Special-Shaped Punches
However Complex the Profile, We Make It Precise and Stable!

A 20-year custom cold-heading shop for special needs no other supplier can handle. Micron-level accuracy with ±0.002 mm tolerance control, burr-free edges and one-pass forming of irregular workpieces. Full shape coverage: spline, internal octagon, special radii — any complex contour can be machined.

Open & Close Dies
Our In-House Core Technology — Complex Parts Cold Headed in One Step!

A 20-year die maker with one of China's leading open-and-close die processes, breaking the bottleneck of special-shaped forming. No secondary machining: double flanges, stepped special parts and other complex workpieces are cold headed in a single step, lifting efficiency by 50%. Lower consumable cost: segmented construction lets you replace only the worn segment instead of scrapping the whole die — consumable cost down 40%. More stable production: optimised stress distribution solves corner chipping and sticking so your line never stops. Fully customisable for multi-station cold headers — dedicated tooling for your special parts.
