Manufacturing Technique

STAMPING

We utilize a large-scale automated enclosed stamping line. The entire line features robotic automation for loading and unloading, along with waste collection and conveying systems, and a rapid die change system to ensure efficient and safe production with stable quality.

We employ 3D/2D visual recognition systems and automatic alignment for robotic material handling.

For chassis stamping, we use a 6300-ton mechanical straight-side press and a 5000-ton hydraulic press manufactured by SMG in Germany, equipped with fully automated loading and unloading systems, ensuring high production efficiency and stable forming quality. Automated guide pin control of forming dies ensures high forming accuracy and short changeover time.

WELDING

In our production process, we utilize flexible equipment systems such as tetrahedral, cross slide, and NC fixtures to adapt to mixed-model production, enabling seamless model switching without stopping the line. We employ robotic automatic welding and laser fiber welding processes, ensuring high automation, stable quality, and high efficiency.

The entire line employs automated mechanical conveying, with the main line using high-speed roller beds and flexible trolleys, and robots for large part handling, and AGVs for material distribution.

We have set up online inspection workstations to monitor body accuracy and quality in real-time. Ultrasonic testing is used to ensure weld quality. We use Faro coordinate measuring machines or blue light scanning to ensure assembly quality.

Our welding assembly is a smart, digitized factory, utilizing technologies such as digital twins, offline programming, and virtual debugging to simulate, evaluate, and optimize the entire production process.

We employ multiple sets of intelligent systems such as MES, central control management, and video surveillance to ensure smooth and efficient production throughout the entire body shop process.

COATING

Equipment Advancement: For pre-treatment electrophoresis, we utilize a U-shaped double-pendulum continuous conveyor, and for spraying, we employ a wall-mounted high-flow robot system with fully automated conveying and automatic recognition and tracking systems for carrier bodies, achieving flexible and efficient production.

Technological Material Advancement: We employ a compact water-based 3C1B process for painting, with electrophoresis using high-penetration, high-appearance, lead-free electrophoretic paint. Intermediate coating and color paint use water-based coatings, while clear paint employs high-solid content coatings.

Environmental Protection and Energy Conservation Advancement: Our drying ovens utilize a recycled heat incineration system, achieving a 99% efficiency in exhaust gas treatment with heat recovery. The paint booths utilize recycled air technology, realizing green production.

FINAL ASSEMBLY

Final assembly utilizes friction lines and other automated intelligent conveyance systems with low energy consumption and low noise for the entire vehicle production.

Internal logistics employ the SPS distribution method, ensuring 100% sorting and error-prevention indications, with AGVs for automatic transportation. Major assemblies such as tires, seats, and engines are transported automatically in the air.

We implement an informationized pedigree management system, ensuring 100% traceability in quality control. Production status is monitored visually.

We establish torque recording and tightening error prevention systems to prevent incorrect tightening or missed tightening of critical components during operations. This system also stores, statistically analyzes, and traces torque data.
