Initially, tungsten carbide powder and cobalt powder are carefully selected and batched according to application requirements. These powders, once mixed, undergo thorough crushing and drying.

As the temperature gradually increases to 700-800°C, the bonding between particles strengthens but remains fragile. When the temperature reaches 900-1000°C, the gaps between particles reduce, and the bonding becomes more solid.

Carbide inserts, known for their exceptional hardness, wear resistance, and heat resistance, play a significant role in various industries. From woodworking machinery to the electronics industry, the applications of carbide inserts are wide and varied. This article briefly introduces the manufacturing process of carbide inserts, including the production process of the blade blanks and the precision finishing process of the blades.

The mixture of tungsten carbide and cobalt powders is pressed under high temperature and pressure. Initially, the metal particles are loosely connected and easily fractured.

At the sintering temperature of 1100-1300°C, the voids further decrease, and the bonding between particles becomes robust. Upon completion of sintering, the structure of the tungsten carbide blade consists of a cobalt base with tungsten carbide particles embedded, where different particle sizes and cobalt layer thickness determine the blade’s performance.
