Introduction for Shenzhen MIM Injection Molding Carbide

About introduction for Shenzhen MIM injection molding carbide  :  since the early 1920s invented by a German scientist, with name "widia" (like diamond) on market, carbide achieved widely application in industries as the first production of tungsten tensile mould and replaced expensive diamond tensile mould. In recent years development situation, the researching and designing theory of MIM injection molding carbide became much deeper and more science, applied more widely.

In the development of new carbide materials, iron-nickel-generation drill was quite popular a few years ago. For example, Shenzhen carbide material institute developed high strength and toughness carbide alloy equaling to YG, YG20, YG25 , received good results for cold heading die and cold extrusion die. Shenzhen Carbide Institute also developed a carbide die material equaling to YG (15-20) by method iron-nickel-generation drill. For roll forging standard parts and cold heading steel ball, it respects same effect as YG20

In recent years, popular new researches are fine crystal, ultra-fine grain, even nanocrystal cemented carbide and gradient cemented carbide. Gradient cemented carbide divided into composition gradient, and organization structure gradient. In addition, it also uses molten metal infiltration process to produce gradient cemented carbide, such as gradient carbide anvil.

Fine-grained and ultrafine grain cemented carbide has also been available, such as when drawing <φ lmm wire, fine grain YGS drawing die is three times of the normal drawing mode. In addition, there are cast-inlaid carbide hot die, achieving good results in terms of rolling and wire rod rolling.
