Technological process of production of our tungsten carbide cold heading dies: powder process → formula according to the use requirements → wet grinding → mixing → smash → dry → sieving → add binder → dry again → get the mixture after sieving → pelletize → pressing → forming → sinter-hip → forming (blank) → flaw detection → cylindrical grinding → packaging → entering warehouse.
Tungsten carbide cold heading dies is mainly used for stamping watch parts, strings for musical instruments, battery case, toothpaste tube, small size steel ball, screw, nut, etc., or used in the field of standard parts, bearings, tools, for stamping standard parts, bearings, tools, and even for stamping warhead and cartridge case.
Tungsten carbide cold heading die used in working conditions of under impact or strong impact and at the same time required wear-resisting, so the tungsten carbide cold heading die must has good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance. But generally speaking, the relationship between wear resistance and toughness of cemented carbide, is contradictory, when used, when choosing tungsten carbide grade, we should according to the machining object and working conditions to choose the right grade, to meet specific application requirements.
