Auto parts are exposed to outdoor environments with intense sunlight, rain, and sudden temperature changes for long periods, while also needing to maintain the consistent appearance of the entire vehicle. Metal-plastic coating, with its dual advantages of "enhancing weather resistance and aesthetics", has become an indispensable key process in automobile manufacturing, providing comprehensive protection for various parts such as interior and exterior trims, and chassis components.

In daily use and industrial production, products made of metal and plastic materials often develop surface scratches and abrasions due to collisions and friction. This not only affects the aesthetic appearance but also exposes the base material, leading to corrosion and aging, which shortens the product's service life. However, wear-resistant metal-plastic coating, with its core capability of "resisting scratches and abrasion", builds a protective barrier for products and effectively "extends their service life", making it a key process in the manufacturing of products in fields such as home appliances, automobiles, and electronics.

Dalian metal plastic coating does not contain lead, and has no pollution to the environment during the preparation, coating, and formation of the coating process. In addition, the impact on the workpiece during the construction process is relatively small, ensuring that the substrate material does not deform and its performance does not decrease. At the same time, spraying, brushing, or rolling coating processes can be used according to the different shapes and requirements of the parts to achieve coating on various friction surfaces.

Dalian metal coating process: pre-treatment - dust removal - spraying - curing (above 180 degrees).

Dalian metal plastic coating dries slowly in winter and is prone to sagging, or the primer is not dry, which affects the assembly line operation. Water based coatings, including water-based metal pigments, and aluminum silver paste itself dry slowly, making natural drying difficult in winter. How to prevent sagging and other phenomena? Actually, doing electric hot air blowing treatment and adding hot air circulation to the automatic line can effectively improve it. Coatings contain benzene derivatives such as benzene, toluene, xylene, etc.

By mixing resin and rubber, lightweight and high-strength automotive components can be produced. A research team in Japan is advancing the study of using CNF to replace iron car bodies and frames. If vehicle lightweighting can be achieved, fuel economy will be improved. The emission of carbon dioxide will also decrease. In the long run, it may even be possible to use carbon fiber to manufacture aircraft bodies.
