Introduction of Tungsten Steel Alloy Mould Process:
1. The tungsten steel round bar and other custom shaped products
adopts low-pressure sintering technology, and the quality is stable
and reliable: The high sintering pressure can reach 100 kg force,
and the internal pores of the carbides can be effectively
eliminated, so as to obtain a high-hardness and high-strength blank
with good densification. The advanced temperature control system
can Effectively reduce quality fluctuations.
2. With automatic pressure relief extrusion equipment, various
types of bars can be produced.
3. Fine-grind the bar material to achieve the mirror effect: the
use of CNC grinder can quickly remove the damage layer generated
during polishing, improve the surface finish, and achieve the
mirror effect. Precision grinding bar material: diameter tolerance
D≤±0.03 length tolerance L≤±0.5.
Production characteristics of cemented carbide molds:
1. Single piece, multiple production, tungsten steel alloy mold is
a long-life special process equipment, each mold can only produce a
certain shape, size and precision parts, which determines that the
mold production is a single piece, multiple varieties The nature of
production.
2. Mould processing is developing towards mechanization, precision
and automation
3. The mold production cycle is objectively required to be short.
At present, due to the acceleration of the upgrading of new
products and market competition, the mold production cycle is
objectively required to be shorter and shorter, and the production
management, design and process work of the mold should meet the
objective requirements.
4. The complete set of tungsten steel alloy mold production. When a
certain part requires multiple molds to process, each pair of molds
often involves and affects each other. Only the final product is
qualified, this set of molds is qualified. Therefore, this feature
must be fully considered in the production and planning
arrangements.
