The choice of material of auto part mould is crucial for the performance, durability, and final product quality and cost of the mould. Different materials have their unique characteristics and applications, so various factors need to be considered comprehensively when selecting them.
Auto part mould usually requires materials with high strength, high hardness, and excellent wear resistance. Therefore, high-quality steels such as P20, 718, H13 are commonly chosen. These steels possess good machinability and wear resistance, meeting the performance requirements of moulds under long-term and high-frequency usage.
he hardness and wear resistance of the steel determine the lifespan of the mould. Through processes such as heat treatment, the performance of the steel can be further enhanced to meet the specific injection moulding requirements of certain components.
Aluminum alloy materials for auto part mould also holds a certain market share. Aluminum alloys are characterized by low density, good thermal conductivity, and excellent machinability, making them suitable for manufacturing lightweight and high-precision moulds.
However, aluminum alloys have relatively poor hardness and wear resistance compared to steel, which limits their application range. Generally, aluminum alloy moulds are more suitable for producing small batches of high-precision auto parts.
In some specific application scenarios, such as the die head parts of plastic moulds for sale, plastic materials are also widely used. Plastic materials have the advantages of being lightweight and low-cost but are relatively poor in wear resistance and hardness.
Therefore, when choosing plastic materials, its application scenarios and performance requirements need to be fully considered to ensure that the selected materials can meet the usage needs of the mould.
In addition to steel, aluminum alloys, and plastics, there are also some non-metal materials used for making auto part mould, such as rubber and silicone. These materials are mainly used for making mould seals, suction cups, and other auxiliary parts.
When choosing materials for auto part mould, various factors such as performance, cost, and machining difficulty need to be comprehensively considered. At the same time, it is necessary to select the most suitable materials according to the specific application scenarios and requirements to ensure the quality and performance of the mould. In the future, with the development of technology and the continuous emergence of new materials, the material selection for auto part mould will become more diversified and refined.
