Tungsten Carbide Rod Powder Extrusion Molding Existing Problems

Tungsten Carbide Rod Powder Extrusion Molding Existing Problems

Although our country has already had the ability to produce tungsten carbide rod itself, the species and quality or property is far away from other foreign countries. The reason is because the immaturity not only in knowledge but also in technology. First of all, the research and exploration for the binder is far away from the standard. The study on the mix principle of powder and binder is insufficient. The binder production technology is still highly confidential technology. There is no formal report about practical binder-making process. The application for the introducing technology is not enough, it maintains the level which can only satisfy the present producing requirement. Manufactures do not cooperate with each other to search for the best technology and overcome problems. Also the study on the basic theory stays on the surface, especially rheology theory in the powder extrusion molding processing.
