Immersion systems typically require only placing the workpiece into the treatment tank and controlling key parameters.
The operation is straightforward and highly compatible with automated control, reducing manual intervention, improving consistency, and boosting production efficiency.
With proper process design, immersion pre-treatment enables high recycling rates of treatment solutions, reducing chemical consumption and wastewater discharge.
Its superior treatment performance also minimizes coating defects caused by inadequate pre-treatment, indirectly reducing energy and material waste.
Dip Tank Pretreatment, also known as immersion pre-treatment, the workpiece is completely submerged in the treatment solution, where chemical reactions or physical actions between the solution and the surface achieve degreasing, derusting, phosphating, and other processes. This method is suitable for workpieces with regular shapes and smooth surfaces, delivering highly uniform treatment results. However, it requires a relatively large equipment footprint and higher consumption of treatment chemicals.
ShengTai Painting Equipment designs robust immersion systems for Electrophoresis coating, ensuring stable operation, precise process control, and consistent surface quality.

Advantages of Dip Tank Pre-treatment
1. Thorough treatment
Immersion pre-treatment allows the workpiece to be fully exposed to the treatment solution, ensuring that all internal and external surfaces—including cavities, gaps, and corners—are completely processed. Oil, rust, and impurities are effectively removed, making it especially suitable for complex structures and eliminating blind spots. This creates an ideal foundation for high-quality Electrophoresis coating.
2. Excellent uniformity
Because the workpiece is evenly soaked in the solution, contact conditions remain consistent across all surfaces. This guarantees uniform pre-treatment results, providing a stable and even substrate for subsequent coating stages and significantly improving coating uniformity and adhesion in the E coating line.
3. Reduced secondary contamination
Compared with spray pre-treatment, immersion pre-treatment minimizes the risk of contaminants reattaching to the surface due to spray pressure or airflow. Pollutants are fully dissolved or chemically removed, reducing secondary contamination and enhancing final coating quality.
4. Strong adaptability
Process parameters such as solution composition, concentration, temperature, and treatment time can be flexibly adjusted to suit different materials, contamination types, and production requirements. Immersion pre-treatment is suitable for various metals, including steel and aluminum alloys, meeting diverse Electrophoresis coating process demands.
