What determines the service life of die steel? Maybe many people don't know much about this kind of products. Here's a simple analysis for you. I hope that after the analysis of this article, you will also have a certain understanding of the service life of mold materials!

1.模具钢的表面处理

1. Surface treatment of die steel

模具钢的表面处理也很重要。渗氮可以提高钢的表面硬度，延长模具寿命;电镀可以对模具钢进行改性，对于一些需要高亮度和耐腐蚀性的塑料零件，电镀可以用来增强和改变钢的性能。

The surface treatment of die steel is also very important. Nitriding can improve the surface hardness of steel and prolong the service life of die; Electroplating can modify die steel. For some plastic parts that need high brightness and corrosion resistance, electroplating can be used to enhance and change the properties of steel.

2.模具的结构设计

2. Structural design of mould

成熟的模具结构不仅要考虑产品材料性能、收缩率、成型温度、弹性拉伸变形系数，还要考虑冷却水路径、开合速度等。合理的模具结构可以延长模具寿命，保证模具的顺利生产。提高了效率，降低了成本。

The mature die structure should not only consider the product material performance, shrinkage, forming temperature and elastic tensile deformation coefficient, but also consider the cooling water path, opening and closing speed, etc. Reasonable mold structure can prolong the service life of the mold and ensure the smooth production of the mold. The efficiency is improved and the cost is reduced.

3.模具钢的性能和质量

3. Performance and quality of die steel

钢材质量的决定性因素，选择合适的模具钢是

The decisive factor of steel quality is the selection of appropriate die steel

重要的。比如注塑材料不同，对应的模具钢材料也会不一样，比如对抛光和耐腐蚀性要求高;一般来说P20模具钢的寿命在30万左右，12738模具钢50万没问题，H13模具钢和12344模具钢一般在80万-100万以上，可以根据情况选择。这是决定塑料模具寿命重要的。

important. For example, if the injection molding materials are different, the corresponding die steel materials will be different, such as high requirements for polishing and corrosion resistance; Generally speaking, the service life of P20 die steel is about 300000, 12738 die steel is 500000, H13 die steel and 12344 die steel are generally more than 800000-1 million, which can be selected according to the situation. This is an important factor in determining the service life of plastic molds.
