Electropin uses Automatic Die Rolling, a cold-forming process that shapes pins without cutting or heating the raw material. This eliminates scrap, prevents tool dulling, and enables production of up to 5 pins per second. The result is consistent dimensional accuracy from the first pin to the millionth, with a defect rate of just 1 in 600,000,000.
