Cold Heading Dies

Cemented Carbide Dies: Precision Shaping with Square and carbide blanks round

Cemented carbide dies offer exceptional hardness, wear resistance, and strength, making them suitable for applications that involve high-pressure and abrasive conditions. They are commonly used in metalworking processes such as cold heading, wire drawing, extrusion, and stamping.

In cold heading, cemented carbide dies are utilized to shape metal blanks into desired shapes, such as screws, bolts, and fasteners. The hardness and toughness of the carbide material enable the dies to withstand the high forces and repeated impacts involved in the cold heading process, ensuring consistent and precise shaping of the metal.

In wire drawing, cemented carbide dies are used to reduce the diameter of metal wires while maintaining their strength and surface quality. The smooth and wear-resistant surface of the carbide dies allows for efficient and precise wire drawing operations, resulting in high-quality wires for various applications.

Cemented carbide dies also find applications in extrusion, where they are used to shape and form materials such as plastics, rubber, and metals. The superior hardness and wear resistance of the carbide dies enable them to withstand the extreme pressures and temperatures involved in the extrusion process, ensuring accurate and reliable shaping of the materials.
