Overview of Cemented Carbide Punching Needles

Cemented Carbide Punching Needles are made of round carbide rods finely ground and characterized by high precision, high hardness and good bending strength. Cemented carbide is a mixture of metal carbide powder (such as tungsten carbide, titanium carbide, niobium carbide and vanadium carbide, etc.) and cobalt, pressed by powder metallurgy, which is a material with high hardness and wear resistance, and can ensure that the workpiece has a certain degree of strength and toughness.

The hardness of Tungsten Carbide Needle Pin is usually very high, for example, the hardness can reach 92.0HRA, which makes it possible to keep the edge sharp and prolong the service life under high loads and high-speed stamping. As the carbide contains high hardness metal carbide, the punching needle has excellent wear resistance and can maintain shape and size stability over a long period of time.

Tungsten carbide pins are mainly used in the hardware and electromechanical processing industry, and are usually mounted on stamping molds as blanking tools to separate or plastically deform the material to obtain the desired parts. It is widely used in industrial machinery manufacturing and processing fields, such as automobile manufacturing, aerospace, electronics and electrical appliances.
