Electrophoretic paint bracket sheet metal stamping and bending parts

The main steps of the electrophoretic paint process:

1. Surface treatment: Treat the surface of metal products, including removing impurities such as oil stains and rust, to ensure the adhesion of the paint film and the coating effect after painting.
2. Cathodic electrophoretic primer: Metal products are immersed in pre-mixed primer and used as a cathode for electrophoretic coating. In the electrophoretic coating tank, the primer particles are negatively charged and combine with the anode on the metal product to form a uniform coating, so that the surface of the metal product can achieve a certain anti-corrosion effect.
3. Drying and curing: After coating with cathodic electrophoresis primer, metal products need to be dried and cured. The curing temperature and time depend on the material and thickness of the primer. Through high-temperature curing, the primer can form a strong protective film and improve the corrosion resistance of metal products.
4. Intermediate coating: After primer treatment, metal products need to be coated with one or more intermediate coatings to enhance the adhesion and weather resistance of the paint film.
5. Top coat electrophoresis: After the intermediate coating is completed, the metal products are top coat electrophoresis coated. After topcoat electrophoretic coating, a uniform and smooth paint film will be formed on the surface of the metal product.
6. Terminal drying and curing: After the topcoat is electrophoresed, the metal products undergo terminal drying and curing.

The completion of the electrophoretic paint process not only improves the anti-corrosion performance and appearance quality of metal products, but also reduces the use of organic solvents and reduces environmental pollution. The application of electrophoretic paint plays an important role in the field of metal coating, especially in the automotive industry.

The specific electrophoretic paint process will vary depending on application occasions, product requirements, equipment conditions and other factors. In actual operation, it needs to be adjusted and optimized according to specific conditions to achieve the best painting effect.
