A complete coating inspection consists of three parts: performance testing of the coating itself, quality control of the coating process, and evaluation of coating performance after coating. Here are some key points of coating inspection.

The resistance to abrasion is a measure of the difficulty of obtaining a smooth and matte surface during the coating process of coating products by grinding materials such as sandpaper or pumice on the paint film or putty layer.

An automatic spray coating machine applies coatings by atomizing the paint and spraying it onto the workpiece (substrate). The flow pressure is generally set between 0.1 to 0.6 Mpa.
