What are the types of plastic mold materials?

Plastic mold material is the raw material used to make plastic mold, which directly affects the production efficiency and quality of plastic products. According to different application fields, requirements and cost factors, commonly used plastic mold materials include the following types:

1. Silicone rubber
Silicone rubber is a high-quality mold material, which is characterized by high temperature resistance, not easy to age, and has good elasticity and flexibility. Therefore, silicone rubber is suitable for injection molds that need to be frequently processed at high temperatures.

2, Polyimide (PAI)
Polyimide is a high quality polymer material, which is characterized by good thermal stability, chemical and mechanical properties, but also has excellent wear resistance, impact resistance. This material is suitable for molds that need to produce high precision and long life.

3. Polyamide (PA)
Polyamide is a high quality polymer material, which is characterized by lightness and flexibility, but also has high strength and hardness. Due to its balanced properties, this material is suitable for the production of molds for various plastic products.

4, Thermoplastic polyamide (TPI)
Thermoplastic polyamide is a kind of high temperature and high performance plastic mold material, which is characterized by high temperature resistance, anti-pollution, excellent mechanical and chemical stability. The material is widely used in manufacturing in areas such as the automotive and aerospace industries.

5. Steel
Steel is one of the commonly used mold materials. It is widely used in injection mold manufacturing because of its high hardness, good wear resistance and high molding accuracy. Different types of steel are suitable for different injection molding products, such as P20 steel is suitable for the production of medium hardness plastic products.

The above several are common types of plastic mold materials, and each type has its own characteristics and advantages in different application fields and requirements. According to the specific needs, choose the right mold material, in order to produce more satisfactory plastic products.
