1. Requirements for injection moulding materials
Different plastics should use different steel materials, such as requirements for high polishing, corrosion resistance, etc.
2. Price
Steel used is not the more expensive the better. Considering cost of mold, mold steel should use material corresponding to life of mold to avoid unnecessary waste; life of general P20 material is about 300,000; 2738 materials are no problem at 500,000, H13/2344 is usually more than 80-100 million, and it can be selected according to actual situation;
3. Surface treatment
Surface treatment of mold is also very important. Nitriding can enhance surface hardness of steel and effectively extend life of mold. Electroplating can effectively modify mold steel. For some high-brightness and corrosion-resistant plastic mold parts, electroplating can be used to enhance and improve performance of steel.
