Description

Our OEM automotive relay manufacturing solution is designed to meet the demanding requirements of modern vehicle electrical systems. Backed by advanced CNC machining capabilities, we deliver high-precision relay components that ensure stable conductivity, durability, and long-term performance.

We utilize high-conductivity materials such as stainless steel (SUS304/316L) and copper alloys like phosphor bronze, combined with nickel or tin plating to enhance electrical performance and corrosion resistance. Each component is engineered with a cylindrical structure, featuring precision-machined internal bores or threaded interfaces to ensure seamless integration into relay assemblies.

With a flexible size range (Φ8mm–Φ25mm diameter and 10mm–40mm height), we support full customization based on your design requirements. Our manufacturing process integrates CNC turning, precision grinding, and electrochemical polishing, resulting in smooth surfaces, tight tolerances, and superior finishing quality.

As a trusted CNC machining partner, we focus on delivering reliable OEM automotive relay components that meet strict automotive standards, helping brands improve product performance and maintain consistency in high-volume production.
