Overview
Our Custom Progressive Die Stamping Metal High-Carbon Steel Clips for Professional Auto Parts are engineered for demanding automotive applications where repeatable spring force, dimensional stability, and long fatigue life are essential. Manufactured from premium high-carbon spring steels and produced on high-speed progressive stamping lines, these clips deliver consistent retention, vibration resistance, and corrosion-protected finishes suitable for engine compartments, body assemblies, electrical harnesses, and trim retention systems. We offer full OEM services from tooling design and prototyping to large-volume production with stringent automotive quality control.

Surface Treatment Options
- Zinc Plating (Clear / Black) — corrosion protection with selectable thickness and passivation.
- Phosphate Conversion (Iron / Manganese) — excellent paint adhesion and lubricity for forming.
- E-Coat / Powder Coat — durable corrosion and chemical resistance for exterior applications.
- Black Oxide — thin, low-friction finish for internal components.
- Selective Plating — apply premium coatings only to contact or mating areas to reduce cost.
Quality Assurance
We apply automotive-grade QA to guarantee clip performance and traceability:
- Dimensional verification via CMM and optical comparators.
- Spring force and contact pressure measured with calibrated force gauges and automated test rigs.
- Fatigue / cycle testing to validate life expectancy (custom cycles per customer spec).
- Salt spray (NSS/ASTM B117) and humidity corrosion testing on plated samples.
- Hardness and microstructure verification after heat treatment (Rockwell & metallography).
- 100% in-line visual inspection, SPC monitoring, full FAI/PPAP documentation on request.
Factory Capabilities
Our metal-stamping facility integrates: high-speed progressive stamping presses (15–300 ton range) and servo presses for precision forming; in-house tool & die engineering using CNC machining and wire EDM; automated coil feeding, multi-station progressive dies with coining and bending stations; controlled heat-treat furnaces with quench & temper cells; shot-peening and stress-relief lines; automated plating and e-coat lines; robotic part handling and final assembly stations. Inline metrology, SPC, and serialized lot traceability ensure consistent, high-volume output that meets OEM automotive standards.
