Precision Metal Stamping Parts and Spring Assemblies

Metal elastic components designed for mechanism return, clamping, or conductive contact functions. These assemblies typically include helical compression springs and matching custom-shaped metal brackets. By leveraging the elastic deformation of materials to store energy, they provide stable return or holding forces in electronic devices, appliance switches, and mechanical systems.

The manufacturing process involves precision die stamping and automated wire forming. The bracket section requires strict control over bending angles and mounting hole tolerances to ensure accurate positioning during assembly. The spring section must maintain consistent coil counts and perpendicularity of ground ends to prevent skewed loading. For assembled units, attention is paid to the connection strength between the spring leaf and bracket, as well as overall flatness, to avoid fatigue fracture or plastic deformation during long-term reciprocating motion.

Leveraging our mature precision stamping and spring production lines, we offer one-stop services from mold development to mass production. Our production facilities are equipped with inspection devices such as Mitutoyo 2.5D video measuring systems to perform full or sampling inspections on critical dimensions, ensuring consistency across batches. We support non-standard customization based on drawings or samples. Materials include stainless steel, carbon steel, or phosphor bronze, with surface treatments such as zinc or nickel plating available according to operating conditions. Our processes comply with ISO 9001 and IATF 16949 quality management system requirements.
