About tool steel
Tool steel is used to create cold die, hot forging die, die casting mold steel.
Mold is a major manufacturing tool for manufacturing parts in machinery manufacturing, radio instrumentation, motors, appliances and other industrial sectors.
The quality of the mold directly affects the quality of the pressure processing technology, the precision of the product and the production cost. The quality and service life of the mold are mainly influenced by the mold material and the heat treatment, except for reasonable structural design and processing precision.
Tool steel can be broadly divided into: cold-rolled die steel, hot-rolled die steel and plastic mold steel three categories for forging, stamping, cutting type, die-casting and so on.
Due to the different uses of various molds and complicated working conditions, the steel for molds should have high hardness, strength, abrasion resistance, sufficient toughness and high hardenability and quenching according to the working conditions of the molds manufactured by the molds Hardness and other process properties.
Due to the different uses and complex working conditions, the performance requirements of the mold steel are also different.
About Plastic tool steel Bar
Due to the large variety of plastic, the requirements for plastic products are also very different, also made a variety of different performance requirements for the manufacture of plastic mold materials.
Therefore, many industrialized countries have formed a wide range of plastic mold steel series. Including carbon structural steel, carburized plastic mold steel, pre-hardened plastic mold steel, age-hardening plastic mold steel, corrosion-resistant plastic mold steel, easy-cutting plastic mold steel, the overall hardened plastic mold steel, martensitic Aging steel and mirror-polished plastic mold steel.
