Plastic mold steel is a special type of steel used to make plastic molds. The choice of steel for plastic molds has an important impact on the quality and life of molds. Different plastic mold steels have different properties and application ranges. The following will introduce several common plastic mold steels and their properties.
P20 steel: P20 steel is a commonly used plastic mold steel with good cutting performance and heat treatment performance. It has high hardness and wear resistance, and is suitable for manufacturing small and medium-sized plastic molds. The advantage of P20 steel is that it is relatively low and has a wide range of applications.
2.718 steel: 718 steel is a high-quality plastic mold steel with high hardness and wear resistance. It has good heat treatment performance and corrosion resistance, and is suitable for manufacturing large and complex plastic molds. The advantage of 718 steel is that it has high strength and toughness, and is able to withstand large impact loads.
3.NAK80 Steel: NAK80 steel is a high-quality plastic mold steel with good cutting performance and heat treatment performance. It has high hardness and wear resistance, and is suitable for manufacturing plastic molds with high precision and high surface quality requirements. The advantage of NAK80 steel is that it has high corrosion resistance and heat resistance, and can maintain stable performance in high-temperature environments.
4.S136 steel: S136 steel is a high-quality stainless steel plastic mold steel with good cutting performance and heat treatment performance. It has high hardness and wear resistance, and is suitable for manufacturing plastic molds with high precision and high surface quality requirements. The advantage of S136 steel is that it has good corrosion resistance and heat resistance, and is able to maintain stable performance in wet and corrosive environments.
5.H13 steel: H13 steel is a high-quality hot work die steel with good heat resistance and wear resistance. It has high hardness and strength, and is suitable for manufacturing plastic molds in high-temperature environments. The advantage of H13 steel is that it has good heat resistance and wear resistance, and can maintain stable performance in high temperature and high pressure environments.
In general, the choice of plastic mold steel should be determined according to the specific mold requirements and use environment. Different plastic mold steels have different properties and application ranges, and choosing the right plastic mold steel can improve the quality and life of the mold and reduce the production cost. When choosing plastic mold steel, we should also take into account factors such as stability, stability and processing performance, and comprehensively consider the selection of the most suitable plastic mold steel.
