Description
Our Custom U-Shaped Wire Forming Spring Clips are engineered for reliable retention, resilient spring force, and long-term dimensional stability in demanding industrial, automotive, and electronics assemblies. Manufactured from premium spring steels and copper alloys using CNC wire forming, progressive stamping, precision bending, and controlled heat-treat processes, our clips deliver repeatable spring rates, tight tolerances, and superior fatigue life. Typical applications include cable management, hose clamps, battery retainers, EMI grounding clips, and precision fastening in machinery and vehicle systems. We offer end-to-end OEM services from rapid prototyping and toolmaking to high-volume production and aftermarket supply.

Key Advantages
- High fatigue resistance and consistent spring force over lifecycle.
- Tight dimensional control for precision mating and repeatable assembly.
- Wide material choice for conductivity, corrosion resistance, and mechanical strength.
- Flexible production scale — from rapid prototypes to high-volume automated runs.
Typical Production & Process Capabilities
- Material Procurement & Prep — Certified spring wires and strip stocked to customer spec; pre-cleaning and spool handling to avoid contamination.
- CNC Wire Forming & Progressive Stamping — Multi-axis CNC formers and high-speed progressive dies produce complex U-shapes, hooks, and formed features with consistent geometry.
- Secondary Operations — Laser trimming, coining, bending, flaring, swaging, and insert overmolding where required.
- Heat Treatment & Stress Relief — Controlled hardening, tempering, and stress-relief cycles to set spring properties and minimize relaxation.
- Surface Treatments — Electroplating (zinc, tin, nickel), passivation for stainless steels, black oxide, or custom coatings for wear and corrosion resistance.
- Finishing & Assembly — Deburring, tumble/shot peening for fatigue life, ultrasonic cleaning, and automated assembly into subcomponents.
- Testing & Inspection — Spring rate testing, tensile/yield verification, dimensional inspection (CMM/optical), salt spray corrosion tests, and lifecycle fatigue testing.
Surface Treatment & Coating Options
- Zinc / Clear Chromate — Cost-effective corrosion protection.
- Nickel Plating — Durable, wear-resistant conductive finish.
- Tin Plating — Excellent solderability for electrical contacts.
- Passivation (Nitric/Citric) — Improves stainless steel corrosion resistance.
- Black Oxide — Minimal dimensional change with cosmetic finish.
- Custom Specialty Coatings — PTFE, DLC, or epoxy for specific friction or chemical resistance requirements.
Quality Assurance
We implement a full quality program: incoming material certification, first-article inspection (FAI), in-process SPC monitoring, and 100% final inspection where required. Equipment includes CMM, optical comparators, force gauges for spring testing, salt spray chambers, and automated vision systems. Full lot traceability and PPAP documentation available for automotive customers.
