It is a high-tech enterprise specializing in R&D, production, and sales of high-quality cemented carbide materials. We have technical production engineers with more than 20 years of working experience, and professional marketing engineers and production management backbone teams.
Tungsten Carbide rectangle strips or flat blanks are usually used as very important accessories for woodworking knives. In order to meet the real-time changing pattern requirements of the market, tool manufacturers need to use wire cutting or grinding wheels to grind the standard carbide blanks into specific nonstandard shapes, and then weld them on the steel substrate of the woodworking cutter to finish the milling, grooving, planing works
Due to the long size of carbide blanks, the raw powder should be uniform during the pressing and forming process. We use a 315t overweight automatic pressing machine. After sintering, it must ensure there is no porosity inside, which is the most common cause of broken issues, We do the HIP sintering once again for all grades of tungsten carbide blanks to improve the crack-resistant quality. Due to the difficult complicated process of TCT woodworking cutters, like big welding areas 、simple welding, and grinding equipment, most TCT cutter makers, have strict demand for carbide strips with excellent crack resistance and good wear resistance. And following grades are popular accepted by the market
