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.
