder is not produced during the cold forging process. It creates an extremely beautiful processed surface when compared to conventional cutting processes. Metal tubes and solid materials etc. are formed by hammer processing. A wide range of dimensions are possible including steel pipe columns. Surface roughness can be improved by high-speed striking technology through rotary forging.
Beautiful Surface Finish

An Increase in Strength

The strength of parts are increased by work hardening. It is also used in automotive part manufacturing.
