Description
The custom stamped stainless steel contact spring is a precision elastic component designed for reliable electrical contact and mechanical resilience in electronic and electrical assemblies. Manufactured using high-accuracy metal stamping processes, this contact spring offers consistent shape, stable contact force, and long service life.
Stainless steel material provides excellent corrosion resistance, fatigue strength, and dimensional stability, making the contact spring suitable for environments with frequent insertion cycles, vibration, and temperature variation. The elastic structure ensures stable electrical conductivity while maintaining reliable contact performance over repeated use.
The contact spring can be customized in thickness, shape, bending angle, and contact point design to meet specific electrical and mechanical requirements. Additional surface treatments or partial plating can be applied when enhanced conductivity or wear resistance is required.
Widely used in connectors, battery contacts, terminals, switches, and electronic modules, this stamped stainless steel contact spring supports OEM and ODM projects based on customer drawings or samples, ensuring consistent quality and scalable production.

Dongguan Kaiyan Hardware Products Co., Ltd. is a professional manufacturer specializing in precision metal stamping and formed electrical contact components. With years of manufacturing experience, we provide stable, reliable, and cost-effective metal solutions for global customers.
We focus on the production of electrical contacts, terminals, spring contacts, conductive tabs, and shielding components. Advanced stamping and bending processes ensure high dimensional accuracy, consistent performance, and suitability for automated assembly.
Kaiyan works with phosphor bronze, brass, stainless steel, and other metal materials to meet different requirements for conductivity, elasticity, strength, and durability across various applications.
We offer multiple surface treatments, including nickel plating, tin plating, zinc plating, silver plating, and gold plating. These finishes improve corrosion resistance, solderability, wear resistance, and long-term contact reliability.
From design evaluation and tooling development to sample production and mass manufacturing, we provide one-stop OEM and ODM services. Custom dimensions, structures, and performance specifications are supported.
Quality is strictly controlled throughout material inspection, in-process monitoring, and final inspection to ensure consistent quality and reliable electrical performance.
With extensive export experience, we understand European and American market standards and purchasing requirements. Stable production capacity, clear communication, and on-time delivery help reduce sourcing risks and accelerate time to market.
We specialize in custom metal stamping parts, deep drawn components, metal brackets, clips, terminals, shielding parts, and precision hardware for industrial and electronic applications.
We commonly work with stainless steel, aluminum, carbon steel, brass, copper, phosphor bronze, and galvanized steel. Material selection can be customized based on application requirements.
Yes. We provide full OEM and ODM services, including design support, tooling development, prototyping, and mass production based on drawings or samples.
Our core processes include metal stamping, deep drawing, bending, piercing, rolling edge forming, tapping, welding, and surface finishing.
Available surface treatments include zinc plating, nickel plating, tin plating, anodizing, powder coating, painting, polishing, and passivation.
Depending on part design and material, our standard tolerance ranges from ±0.05 mm to ±0.1 mm. Tighter tolerances can be achieved for precision components.
MOQ depends on product complexity and material. For custom stamped parts, MOQ is flexible and can be discussed during quotation.
Tooling usually takes 10–20 working days. Samples are typically available within 7–10 days after tooling completion.
We follow strict quality control procedures including incoming material inspection, in-process checks, and final inspection. Quality documentation can be provided upon request.
Our products are widely used in electronics, electrical equipment, automotive components, industrial machinery, thermal management, and consumer hardware.
