Efficiency doubled, cost dropped sharply - automatic spraying machine, a must-have for enterprise upgrade

Regarding plastic box spraying, here are a few key points to note:

1. **Surface cleaning**: Before spraying, the plastic surface needs to be thoroughly cleaned to ensure the adhesion of the paint. This is a key step to ensure that the paint is firmly sprayed.

2. **Adhesion promoter**: If the paint peeling problem occurs after spraying, an adhesion promoter can be used to improve the adhesion and solve the paint peeling problem.

3. **Treatment agent**: The use of a treatment agent can improve the interlayer adhesion between the substrate and the paint coating. This method is not only suitable for spraying on plastic surfaces, but can also be widely used in spraying on metal surfaces.

4. **Plastic spraying technology**: Plastic spraying is a technology that uses corrosion-resistant materials to isolate corrosive media from substrate equipment, and has a variety of characteristics and applications.

5. **Process flow**: The process flow of plastic product spraying includes steps such as purification and roughening of the surface to be sprayed, surface preheating, spraying and cleaning.
