Product Name: High-Precision Automotive Connector Progressive Stamping Die
Parameters: Die dimensions: 800×600×450mm; blanking force: 80 tons; pitch accuracy: ±0.005mm; stamping speed: up to 200 strokes/min; applicable material thickness: 0.1–0.5mm.
Material: The punch and die inserts are made of imported SKD11 cold work die steel, guide components are made of SUJ2 bearing steel, and the die frame is cast from HT300 cast iron. This material combination offers high wear resistance and impact toughness.
Process: The die is machined using slow wire EDM and high-precision form grinding, followed by vacuum heat treatment and deep cryogenic treatment to relieve internal stress. Assembly involves precision benchwork fitting to ensure uniform cutting clearance. During the tryout phase, a high-speed press with an automatic feeder is used, and first-off parts are fully inspected on an optical projector, ensuring stamping burrs remain within 0.01mm. The die can achieve a service life of 120 million strokes, making it suitable for producing connector terminals for companies like TE Connectivity and Amphenol.
