We have supplied Car Production Line for more than 32 years.
The Car Production Line is the entire process of manufacturing a car, which includes several key processes: stamping, welding, painting, and assembly. Below, I will detail these processes:
1. **Stamping Process**: This is the first step in car manufacturing, where sheet metal is pressed into the vehicle's exterior using a stamping press. It is estimated that 60% to 70% of a car's parts are produced through stamping processes. Stamping processes are divided into forming operations and separation operations, including basic operations such as blanking, bending, drawing, and local forming.
2. **Welding Process**: The stamped parts are sent to the welding shop, where they are assembled into a complete body-in-white by welding robots and automated equipment. The welding process is one of the essential engineering steps in整车 manufacturing, mainly consisting of a large number of welding robots and computer-controlled automated welding equipment.
3. **Painting Process**: The welded body-in-white enters the painting shop for rust prevention treatment and painting. The painting process includes pre-treatment (such as phosphating or e-coat rust prevention treatment), electrophoretic coating, primer, color coat, and clear coat, to protect the body and provide an aesthetically pleasing appearance.
4. **Assembly Process**: The purpose of the assembly process is to combine the body, chassis, and interior parts into a complete vehicle. In the assembly shop, doors and other components are disassembled for other processes and then reassembled to complete the interior, chassis, and other accessory assemblies, and finally, the final quality and performance inspection is completed before leaving the factory.
5. **Inspection Process**: Finally, the car goes through a series of inspection processes to detect potential quality issues in the production and assembly process, ensuring that non-compliant products do not leave the factory. This includes inspecting the components in the engine compartment, adding necessary fluids, conducting four-wheel alignment tests, and sealing performance tests, etc.
Modern automobile production lines have improved production efficiency and product quality, reduced waste and inventory, and achieved more efficient and intelligent production by applying advanced automation technology and intelligent manufacturing systems.
