What kind of steel is generally used to make injection molds?

Injection molds are one of the key tools for manufacturing industrial products. Among them, mold steel, as the main material for mold manufacturing, has a very important impact on the life, load-bearing capacity and surface quality of the mold.

 

 

There are many types of injection mold steel commonly used in the market. Below we will introduce some of the more common models and specifications in detail. (For reference only)

(1), P20:

P20 injection mold steel is a high-quality pre-hardened steel that is widely used in injection molding and other fields. It has good machinability, corrosion resistance and high hardness, and is suitable for manufacturing large, medium or small injection molds.

(2), 718:

718 injection mold steel is a nickel-chromium alloy steel with high wear resistance and strength. It is an ideal choice for manufacturing high-density and high-precision injection molds.

(3), S136:

S136 injection mold steel is a stainless steel material that is also widely used in injection mold manufacturing. It has excellent corrosion resistance and high hardness, and is very effective in producing high-quality smooth surface parts.

(4) S136H:

S136H injection mold steel is a plastic mold steel with outstanding production characteristics and excellent corrosion resistance. It has excellent corrosion resistance, less heat treatment deformation, and its maintenance cost and production cost are relatively low. Therefore, it is mainly suitable for high-polishing and high-requirement inner molds, high-corrosion-resistant plastic molds, production, medical, food industry and other products.

(5) H13:

H13 injection mold steel is a molybdenum steel material, suitable for manufacturing complex shape molds that require high wear resistance and impact resistance. It has good processing performance, high toughness and strength.

(6) NAK80:

NAK80 injection mold steel is a special alloy steel material with high hardness. Its advantages include corrosion resistance, high wear resistance and easy processing. It has very obvious advantages in manufacturing large injection molding molds.

(7) Buderus Edelstahl 1.2083

Buderus Edelstahl 1.2083 (German Buderus plastic mold steel 1.2083) is a high-quality stainless steel material that is often used to produce high-performance injection molds. It has good corrosion resistance and surface smoothness, and can obtain excellent hardness after proper heat treatment.

In short, the choice of injection mold steel should be based on personal needs and actual conditions. Each manufacturer has different processes, so the choice of steel is also different. The above only lists some common types of injection mold steel. Others such as SKD61, 2738, etc. are also widely used. At the same time, during use, it is also necessary to pay attention to the correct hardening process to ensure that the mold steel achieves better performance.
