Technical Advantages  
1. Advanced Forming Process  
Utilizes single-step cold forging to achieve an integrated housing structure, free of welds and draft angles, ensuring dimensional accuracy and structural strength.  
Integrates metal plastic forming theory with simulation analysis to optimize metal flow channels, extending mold life, and ensuring product consistency.  

2. End-to-End In-House Control  
The entire process—from billet design, cold extrusion, CNC precision machining, to surface treatment (ultrasonic cleaning, passivation, salt spray testing, oxidation protection)—is completed in-house, ensuring quality and delivery reliability.  

3. High Precision and Reliability  
Strict control over product tolerances meets the demanding requirements for dimensional stability and environmental durability in vehicle camera applications.  
Passes salt spray tests and multiple reliability validations, ensuring performance in complex automotive environments.  

Applications  
Core Components for Smart Driving: Used in front-view, surround-view, and in-cabin monitoring camera modules.  
Customer Coverage: The product has been integrated into international supply chains including Sony, Panasonic, TE Connectivity, Rosenberger, and supports brands such as Toyota, Volkswagen, BMW, Audi, Tesla, Li Auto, Huawei, Xiaomi, and others.  

Core Value  
Technology Leadership: As the initiator of cold extrusion camera housing standards, the company relies on processes certified by the China Forging & Stamping Association and holds Chinese patents for cold extrusion vehicle camera housing technology.
