HR004 ST7 HR carbide High cobalt content, medium particle size, good wear resistance and good toughness







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.We provide engraving service and support customization, and samples will be prepared as your require.Cemented tungsten carbide cold heading dies for production bolt die
In addition to their exceptional performance, tungsten carbide bolt molds can be customized to meet specific production requirements. Whether it’s size, thread type or other specifications, molds can be customized to meet different bolt manufacturing needs, providing versatility and flexibility for different applications.Overall, tungsten carbide bolt molds are a testament to precision engineering, durability, and reliability. Its ability to consistently produce high-quality bolts to tight tolerances makes it an indispensable tool for fastener manufacturers looking to raise production standards and meet customer demands.

Our company has in-depth cooperation with well-known express delivery companies. DHL UPS delivers according to your needs.
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.
