Case

FIWOK METALWORKS, a Shenzhen contract precision manufacturer with 14+ years of industrial expertise, presents Case 021 covering custom Precision Step Punch Pins. The project utilized Swiss Turning (Sliding Headstock) to machine High-Carbon Tool Steel (AISI D2, heat-treated condition) specified for wear resistance into multi-stepped segments. This batch run of 5,000 Pieces met dimensional specs for linear deviation and runout mitigation. FIWOK maintains lot-based material traceability with mill test reports and batch quality documents. Certified third-party dimensional inspection and hardness reports are provided upon explicit engineering request to verify compliance for tooling constraints in high-wear stamping die applications.
