Product Description
Chaoyang precision dies are engineered for demanding applications across automotive, electronics, and industrial manufacturing sectors. Crafted from premium tool steel, our stamping dies ensure exceptional accuracy, long service life, and consistent reliability. From microelectronic components to large structural parts, our dies deliver precise forming, minimal burrs, and stable dimensions.
Advanced EDM, CNC grinding, and in-house heat treatment processes guarantee consistent performance throughout production. Beyond precision dies, Chaoyang also provides high-quality die sets and non-standard mould bases, enabling customers to integrate complete tooling solutions. For specialised requirements, our design team offers custom die kits tailored to your drawings, materials, and production needs, with professional support from the early development stage.
