Precision Machining for Stamping & Cold Forming Tooling Components
We manufacture high-precision components for stamping dies, cold forming dies, molds, and tooling systems — including punches, inserts, mold bases, guide bushes, transfer fingers, and fixture components. With ±0.005mm precision capability, support for hardened tool steels (HRC 60+) and surface treatments like induction hardening and Tufftride, we support your tooling projects from prototype to production, covering both stamping and cold forming applications.
Stamping & Cold Forming Tooling Component Manufacturing Capabilities
We deliver high-quality custom-machined components for stamping dies, progressive dies, cold forming dies, and mold tooling systems — punches, inserts, mold plates, mold bases, guide bushes, transfer fingers, and fixture components. Every project follows our full quality-control workflow, from raw material incoming inspection through final dimensional verification. We machine a wide range of materials including tool steels, stainless steels, copper alloys — detailed material capabilities are listed below. With 3 CNC machining centers, wire EDM, surface grinders, and precision inspection equipment including Nikon projectors and TESA height gauges, we ensure consistent quality across every batch. No minimum order quantity — we treat every part with the same rigorous quality standards.
