The most widely used coating process in China is the paint coating process. The coating process can ensure the appearance quality of Changzhou paint buckets and enhance the anti-corrosion ability of paint buckets. The coating process can be divided into air spraying, electrostatic spraying and high pressure airless spraying according to the spraying method.
Before painting, we must first carry out processes such as degreasing, rust removal, phosphating, cleaning and drying on the paint bucket to ensure the quality of the painting and improve the adhesion of the paint film. For paint bucket products with low appearance requirements, the method of manually wiping the bucket can also be used, which can effectively reduce the cost. The final process of painting is the printing of the logo. In the early years, the logo of Changzhou paint bucket was air spraying, and the hollowed logo plate was used to spray characters. With the progress of users' requirements for the surface quality of Changzhou paint buckets, now logo printing has been gradually replaced by better screen printing and thermal transfer technology.
