Pretreatment dipping process.

We design specifically for each customers production line.

We do not use off-the-shelf systems. Instead, we engineer solutions tailored to the actual production processes of each factory from facility size and workflow direction to seamless integration with conveyor systems and curing ovens.

The result is a system that delivers maximum efficiency, optimized space utilization, and real increases in production capacity.

Pretreatment Dipping Process

Pretreatment Dipping Process is a surface preparation method performed prior to painting, in which workpieces are immersed sequentially in chemical tanks. Typical steps include degreasing, derusting, rinsing, and phosphating to ensure the metal surface is clean and properly prepared for coating.

This process improves paint adhesion, enhances corrosion resistance, and extends the service life of the workpieces.



This system is ideal for workpieces with complex shapes or hard-to-reach areas where spray nozzles cannot effectively access, such as automotive components, steel structures, machinery, and industrial equipment.

It is commonly integrated with an overhead conveyor with jig system, which automatically lowers and lifts workpieces into and out of each tank. This ensures high cleaning efficiency, consistent results, and easy quality control throughout the process.
