The automatic spraying line can complete the entire coating process including primer, intermediate paint, topcoat and UV paint on one single production line. 

The following is an example of a Chinese introduction to the automatic spraying line:

The automatic spraying line is an efficient and integrated coating production system. On this production line, all the coating processes of primer, intermediate paint, topcoat and UV paint can be completed in sequence.

The primer, as the base coating, can provide a good adhesion foundation for the subsequent coating and effectively enhance the bonding strength between the entire coating and the surface of the object to be coated. The intermediate paint plays a role in further filling, leveling and enhancing the overall thickness and stability of the coating, making the paint surface effect more uniform and smooth. The topcoat is the key coating that ultimately presents the appearance effect. It determines the color, glossiness and overall aesthetic degree of the surface of the object to be coated. And the UV paint, relying on its unique curing characteristics, can quickly dry and solidify after being irradiated by ultraviolet rays, forming a high-quality paint surface with high hardness, good wear resistance and chemical corrosion resistance, which greatly improves the quality and durability of the surface of the object to be coated.

By integrating the coating of these several kinds of paints on one production line, it not only effectively improves the coating efficiency and reduces the turnover time and manpower and material costs among different processes, but also can better ensure the connection quality among various coatings, ensuring the consistency and high quality of the final coating effect. It is widely applicable to the production fields of various products with relatively high requirements for appearance and surface quality, such as furniture, auto parts, electronic product casings and so on.
