cold heading die

Cold Heading Dies

• Used in the cold heading process, where metal is formed at room temperature.
• These dies shape wire or rod stock into fasteners like bolts, screws, and rivets by applying high pressure.
• Typically made from high-hardness materials like tungsten carbide or tool steels to withstand repeated high-stress impacts.

Punch Dies

• Part of a punching or stamping system, used to create holes or shapes in sheet metal.
• The punch (male part) presses into the die (female part) to cut or form the material.
• Often made from tool steel or carbide for durability and precision.

Trimming Dies

• Used to remove excess material (flashing) from a workpiece after forming operations like stamping, forging, or casting.
• Helps achieve the final part shape and smooth edges.
• Typically made from hardened tool steels or carbide for long life and precision trimming.

Flat Thread Rolling Dies

• Used in the thread rolling process to form external threads on fasteners or other components.
• Unlike cutting threads, thread rolling displaces the metal to form the thread, resulting in stronger threads.
• Flat dies are used in flat die thread rolling machines.
• Made from hardened tool steel or tungsten carbide for wear resistance.

Tungsten Carbide Dies

• Dies made from tungsten carbide, a very hard and wear-resistant material.
• Used in high-volume, high-precision applications where tool life and surface finish are critical.
• Commonly used in cold heading, thread rolling, and fine blanking operations
