Precision TIN Stamping Punch Pins Tungsten Carbide Punch Dies
Punch pins, also known as pins, are screw-formed tools primarily used to finish screw heads and create recess shapes in screws (including Phillips, Pozi, Hexagon, Square, and Six-lobe recess patterns). Manufactured from high-speed steel or carbide materials, our punch pins are renowned nationwide and available in various sizes to meet diverse application requirements.

Manufacturing Process
1. Drawing and Cutting
Tested raw materials are drawn to the desired diameter using a wire drawing machine, then cut into fixed-length rod-shaped punching pin blanks.
2. Heat Treatment
Punching blanks are first straightened on a platform with a dial gauge, then heated to 800-1300 degrees Celsius for 2-5 minutes in a high-frequency electric furnace or salt bath furnace. After oil quenching and hardening, tip hardness reaches Hv590-800, followed by low-temperature tempering treatment.
3. Grinding Processing
Punching pins are clamped on machine tool spring collets, with grinding forming processes performed according to specific angular requirements for various needle bases.
4. Polishing
Surface cleaning removes oil, rust, and other contaminants to prepare the pins for final inspection.
5. Inspection and Storage
Products undergo rigorous quality control inspection against required specifications before qualified items are packaged and stored.
