15-year precision mould making

    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.
