As a key part of the appearance and structure of the automobile, the production process of the automobile skin sheet metal is directly related to the overall quality of the vehicle. We create automotive skin sheet metal parts with exquisite technology to provide quality products for the automotive industry.

Strict selection of suitable materials to ensure the foundation of performance
In the selection of materials, we use diversified materials according to the different needs of automotive skin sheet metal parts. For the parts that bear greater external forces, such as the door frame, the selection of high-strength alloy steel, which has excellent impact resistance, can effectively ensure the safety of the vehicle in the collision. For lightweight and beautiful roof skin, we use lightweight and excellent surface quality aluminum alloy sheet, not only reduce the weight of the body, but also improve the appearance of the texture. Each batch of material is rigorously tested for physical and chemical properties, from hardness and tensile strength to corrosion resistance, ensuring full compliance with the high standards of automotive manufacturing.

Multiple methods combined with cutting, precise size cutting
Cutting link, we use a variety of advanced technology. For plates with regular shape and large size, such as the cutting of the side skin of the body, the CNC shearing machine is used for efficient cutting, and the initial outline can be cut quickly and accurately. For complex shapes and parts requiring high precision, such as the shaped edges of the hood, we use water knife cutting technology. The water knife mixes abrasives with high pressure water flow, and can cut extremely fine shapes without thermal deformation. The incision is smooth and smooth, and the accuracy is extremely high, providing accurate billets for subsequent processing and minimizing material waste.

Composite molding process to create a smooth shape
Molding is the key to shaping the unique appearance of automotive skin sheet metal parts. For the plane part, the use of CNC stamping combined with die forming, through the precise control of the stamping pressure and stroke, the plate can be quickly stamped into the required plane shape, to ensure the flatness and dimensional accuracy. For the curved parts of the body, such as the arc modeling of the door, the rolling molding process is adopted. Under the continuous pressure of the roller, the sheet is gradually bent into a specific surface, which ensures a natural and smooth transition of the surface, perfectly fitting the streamlined design of the car and optimizing the aerodynamic performance of the vehicle.

Multiple welding technology, stable overall structure
Welding is an important process for connecting automotive skin sheet metal parts. For the non-visible parts of the body, we use numerous gas shielded welding, its welding speed, deep penetration, to ensure the strength of the connection, while effectively controlling welding deformation. In the visible parts of the body surface, such as the body joint, laser brazing technology is used. Laser brazing uses laser as a heat source to melt the filler metal and fill the weld, the formed weld is beautiful and has high strength, and is almost integrated with the base material, which not only improves the appearance quality of the body, but also enhances the stability of the overall structure.

Comprehensive surface treatment for enhanced protection and appearance
The surface treatment gives the dual characteristics of protection and aesthetics to the automotive skin sheet metal parts. First, phosphatizing is performed to form a phosphate protective film on the surface of the sheet metal to enhance the adhesion of the subsequent coating. Then electrostatic powder spraying, using the principle of electrostatic adsorption, so that the powder coating evenly attached to the surface of the sheet metal, and then after high temperature curing, forming a hard, wear-resistant and durable color coating. Finally, the skin sheet metal parts of some high-end models will also be polished to further enhance the surface gloss and make the appearance of the car more beautiful.

Through strict control of each production process, we are committed to providing customers with high-quality and high-performance automotive skin sheet metal parts, helping automobile manufacturers to create more competitive automotive products.
