Electropin uses Automatic Die Rolling, a cold-forming process in which wire raw material is shaped by dies without cutting or heating. This eliminates scrap, prevents tool dulling, and enables production of up to 5 pins per second. The process produces highly consistent pins from the first to the millionth part, across materials including lead-free brass and stainless steel.
