Raw materials are drawn to desired diameter sizes and cut into rod-shaped punching pin blanks of fixed lengths.
Blanks are straightened and heated to 800-1300°C for 2-5 minutes, followed by oil quenching and low-temperature tempering to achieve tip hardness of Hv590-800.
Punching pins are clamped and ground according to specific angular requirements for various needle bases.
Surface cleaning to remove oil, rust, and other contaminants.
Comprehensive quality inspection followed by packaging and warehousing of qualified products.
