Raw Materials
Qualified steel wire sources, incoming inspection, and batch management support consistency from raw material to shipment.
Material sourcing and incoming inspection directly affect spring stability, especially when buyers require consistent fatigue life and force performance.
The material page summarizes source mills and batch management practices that support communication with buyers on spring steel selection.
Material Traceability Flow
Material sources are chosen around spring type, fatigue demand, surface requirement, and customer specification context.
Wire or strip condition, diameter or thickness, and certificate alignment are checked before production release.
Accepted material lots remain tied to production and inspection records rather than being mixed into anonymous stock.
Material choice is reviewed together with forming route, heat treatment, and validation requirements.
Material traceability stays visible through final inspection and shipment packaging where the program requires it.
