SUV/Sedan Assembly Line

Sedan/SUV assembly lines are production lines in car manufacturing plants used to assemble cars. They are a key part of mass production, assembling various parts and components into complete cars according to a specific sequence and process.

Here is a general introduction to sedan/SUV assembly lines:

Stamping Shop: Production begins in the stamping shop, where large stamping machines process metal sheets into car body panels and other structural parts.

Welding Shop: The stamped parts are sent to the welding shop, where automated welding robots assemble them into the car body frame.

Painting Shop: The welded car body frame enters the painting shop for cleaning, phosphating, electrophoretic primer coating, and application of color and clear coats.

Final Assembly Shop: The painted car body is sent to the final assembly shop for the final assembly of the car, including the installation of the engine, transmission, suspension, braking system, interior, electrical system, wheels, and tires.

Interior Assembly: Seats, dashboards, steering wheels, control panels, carpets, and other interior decorations are installed on the assembly line.

Electrical System Assembly: Electrical components such as batteries, starter motors, lighting systems, sensors, and infotainment systems are installed.

Engine and Transmission Installation: Engines and transmissions are installed onto the car body and connected to the corresponding pipelines and electrical systems.

Wheel and Tire Assembly: Wheels and tires are installed and balanced and aligned.

Final Inspection and Testing: Completed cars undergo a series of inspections and tests, including wheel alignment, brake testing, light checks, and engine performance testing.

Quality Control: Rigorous quality control is conducted to ensure that each car meets production and safety standards.

Pre-delivery Preparation: Cars that pass inspection are cleaned, refueled, and finally adjusted, and necessary labels are applied.

Logistics and Delivery: Finally, cars are sent to dealers through the logistics system or delivered directly to customers.

With technological advancements, modern sedan/SUV assembly lines widely adopt automation, robotics, and information management systems to improve production efficiency, reduce costs, enhance product quality, and achieve more flexible production capabilities to adapt to market changes. At the same time, environmentally friendly and energy-saving design philosophies are also integrated into various stages of the assembly line.
