Custom die casting mold is the main category in the mold. With the progress of the times, the die-casting industry has ushered in a new era, with rapid development in industries such as automobiles, home furnishings, and telecommunications. At present, various industries have higher and higher requirements for the appearance processing of die cast tooling, and must achieve the functions of high precision, long life and high efficiency of die casting molds. This is also a proof of production capacity for professional die casting mold makers.
According to the process of repeating the task of forging and hot metal contact, the molten metal is under high pressure and high-speed die-casting molding cavity is filled. Therefore, die-casting molds with high heat loss, thermal conductivity and wear resistance are required, corrosion resistance, impact toughness, red hardness, excellent The demoulding and so on. Therefore, the appearance processing skills of die casting molds are relatively high. In recent years, various die cast tooling have appeared from time to time in appearance processing techniques, but they can generally be divided into three categories:
1) Improve skills in the traditional heat treatment process;
2) Appearance modification skills, including the appearance of thermal diffusion treatment, and the appearance of phase change to strengthen spark enhancement skills;
3) Electroplating skills, including electroless plating, etc.
The traditional heat treatment process of custom die casting mold is quenching-tempering for future appearance processing capabilities. Various information can be used as pressure die casting mould, the difference between the difference between the information of the divergence event and the result of the same appearance processing skills and technology. Markov compares the difference between the mold substrate processing skills and the traditional process based on the appearance mold data of the substrate pre-processing skills, history, processing technology, improving mold functions, and gradually mold life. Another skill is to improve the development of bias heat treatment with the use of traditional heat treatment technology and advanced treatment process appearance and advancement of die-casting die life. The method of carbon and nitrogen infiltration treatment of chemical heat treatment, and the practical quenching and tempering process connect the NQN part (that is, the infiltration of carbon and nitrogen-quenching-carbonitriding) composite strengthening, not only the appearance of hardness, but also a useful hardening layer Depth, additional layer hardness gradient diffusion is reasonable, tempering invariance and corrosion resistance are improved, and then custom die casting mold to obtain the appearance of excellent core parts, major advances in quality and function.
