Jan 09, 2020
1. Improved technology of traditional heat treatment process;
2. Surface modification technology, including surface thermal expansion treatment, surface phase change strengthening, electric spark strengthening technology, etc.;
Third, coating technology, including electroless plating, etc.
Die-casting molds are a big category of molds. With the rapid development of my country's automobile and motorcycle industry, the die-casting industry has ushered in a new period of development. At the same time, higher requirements have been put forward for the comprehensive mechanical properties and life of die-casting molds. To meet the ever-increasing performance requirements, it is still difficult to meet the application of new mold materials alone. Various surface treatment technologies must be applied to the surface treatment of die-casting molds to meet the requirements for high efficiency, high precision and long life of die-casting molds. . Among various molds, the working conditions of die-casting molds are relatively harsh. Die casting is to fill the mold cavity with molten metal under high pressure and high speed and die-casting. It repeatedly contacts the hot metal during the working process. Therefore, the die-casting mold is required to have high thermal fatigue, thermal conductivity, wear resistance, and corrosion resistance. , Impact toughness, red hardness, good mold release, etc. Therefore, the surface treatment technology requirements for die casting molds are relatively high.
