Core Processes and Technical Advantages  
1. Cold Extrusion Forming Technology:  
Utilizing a single-step cold extrusion forming process, the housing achieves a dense structure and high mechanical strength while minimizing material waste. Combined with Deform simulation modeling and 3D design, it enables precision manufacturing with zero draft angle, meeting stringent requirements for dimensional accuracy and assembly stability in automotive cameras.

2. Full In-House Production Process:  
From raw material processing to surface treatment, the entire production is completed within the company's own facilities. Through precise CNC clamping and integrated rear shell design (including integrated FAKRA rear shells), product consistency and reliability are ensured.

3. Surface Treatment and Reliability Testing:  
The housing undergoes ultrasonic cleaning, surface passivation, oxidation treatment, and rigorous testing such as salt spray tests, ensuring long-term stability and performance under complex operating conditions, including high temperature, humidity, and vibration.

Applications  
Smart Driving Systems: Serves as a key structural component for camera modules, suitable for ADAS, surround-view systems, in-cabin monitoring, and other automotive vision systems.  
Industrial and Aerospace Communication: Technology extended to surveillance camera housings and structural components for low-altitude economy equipment, providing high-strength, lightweight solutions.

Collaboration and Recognition  
Longto has established deep partnerships through export channels with Jaguar Land Rover (UK) and supplies precision-formed components to numerous globally renowned automotive brands and supply chains (including Sony, Panasonic, TE Connectivity, Rosenberger, Toyota, Volkswagen, BMW, Tesla, Huawei, etc.). Based on three years of R&D and nearly 100 optimized solutions, the company has become a leading enterprise in the domestic cold-extruded camera housing sector, with an annual planned capacity of 30 million units, committed to setting industry process standards.

Core Value  
High Precision and Reliability: Meets stringent requirements for tolerances, strength, and environmental endurance in automotive smart driving core components.  
Lightweight and Cost Optimization: Aluminum alloy cold extrusion ensures performance while reducing weight and minimizing subsequent processing costs through near-net shaping.  
Full-Process Quality Control: From simulation design to surface treatment, the entire process is controllable and traceable, ensuring stable quality in mass production.
