Surface treatment technology is an important means to improve the life of die casting molds

Mold pressure processing is an important part of mechanical manufacturing, and the level, quality and life of the mold are closely related to the mold surface strengthening technology. With the advancement of science and technology, various mold surface treatment technologies have made great progress in recent years. appears in:

1. The improvement of the traditional heat treatment process and its combination with other new processes; (Guide: How to improve the accuracy and quality of stamping die processing)

2. Surface modification technology, including carburizing, low-temperature thermal diffusion (various nitriding, carbonitriding, ion nitriding, ternary co-infiltration, etc.), salt bath thermal diffusion, boronizing, rare earth Surface strengthening, laser surface treatment and electric spark deposition cermet, etc.;

3. Coating technology and other aspects.

However, for die-casting molds with extremely harsh working conditions, the existing new surface treatment technology cannot meet the ever-increasing requirements. It can be expected that more advanced technologies are also expected to be applied to the surface treatment of die-casting molds. In view of the fact that surface treatment is one of the important means to increase the life of die-casting molds, surface treatment technology will play a pivotal role in improving the overall level of die-casting mold production in my country.
