The E-Coating process is a mixture of the Plating process and Painting, where a DC voltage is passed through the workpiece while immersed in a water-based solution with a paint emulsion. The process results in the paint to adhere to the surface of the piece and form a layer. Moreover, to create attractive designs, E-Coating processes are used to get Corrosion protection a smooth and Lasting Finish. A Source of DC Voltage is a primary requirement for the E-Coating process.
