Core Technology and Advantages

Single-Stage Cold Extrusion Forming
Utilizes one-step extrusion forming to ensure a compact housing structure with no draft angle, improving space utilization and assembly accuracy.
Employs 3D modeling design and Deform simulation-based forming to optimize blank and mold design, ensuring high dimensional stability and material utilization.

End-to-End In-House Production and Quality Control
The entire production process—from raw material to finished product—is completed in-house, including CNC precision machining, ultrasonic surface cleaning, passivation treatment, and oxidation treatment.
Rigorous testing, such as a salt spray test, ensures compliance with automotive-grade standards for corrosion resistance, sealing, and laser welding reliability.

Lightweight and Thermal Management Design
The aluminum alloy material and integrated structure achieve lightweight performance while providing excellent heat dissipation, ensuring long-term operational stability of the camera.

Application Scenarios
Front/Rear/Surround-View Vehicle Cameras
Sensor Protection Housings
Core Smart Driving Perception Components (e.g., camera front shells, rear shells, and integrated FAKRA rear shells)
