模具是机械制造、无线电仪表、电机、电器等工业部门中制造零件的主要加工工具。模具的质量直接影响着压力加工工艺的质量、产品的精度和产量及生产成本,而模具的质量与使用寿命除了靠合理的结构设计和加工精度外,主要受模具材料和热处理的影响。模具材料是模具制造业的物质和技术基础,其中模具钢材是传统的模具材料,在模具材料中应用最广的当属模具钢材。其品种、规格、质量对模具的性能、使用寿命和制造周期起着决定性的作用。据《中国模具
Mold is a major manufacturing tool for manufacturing parts in machinery manufacturing, radio instrumentation, motors, appliances and other industrial sectors. Mold quality directly affects the quality of the pressure processing technology, product accuracy and production and production costs, and mold quality and service life in addition to rely on reasonable structural design and processing accuracy, mainly by the impact of mold materials and heat treatment. Mold material is the material and technical basis of the mold manufacturing industry, of which the mold steel is the traditional mold material, which is undoubtedly the most widely used mold steel in the mold material. Its variety, specifications, quality of mold performance, life and manufacturing cycle play a decisive role. According to "China mold
