Het meest gebruikte coatingproces in China is het verfcoatingproces. Het coatingproces kan de uiterlijke kwaliteit van de verfemmers van Changzhou garanderen en het anti--corrosievermogen van verfemmers verbeteren. Het coatingproces kan worden onderverdeeld in luchtspuiten, elektrostatisch spuiten en hogedruk airless spuiten volgens de spuitmethode.
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.
