What are the types of injection mold materials?

Injection mold is an important tool for the production of plastic products, and the choice of its material has an important impact on the performance and life of the mold.

The following are common types of injection mold materials:

(1) Tool Steel: Tool steel is one of the most commonly used injection mold materials, with excellent mechanical properties and wear resistance. Common tool steels include P20 steel, 718 steel, NAK80 steel and other steels. These tool steels have high hardness, strength and wear resistance and are suitable for the production of large quantities of plastic products.

(2) Stainless Steel: Stainless steel is a corrosion-resistant material with good acid and alkali resistance and high temperature resistance. Common stainless steel materials are S136, 420 and so on. Stainless steel mold has high corrosion resistance and surface finish, which is suitable for the production of plastic products with high surface quality requirements.

(3) Aluminum Alloy: Aluminum alloy is a lightweight, good thermal conductivity material, commonly used aluminum alloy 7075, 6061 and so on. Aluminum alloy mold has low density and good thermal conductivity, suitable for the production of large, thin-walled plastic products.

(4) Copper Alloy: Copper alloy has good thermal and electrical conductivity, and common copper alloys are H13, H11 and so on. Copper alloy mold has high thermal conductivity and wear resistance, which is suitable for the production of plastic products with high dimensional accuracy and surface quality requirements.

(5) High-temperature Alloy: high-temperature alloy is a kind of material that can maintain stable properties in High Temperature environment, common high-temperature alloys are Inconel, Hastelloy and so on. The high-temperature alloy mold has high heat resistance and corrosion resistance, and is suitable for the production of high-temperature plastics or plastic products with special process requirements.

Please note that the above are common types of materials for injection molds, and the specific choice needs to be judged according to the actual situation. If you have specific needs or more detailed questions, it is recommended to consult a professional mold manufacturer or engineer for accurate advice and guidance.
