Core Technical Advantage: Cold Extrusion Process
1.  Outstanding Mechanical Properties: Our Cold Extrusion Process forms the part under immense triaxial compressive stress. This significantly increases the material's strength and hardness, optimizes metal grain flow, and thereby enhances the component's fatigue resistance, impact toughness, and overall structural integrity, meeting the stringent demands of vehicles under all-weather and all-road conditions.

2.  High Precision and Consistency: Guided by mold design and process optimization informed by Deform Simulation Modeling, combined with subsequent machining featuring Precise CNC Fixturing, we achieve high dimensional accuracy through Single Extrusion Forming. Under stable process conditions, the product exhibits Exceptional Product Consistency, ensuring perfect compatibility for the automated assembly of high-end image sensors from Sony and Panasonic, as well as connectors from TE Connectivity and Rosenberger.

3.  "Near-Net-Shape" Forming and Structural Innovation: This process offers High Material Utilization and is an efficient "near-net-shape" technology. We can achieve complex geometric shapes Without Draft Angles on the housing, and can produce Integrated Rear Housings and Integrated FAKRA Rear Housings, reducing part count and improving overall reliability.

Full-Process Quality Assurance

We adhere to conducting the Entire Production Process In-House, ensuring full control from raw material to finished product:

Surface Treatment and Corrosion Resistance: Products undergo Ultrasonic Surface Cleaning to ensure complete Degreasing and Oil Removal, eliminating issues like dark spots or blackening that could affect optical accuracy. Subsequent Surface Passivation or Surface Oxidation treatments enable the product to easily pass stringent testing requirements, including Salt Spray Testing for over 96 hours, meeting the long-term corrosion resistance needs of the automotive environment.
Density Assurance: The immense pressure during cold extrusion results in a Dense Microstructure, closing micro-defects in the raw material. This not only increases strength but also enhances the component's air tightness, providing optimal protection for the internal precision electronics.
