Before a material is shaped with a cold forging press, the material undergoes surface treatment processes to prepare the material to be forged. This process provides a number of important benefits.

  1. Preserve the life of the forging die – metal material with smooth surface reduces friction between the material and forging die, and thus protects the forging die from wear and tear during the forging process.

  2. Improve dimensional accuracy – cold forged product produced using material with smooth surface has superior dimensional accuracy. As a result, forged products have smooth surface.
