Advanced E-Coating Solution for Battery Housing Protection

This customized electrophoretic coating production line is specifically engineered for automotive battery enclosures, battery trays, and other metal housing components requiring excellent corrosion protection and long-term durability.

Using advanced cathodic electrophoretic deposition (CED/KTL/EPD) technology, the system applies a uniform protective coating layer to the entire surface of immersed components. Even complex structures, internal cavities, and recessed areas can achieve consistent coating coverage, improving product reliability and service life under demanding automotive conditions.

Technical Overview of Electrophoretic Coating (E-Coating)

Electrophoretic coating is also known as:

• Electrophoretic Deposition (EPD)

• Electrocoating

• Cathodic Electrodeposition (CED)

• KTL Coating

The process uses a water-based coating system combined with electrical current to deposit paint particles onto conductive metal components.

During the process:

1. Metal parts are immersed in the electrophoretic paint bath.

2. Electrical voltage causes charged paint particles to migrate toward the workpiece.

3. A uniform coating film forms on the metal surface.

4. The coated parts are cured in an oven to achieve final coating performance.
