Electrophoresis, commonly known as E-coating, is a finishing process where a part is immersed in a water-based paint solution and an electric current is applied. The paint particles migrate and deposit onto the part, forming a highly uniform and complete coating, even in recessed areas and complex geometries. Cathodic electrophoresis, the most common type, provides excellent corrosion resistance and is widely used as a primer in the automotive industry. An automated E-coating line from Raymond provides precise control over voltage, immersion time, and curing temperature, resulting in a consistent, high-quality finish that serves as a perfect base for subsequent topcoats.
