Polishing and etching properties of tungsten carbide mold parts

    With the development of all industries, the mold industry this year is

also developing marvelously. Today, let us look at the introduction on

polishing and etching properties of tungsten carbide mold parts.
    From the widespread use of plastic mold, low surface roughness value is

very necessary. Low surface roughness value can affect the service life of

mold parts and the production efficiency and the quality of the products.

High surface quality can reduce corrosion, especially local pitting

corrosion, and reduce the risk of cracking. The chemical composition,

structure, hardness and carbide of polished steel must be evenly

distributed. Large carbide is extremely harmful on the surface polishing,

especially when they segregate into a strip.  It is particularly important

that steel can't contain oxide inclusions or segregation without large

deformation, so the smelting and deoxidation technology must be strictly

controlled. The effect of vacuum arc remelting and electroslag remelting is

good. This process has now become the main production mode of plastic mold

steels.
    If there is any hole not closed in the steel, it will affect the

polishing properties of tungsten carbide mold parts. So it is very necessary

to prevent metallurgical defects and keep the density of the organization in

the hot working, which can be achieved by modern forming technology. Defects

caused by heat treatment or surface hardening should avoid causing

decarburization with uneven hardness.
