Automotive coating process introduction

The automotive painting process can generally be divided into two parts: one is the surface treatment of the metal before painting, also called pre-treatment technology; the second is the coating construction process. The surface treatment mainly includes removing oil stains, dust, rust on the surface of the workpiece, and removing the old paint layer during the repair work to improve the surface state of the workpiece. This includes machining and chemical treatment of the workpiece surface according to various specific conditions, such as phosphating, oxidation and passivation.
