Types of heat treatment business

Nitride mold processing technology

HPN treatment (Hanguk Plasma Nitriding)

Heat Treatment Business Features

- With the existing nitriding treatment, modifying the mold is difficult due to the chemical compound layer of the mold.

- HPN mold processing is a nitriding technology that generates only the diffusion layer, making it easier to modify the mold (weldability)

- Uniform nitriding on large-scale 3 dimensional mold is possible

- Mold life is increased by more than double through surface modification.

  • 100% improvement of surface hardness
