high quality tungsten carbide GT55 ZHD82 cold heading die cemented carbide

Short Description:

tungsten carbide cold heading die are high hardness and strength alloy materials made by pressing and sintering using powder metallurgy methods, and are widely used in production and processing fields. Under the wear-resistant working condition of bearing impact or strong impact, the common property of cold heading die is that the cemented carbide is required to have good impact toughness, fracture toughness, fatigue strength, bending strength and good wear resistance.

Tungsten carbide cold heading die are specialized tools used in the manufacturing process of fasteners, such as screws, bolts, and rivets. These dies are made of carbide, a hard anddurable material that can withstand the high pressure and stress of the cold heading process. The cold heading process involves feeding a wire or bar stock into a machine that uses a die and punch set to shape and form the material into the desired shape of the fastener.

FAQ

Are the hexagonal heads of the screws protruded?
A: Most of them are made of piers, because this can save materials. Depending on the tonnage of the pier forging machine and the bolt diameter, cold pier or hot pier technology can be used.
02
Are the bolts entirely die cast?
A:If the bolt material is an alloy or metal with a low melting point such as aluminum alloy, zinc alloy, copper alloy, etc., die casting can also be used. Steel ones are not made by die casting.
03
