High-Precision Corrosion-Resistant Metal Terminal Housing with Custom Size for Automotive Connectors

High-Precision Metal Terminal Housing | Corrosion-Resistant | Custom Size & Plating | For Automotive Connectors

Product Description:

Our Metal Terminal Housings are engineered to provide reliable protection, precise alignment, and stable connection for a wide range of electrical terminals and connector assemblies. Designed with meticulous attention to detail, these housings are manufactured through high-precision stamping and forming processes, ensuring consistent dimensions, smooth edges, and a flawless fit during assembly. The result is a product that delivers exceptional mechanical stability, excellent electrical conductivity, and long-term reliability even under harsh environmental conditions.

Each housing is produced from premium-grade metals such as brass, phosphor bronze, stainless steel, or copper, chosen for their outstanding strength, conductivity, and resistance to corrosion. Depending on application needs, the surfaces can undergo tin, nickel, or zinc plating, effectively enhancing wear resistance, oxidation protection, and solderability — ideal for high-performance electrical systems.

Our production process follows strict quality control standards at every stage, from material selection and tooling design to final inspection. With tight dimensional tolerance up to ±0.01 mm, our terminal housings maintain perfect consistency and compatibility with various connector systems.

The design is fully customizable — including dimensions, shape, plating type, and packaging — to meet specific technical and aesthetic requirements. Whether you need a lightweight housing for consumer electronics or a heavy-duty design for automotive or industrial use, we can tailor solutions to your exact specifications.

We also offer comprehensive OEM and ODM services, supporting customers with prototype development, tool design, and mass production. Our engineering team works closely with clients to ensure that every product not only meets functional expectations but also optimizes performance and cost efficiency.
