Wear-Resistant Aluminum Alloy Punching Die For Sheet Components

The aluminum alloy punching die runs in a high-speed coil-fed press. Aluminum strip advances, pauses, and the punches come down. Because aluminum can gall and stick, we coat the punch tips with a low-friction layer. This prevents material build-up, so the first hole and the thousandth hole measure the same diameter.

All die plates are surface-ground and fitted with low-friction guide bushings. The precise alignment protects small punches from chipping when the hole pattern is dense. Operators only need to keep a light oil film on the incoming sheet. There is no messy heavy grease, which helps keep the work area safer and cleaner.

Suitable for sheet up to three millimeters thick, this punching die works on presses from 30 to 80 tons. Interchangeable punch and die inserts allow different hole configurations on the same die shoe. It gives aluminum component suppliers a reliable way to maintain high machine uptime and avoid frequent stoppages caused by sticky residue on the punches.
