Electrophoretic painting technology has been widely used in industries such as automobiles, home appliances, and hardware due to its high efficiency, uniformity, and environmental friendliness. However, in the actual production process, the problem of flow marks on the surface of electrophoretic paint products sometimes occurs. This not only affects the appearance quality of the product but may also affect its protective performance and service life. So, what exactly causes flow marks in electrophoretic paint products? This article will analyze the common causes of flow marks in electrophoretic paint products and explore corresponding solutions.

　　Electrophoretic painting is a complex electrochemical process. Its principle is to immerse conductive workpieces into a water-soluble paint tank. Under the action of the electric field, the resin, pigment, and other particles in the paint… operating conditions of the equipment.

　　In summary, the occurrence of flow marks in electrophoretic paint products is a complex issue, and its causes involve multiple aspects. Only by comprehensively analyzing all factors that may cause flow marks and taking corresponding measures to control them can the generation of flow marks be effectively avoided, ensuring the quality and performance of the product. In the actual production process, it is necessary to analyze and judge according to the specific situation, find the root cause of the problem, and adopt targeted solutions to finally achieve high-quality and efficient electrophoretic painting production.
