A qualified precision contact spring is defined by three core metrics: elastic consistency, contact resistance, and fatigue life.Fabricated from high-purity elastic copper strips via precision stamping and targeted heat treatment, it delivers an elastic recovery rate of over 98%. The contact surface features controllable finish, guaranteeing stable contact resistance and uninterrupted signal conduction.Full-range inspections covering salt spray resistance, high & low temperature endurance, and insertion-extraction cycle life are performed, making our springs adaptable to rigorous scenarios including consumer electronics, new energy, industrial control, and medical equipment.We focus on custom precision metal stamping solutions, offering tooling and manufacturing services for non-standard, custom-shaped springs based on your drawings, with stable and reliable lead times.
