hot stamping mould

In view of the complex production conditions of hot stamping die, hot stamping die steel has the characteristics of high wear resistance, high toughness and high thermal conductivity. In view of the wear resistance and coarsening of the hot stamping die during use, we adopt the ion nitriding treatment technology on the surface of the hot stamping die and the original nitrogen layer adjustment process, which is higher in toughness than the traditional ion nitriding. After ion nitriding, the thickness of white bright layer can reach 8-10 μ m. Nitriding layer thickness: 200-300 μ m. The surface hardness of the die reaches 10000hv, which can significantly improve the roughening problem of the die.
