steel for plastic mold

Introduction

Plastic mold steel is a kind of special steel for making plastic molds. Due to its special characteristics, it can be widely used in various industries such as automobile, engineering, electrical appliances, sanitary ware, and furniture. In addition, it can also be widely used in the manufacturing of plastic products, such as plastic combs, automobile parts, electrical appliance accessories and precision instruments.

Characteristics

Plastic mold steel is widely used for making plastic molds due to its special characteristics. First of all, it is a kind of cold-work die steel with good wear resistance and high compressive strength. Its hardness is up to HRC60, which is higher than that of general mold steel. Moreover, plastic mold steel has a good polishability and thermal conductivity, which are necessary to accelerate material ejection when the plastic molds are running. In order to reduce the production of scrap product, plastic mold steel also has an excellent resistance to the corrosion occured generated by the high temperature and pressure of the injection process. Finally, compared with general mold steel, plastic mold steel has a good surface finish, which is beneficial to reduce the surface defects of plastic products.

Applications

Plastic mold steel has a wide range of applications. It is mainly used for manufacturing various types of plastic products, such as electrical appliance accessories, automotive moldings, and sanitary ware. It can also be used for making metal moldings including precision instruments, locks and furniture parts. In addition, plastic mold steel can be used for the production of high-precision plastic molds such as instrument cases, water proof plastic shells, and lamp shads. The mold made with this steel has a long service life and high efficiency, which is beneficial to improve the production capacity.

Conclusion

In conclusion, plastic mold steel is a kind of special steel with excellent properties, which makes it suitable for a wide range of applications, such as the manufacture of plastic products, metal moldings and precision molds. It has high compressive strength and good wear resistance, which makes it beneficial to reduce the production of scrap product. In addition, it can also provide a good surface finish and thermal conductivity, which are necessary for improving the quality and efficiency of the plastic products. Therefore, plastic mold steel is an ideal material for the application of plastic molds.

Plastic mold steel is a kind of special steel specially used for making plastic mold. Its behavior in making plastic mold will be different from other steel grades. It can be said that plastic mold steel is the soul of plastic mold which determines the quality of plastic products to a large extent.

The plastic mold steel has good comprehensive mechanical properties, accurate hardenability and good polishability. Its wear resistance and corrosion resistance are also excellent. It has good cold plastic deformation, thermal plastic deformation and machinability. The plastic mold steel has the characteristics of low thermal conductivity, excellent thermal fatigue stability, relatively high thermal strength and good dimensional stability at high temperature.

Generally speaking, the main alloy elements of plastic mold steel are carbon, manganese, chromium, molybdenum and vanadium. Commonly used plastic mold steel grades are: 638 steel, Cr12, H13 and other high-speed tool steel. The hardenability of plastic mold steel is usually greater than HRC 50.

Plastic mold steel is widely used in the manufacture of plastic molds such as injection molds, extrusion molds, low pressure molds, blow molds and rubber molds. Plastic mold steel can effectively ensure that the plastic molded articles have a good surface finish and strength, durability and dimensional accuracy.
