Plastic mold which is commonly used 5 kinds of steel?

Plastic mold is a key tool for the manufacture of plastic products, usually requires the use of high strength, high hardness, high wear resistance and high processing difficulty of steel to meet its production requirements.

The following are 5 types of steel commonly used in plastic molds and how to distinguish them:

(1) P20 steel
P20 steel is a kind of low alloy steel with excellent machinability and weldability, which is widely used in plastic mold manufacturing. Its specific characteristics include good toughness, high hardness, wear resistance, easy processing, etc., suitable for manufacturing different types of injection products.

(2) 718 steel
718 steel is a high strength, high hardness and high thermal conductivity of the steel, while it also guarantees stable performance at high temperatures, and has a strong resistance to corrosion. The steel has a good development prospect in the manufacture of automobile parts, home appliance shell and other fields.

(3) H13 steel
H13 steel is a common steel suitable for a variety of molding products, which is characterized by high strength, good heat resistance, excellent toughness, and does not appear deformation and surface hardness degradation and other problems. H13 steel is suitable for the manufacture of injection molding molds with high requirements.

(4) S136 steel
S136 steel is a high-quality stainless steel widely used in plastic mold manufacturing. It is characterized by high hardness, good corrosion resistance and wear resistance, high precision and good thermal stability. S136 steel is commonly used in the manufacture of injection molding products such as various electronic product housings, auto parts, toys, etc.

(5) NAK80 steel
NAK80 steel is a high-strength, high-hardness steel with good wear resistance and corrosion resistance, especially suitable for mold manufacturing requiring high precision and long life. The steel is widely used in industries such as home appliances, automobiles, medical devices and toys.

The above are five kinds of steel commonly used in plastic molds, which have better application effects in engineering practice, and other suitable steels can be selected according to specific production needs.
