Tungsten Carbide Bar’s Rising Demand

In recent years, the domestic production of tungsten carbide bar has been growing, but with the growing demand, the market demand outstrips supply, the demand for quality inspection is also facing difficulties. Detection of domestic tungsten carbide bar is commonly manual, it consumes more labor power, and the test result is unstable, thus automated testing equipment gradually is more favored by the majority of manufacturers.

According to related statistics, tungsten carbide bar includes high hardness, high wear resistance, high strength, and resistance to bending, long tool life and a series of excellent performance. Tungsten carbide bar is the blank material of producing drill and cutting tool, at present, it mainly adopts powder extrusion molding process. It is now widely used in producing drill, automotive tools, printed circuit board tool, engine tool, solid end mills, the overall reamer, chisel, etc., but also in producing the punch, mandrel, top and punch tool.

With the surge in market demand, the ultra-fine grain tungsten carbide bar has been more and more widely used. In the field of high-speed cutting tool, due to the high standards of safety, reliability and durability, internal and surface quality requirements of overall tungsten carbide cutting tools are more stringent. However, with the quality of tungsten carbide bar especially the ultrafine carbide is improving continuously, the quality of the surface of overall tungsten carbide cutting tools is more and more being taken seriously.
