Powder coating is a commonly used technique in sheet metal processing, enhancing the workpiece's surface with a beautiful and elegant appearance while providing corrosion resistance. The raw material used in powder coating, which is essentially a thermosetting powder coating, has gained popularity as a high-performance, low-hazard, low-pollution, energy-saving, and environmentally friendly coating. It has become one of the main products replacing traditional solvent-based coatings.

Advantages of spray painting as the surface treatment for sheet metal processing workpieces:

The painting process saves production steps, reducing the production cycle, typically requiring only one coating application, with a thickness ranging from 30 to 500 micrometers.

2. Compared to paints used for spray painting, plastic powder is non-flammable and non-explosive, and it does not contain volatile substances, thus no ventilation and cooling equipment is required.

3. Powder coatings have a good edge adhesion rate and do not exhibit sagging or露底 issues.

4. The cured coating of thermosetting powder coatings exhibits high tensile strength, significantly reducing the potential for damage during transportation and assembly of coated parts. The film coating can also be subjected to mechanical processing and manufacturing.

5. The application of automatic spraying equipment on the production line enables automatic adjustment of the coating film.
