Precision‑Stamped Battery Contacts & Spring Components for Reliable Connections
We manufacture a comprehensive range of stamped metal contacts and spring components engineered for reliable electrical conductivity, stable contact force, and long operational life – even under repeated mating cycles or harsh environments.
Our product portfolio covers:
Battery Spring Contacts & Terminals – Customizable for battery holders, remote controls, portable devices, and power connection systems.
Brass & Copper Conductive Contacts – High‑conductivity materials ensuring low resistance and excellent current‑carrying capacity.
Stainless Steel Spring Clips – Durable and fatigue‑resistant, ideal for applications requiring frequent flexing and consistent pressure.
Custom Metal Clips & Retainers – Including V‑clips, U‑clips, retaining rings, and other stamped hardware made to your exact geometry.
Every part can be fully tailored in: material grade, dimensions and tolerances, spring force characteristics, surface finish (nickel, tin, gold, zinc plating, polishing, passivation), and operating environment requirements. We support both prototype development and high‑volume OEM production with fast turnaround.

DFM (Design for Manufacturing) Analysis – Our engineers optimize the design for stamping feasibility and cost.
Tooling Design & Fabrication – We build precision dies in‑house, tailored to your part geometry.
Prototype Sampling – We produce first‑article samples for your approval before mass production.
High‑Volume Stamping – Using progressive or transfer dies, we achieve high efficiency and consistent quality.
Quality Inspection – Dimensional, visual, and functional checks are performed throughout production.
Packaging & Export Shipment – We ensure secure packaging and timely delivery to your destination.
We accept drawings in PDF, DWG, DXF, STEP, and IGES formats, as well as physical samples for reverse engineering.
Materials & Surface Finishes – Tailored to Your Application
Choosing the right material and surface treatment is critical for performance. We offer a wide selection to match your electrical, mechanical, and environmental requirements.
Common materials we work with:
Brass / Copper – Excellent electrical conductivity, ideal for battery contacts and conductive terminals.
Stainless Steel (AISI 301) – High elasticity and corrosion resistance, perfect for spring clips and repeated‑flex applications.
Carbon Steel / Spring Steel – Cost‑effective solution for structural clips, retainers, and general hardware.
Surface finishing options:
Nickel plating – general protection and solderability.
Tin plating – good conductivity and corrosion resistance.
Gold plating – high‑end applications requiring low contact resistance.
Zinc plating – economical rust protection.
Polishing – bright and smooth surface finish.
Passivation – enhances corrosion resistance on stainless steel.
Our engineering team can recommend the optimum material and finish combination based on your operating environment, cost targets, and lifespan requirements.
Applications Across Key Industries
Our precision stamped components are widely deployed in:
Consumer Electronics – Battery holders, remote controls, smart home devices, wearables, and sensors.
New Energy & Battery Systems – Lithium‑battery connection terminals, busbars, battery module hardware, and power distribution components.
Automotive Electronics – Electrical clips, terminal connectors, stamped parts for infotainment, lighting, and control systems.
Industrial Equipment – Spring terminals, mechanical retainers, custom fasteners, and precision hardware for automation machinery.
We understand the specific requirements of each sector, including strict tolerances, high reliability, and compliance with industry standards.
Strict Quality Assurance – Consistency You Can Rely On
Quality is not just a step – it’s our culture. Our quality control system covers every production phase:
✔ Incoming material verification with certificates
✔ First‑article inspection (FAI) for every new tool
✔ In‑process sampling and SPC monitoring
✔ 100% final inspection before packing and shipment
We use precision measuring instruments such as micrometers, calipers, 2.5D optical projectors, and hardness testers. Detailed inspection reports, material certificates, and dimensional reports can be provided upon request to meet your documentation needs.
