Common Applications in Automotive Industry

  • Suspension Systems: Coil springs, leaf springs, stabilizer bars
  • Transmission & Clutch: Clutch diaphragm springs, shift fork springs
  • Seating & Interior: Seat adjustment springs, lumbar support springs
  • Engine & Valve Train: Valve springs, fuel injection springs
  • Braking Systems: Parking brake springs, brake pad retention clips
  • Electrical & Connectors: Battery contact springs, connector springs

Производственный процесс

  1. Material Selection – Prime steel coils sourced from ISO‑certified mills
  2. Холодная прокатка – Precision thickness reduction and width control
  3. Термическая обработка –
    • Отжиг: Spheroidize or bright annealing for formability
    • закалка & Закалка: Oil or molten salt quenching followed by tempering for strength and toughness
  4. Поверхность & Edge Treatment – Polishing, rounding, разрезание, decambering
  5. Quality Inspection – Chemistry analysis, hardness testing, flatness check, tensile test, metallographic examination
