Parts of different sizes have different requirements and applicability in the coating process. The following are several common coating processes:
The first is spraying. Spraying is a common coating process that is suitable for parts of various sizes. It is used to spray paint evenly on the surface of the part. This method can quickly coat large areas of parts, but smaller sized parts may require finer control. For example, waterborne anti-corrosive acrylic primer and pipeline anti rust paint. These paints can be used by spraying.
The second is roll coating. It is a coating method suitable for small size parts. This method uses a roller to roll the paint onto the surface of the part, resulting in a relatively uniform coating. Roller coating is generally suitable for flat or large bending radius parts. Some paints can be used by roll coating such as waterborne polyurethane varnish for vessels and port machinery polyurethane coatings.
The third is dip coating. Dip coating is a coating method suitable for small parts. The parts are dipped in paint, then removed and dried under appropriate conditions. This method is suitable for parts with complex shapes that cannot be coated by other methods.
The fourth is electrophoretic coating. Electrophoretic coating is a coating method suitable for parts of various sizes. The parts are dipped in electrophoretic paint, then arranged on a conductive mesh by an electric field, and finally the curing and drying process is carried out. Electrophoretic coating can achieve uniform coating, with good durability and corrosion resistance.
The fifth is powder coating. Powder coating is suitable for parts of all sizes, including small and medium-sized parts. This painting method uses static electricity to attach the powder coating to the surface of the part, which is then subjected to a drying and curing process. Powder coatings have a strong light finish and can achieve a variety of colors and effects.
We can choose the appropriate coating process according to the actual needs to ensure that the parts get the best coating effect and quality.
