The performance and quality of the automobile chassis depends to a large extent on its sheet metal processing technology. We focus on automotive chassis sheet metal processing, with superb technology and advanced equipment, for customers to create high-quality chassis sheet metal parts.

Fine cutting, precise size
In the initial stage of automobile chassis sheet metal processing, the blanking process is very critical. We use high-precision CNC shearing machine, according to the chassis design drawings, all kinds of sheet metal plate precision cutting. Whether it is a conventional shape or a complex profiled profile, the CNC shearing machine can complete the cutting with extremely high precision, and the error is controlled within a very small range. This not only ensures the accuracy of the sheet size, but also provides a good basis for subsequent processing to avoid assembly problems caused by blanking deviations.

Multi-component molding to shape the chassis structure
The forming process is one of the core parts of the automobile chassis sheet metal processing. For different parts of the chassis, we use a variety of forming methods. For the frame structure of the chassis, a large CNC bending machine is used. By precisely setting parameters such as bending Angle and radius, the sheet metal sheet is bent into the desired shape to ensure the strength and structural stability of the frame. For some parts with complex curved surfaces, such as the sheet metal shell of some suspension parts, the hydraulic forming process is used. Under the action of high-pressure liquid, the plate can be uniformly fitted to the mold, accurately shaping the complex curved shape, to meet the strict requirements of the automobile chassis for the shape and performance of the parts.

High quality welding, stable connection
Welding is an important means to realize the connection of chassis sheet metal parts. We use advanced gas shielded welding technologies such as carbon dioxide shielded welding and argon arc welding. When welding key components such as chassis girders, carbon dioxide shielded welding, with its efficient and stable welding characteristics, can quickly form a strong weld, improve production efficiency and ensure welding quality. For some parts with high welding quality requirements and strict appearance smoothness requirements, such as the welding of some chassis decorative parts, argon arc welding is selected. Argon arc welding can accurately control the welding heat, reduce the heat affected zone, make the weld beautiful and high strength, ensure that the chassis components are firmly connected, and the overall structure is safe and reliable.

Fine surface treatment, improve protection and beauty
After the completion of welding, the car chassis sheet metal parts for a comprehensive surface treatment. Foremost, the grinding process is carried out, and the burrs and welding slag left by welding are removed through the combination of mechanical grinding and manual fine grinding, so that the surface of the sheet metal is smooth and smooth. Then paint treatment, the selection of high-quality automotive special paint, the use of electrostatic spraying process. Electrostatic spraying can make the paint evenly attached to the surface of the sheet metal, forming a layer of uniform thickness, strong adhesion of the paint film, effectively improve the chassis rust, corrosion resistance, but also for the car chassis to add beauty, extend its service life.

Our automotive chassis sheet metal processing, from fine to perfect surface treatment, every process is excellence, committed to providing customers with high quality, excellent performance of automotive chassis sheet metal products, help the automotive industry to create more high-quality, reliable automotive chassis.
