What Types of Injection Mold Materials are there?

 

Injection molds are important tools for producing plastic products. The choice of materials has an important impact on the performance and life of the molds.

 

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 producing 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 include S136, 420, etc. Stainless steel molds have high corrosion resistance and surface finish, and are suitable for producing plastic products with high requirements for product surface quality.

 

 

(3) Aluminum alloy: Aluminum alloy is a lightweight material with good thermal conductivity. Commonly used aluminum alloys include 7075, 6061, etc. Aluminum alloy molds have low density and good thermal conductivity, and are suitable for the production of large, thin-walled plastic products.

 

(4) Copper alloy: Copper alloy has good thermal conductivity and electrical conductivity. Common copper alloys include H13, H11, etc. Copper alloy molds have high thermal conductivity and wear resistance, and are suitable for the production of plastic products with high requirements for product dimensional accuracy and surface quality.

 

(5) High-temperature alloy: High-temperature alloy is a material that can maintain stable performance in high-temperature environments. Common high-temperature alloys include Inconel, Hastelloy, etc. High-temperature alloy molds have high heat resistance and corrosion resistance, and are 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 selection needs to be judged based on actual conditions. 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.
