What material is used in injection mold manufacturing
2024-01-02
plastic Injection molding are complex tools composed of multiple parts, which play an important role in determining the quality and output of plastic injection products. Therefore, the selection of materials for injection mold processing is crucial, and the appropriate materials must be selected for processing according to the specific requirements of the mold and the characteristics of the plastic injection product production. Steel material Steel material is the most commonly used material in injection mold processing, because of its high hardness, high strength, good cutting performance, so it is very suitable for processing injection molds. Among the steel materials, P20 steel, 718 steel, NAK80 steel, S136 steel and so on are commonly used injection mold processing materials. (1) P20 steel: P20 steel is a high-quality low alloy cold work mold steel, usually used to produce medium size and medium weight plastic injection mold. The material has high hardness, good processing performance and good heat treatment performance, and is suitable for injection mold processing with high requirements. 
(2) 718 steel: 718 steel is a nickel-based alloy steel with high hardness, corrosion resistance and thermal stability. Because 718 steel has excellent wear resistance and high temperature strength, it is suitable for the production of high demand plasitc injection molding. (3) NAK80 steel: NAK80 steel is a high-strength, high-toughness steel material, with good thermal fatigue resistance and cold fatigue resistance. NAK80 steel is suitable for the production of high-speed injection molds and high-precision plasitc injection mould. 
(4) S136 steel: S136 steel is a high-quality stainless steel, with excellent corrosion resistance, high hardness and high wear resistance. Due to its good processability and stability, S136 steel is commonly used in the production of high-quality, high-precision injection mold.
