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.模具鋼的表面處理

1. Surface treatment of die steel

模具鋼的表面處理也很重要。滲氮可以提高鋼的表面硬度，延長模具壽命;電鍍可以對模具鋼進行改性，對于一些需要高亮度和耐腐蝕性的塑料零件，電鍍可以用來增強和改變鋼的性能。

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.模具的結構設計

2. Structural design of mould

成熟的模具結構不僅要考慮產品材料性能、收縮率、成型溫度、彈性拉伸變形系數，還要考慮冷卻水路徑、開合速度等。合理的模具結構可以延長模具壽命，保證模具的順利生產。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.模具鋼的性能和質量

3. Performance and quality of die steel

鋼材質量的決定性因素，選擇合適的模具鋼是

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

重要的。比如注塑材料不同，對應的模具鋼材料也會不一樣，比如對拋光和耐腐蝕性要求高;一般來說P20模具鋼的壽命在30萬左右，12738模具鋼50萬沒問題，H13模具鋼和12344模具鋼一般在80萬-100萬以上，可以根據情況選擇。這是決定塑料模具壽命重要的。

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.
