Tungsten Carbide Dies are essential tooling components used in high-precision forming, cold heading, wire drawing, punching, and extrusion processes. Manufactured from premium Tungsten Carbide (WC), these dies offer exceptional hardness, superior wear resistance, and extended service life, making them the industry standard for producing fasteners, metal parts, rods, and tubes with high accuracy and efficiency.
What Are Tungsten Carbide Dies?
Tungsten Carbide Dies are shaping tools made from sintered tungsten carbide and cobalt binder. Compared to traditional steel dies, tungsten carbide provides higher compressive strength and better resistance to abrasion, making it ideal for heavy-duty, high-speed production environments.
These dies are commonly used in:
Wire Drawing
Nail & Screw Cold Heading
Bolt and Nut Forming
Extrusion and Stamping
