Our custom curved stainless steel spring contact clips are precision elastic conductive hardware parts designed for electronic internal signal and power connection. Manufactured from premium 0.15mm thick 304 stainless steel raw material, every spring clip is shaped via high-speed precision stamping equipment to maintain consistent elastic curvature and strict dimensional uniformity.
After stamping forming, all workpieces go through full vibration grinding to eliminate sharp edge burrs completely, followed by nickel electroplating surface treatment to enhance oxidation resistance, anti-rust capacity, electrical conductivity and stable elastic fatigue resistance. Each standard spring clip features a curved elastic structure with two 3.0mm diameter circular mounting holes for easy screw fixing and assembly.
As an experienced OEM manufacturer offering all-round custom service, we can adjust sheet thickness, overall dimensions, hole sizes, curved radian, plating thickness and elastic force fully according to customers’ CAD engineering drawings or physical samples, perfectly matching the elastic connection demands of diverse electronic equipment.

Custom Services
As a professional OEM custom precision metal stamping manufacturer, we deliver comprehensive custom service for 304 stainless steel spring contact clips and electronic elastic conductive pieces:
Drawing & Sample Customization: Accept customer CAD engineering drawings or physical samples to develop exclusive custom spring clip products
Material & Thickness Customization: Adjust stainless steel sheet thickness (standard 0.15mm, customized thickness available), provide alternative stainless steel grades upon request
Surface Treatment Customization: Modify nickel plating thickness, provide alternative surface finishing solutions
Batch Order Customization: Support small trial sample batches and large-volume mass production orders
Secondary Machining Customization: Add tapping, bending, embossing and other secondary processing procedures as required
Product Advantages
Solve elastic fatigue failure issues: Premium 304 stainless steel base material maintains stable rebound force after thousands of compressions, avoids spring loosening and poor contact
Eliminate sharp burr assembly risks: Complete vibration grinding deburring removes all edge burrs, prevents scratches on circuit boards and battery shells during manual or automatic assembly
Fix unstable conductivity troubles: Uniform nickel plating blocks surface oxidation, ensures continuous stable current and signal transmission without intermittent disconnection
Resist short service life problems: Nickel plating anti-corrosion layer prevents rust in damp electronic working environments, greatly extending product service cycle
Remove dimensional inconsistency troubles: Precision stamping with ±0.015mm tolerance guarantees identical size and elastic radian across all finished spring clips, fully compatible with automated assembly production lines
Lower custom production barriers: Flexible OEM custom service adapts to exclusive electronic equipment structural designs, adjustable thickness, hole and curvature parameters, no need for clients to revise their product design plans
Quality Control
Incoming Raw Material Inspection: Full material composition and hardness testing for all incoming 0.15mm 304 stainless steel sheets to meet standard requirements
In-Production Dimensional Monitoring: Automatic digital caliper testing during stamping to check thickness, length, width and hole size, keep all dimensions within ±0.015mm tolerance
Burr Completeness Inspection: Full visual and tactile check after vibration grinding to ensure zero residual edge burrs
Nickel Plating Quality Testing: Plating thickness measurement and coating adhesion test to prevent plating peeling and shedding
Elastic Performance Verification: Cyclic compression fatigue test to confirm stable rebound force without permanent deformation
Final Finished Goods Inspection: Random sampling conductivity testing, appearance screening and full dimensional recheck before packaging and delivery
Batch Quality Traceability: Complete production and inspection records preserved for every production batch to support full quality traceability
