Core Technology & Advantages

Cold Extrusion Forming Technology
Single extrusion forming enables efficient structural shaping without draft angles, significantly improving material utilization and dimensional consistency.
Combined with metal plastic forming and DEFORM simulation, the forming process is optimized to ensure defect-free interiors and uniform wall thickness.

High-Precision Manufacturing System
Utilizes CNC precision clamping and full-process control to achieve micron-level accuracy in critical apertures and mounting surfaces.
Supports integrated rear shell design (with optional FAKRA connector integration), reducing assembly steps while enhancing sealing and anti-interference performance.

Full In-House Process Coverage
Complete internal production from 3D modeling and design, cold extrusion, precision machining, to surface treatment.
Surface treatment includes ultrasonic cleaning, passivation, and anodization processes, with salt spray tests conducted to verify corrosion resistance for demanding automotive environments.

Material & Lightweight Advantages
Made from high-strength aluminum alloy, offering structural robustness while achieving lightweight design goals—ideal for new energy vehicles and smart driving components.

Applications
Vehicle camera front/rear housings
Lidar housings
Sensor protective housings
Core components for smart driving vision systems
