The extrusion process of tungsten carbide is affected by various parameters, among which extrusion temperature and extrusion speed are the two key factors.

Siphon degreasing in extrusion injection molding is a new degreasing process. Because of its fast degreasing speed and free from the influence of debinding atmosphere, it has become a hot spot in the research of tungsten carbide degreasing process.

Tungsten carbide rods have been widely used in various fields due to their special corrosion resistance, high hardness, excellent fracture toughness and compressive strength. With the development of science and technology, molding technology has developed from isostatic cool pressing and mould pressing to more modern and economic extrusion process.

Tungsten trioxide (WO₃) is a product of tungstate or calcining ammonium paratungstate, is an important intermediate compound of high purity tungsten.
