Dip (Immersion) Pretreatment Line

A dip (immersion) pretreatment line is a system in which parts are treated by immersing them in liquid chemical baths for the purpose of cleaning, degreasing, phosphating, or applying other chemical processes to metal surfaces prior to painting or coating. It ensures that the chemical contacts every point of the surface uniformly, especially on parts with complex geometries.

Features

• Bath tanks are generally manufactured from stainless steel or special chemical-resistant materials.

• Sequential processes can be applied with a multi-stage system (degreasing, rinsing, phosphating, passivation, etc.).

• Chemical temperatures are kept under control thanks to heating systems.

• Chemical homogeneity is ensured with mixing and circulation systems.

• The entry and exit of parts into the baths can be performed automatically with conveyor or hoist transport systems.

• Small or large parts can be processed thanks to tanks of different sizes.

• Long-term and efficient use with filtration and automatic chemical dosing systems.

• Environmentally friendly design with closed-circuit water and chemical use.

Functions

• Removes oil, dirt, rust, and oxide layers from the surface of parts.

• Applies phosphating and passivation processes that enable the paint or coating to adhere better to the surface.

• Provides homogeneous surface preparation at every point of parts with difficult geometries.

• Offers fast and reliable surface treatment capability in mass production. • Increases the corrosion resistance of parts before coating.

• Reduces costs by optimizing chemical usage.

• Reduces waste generation with its environmentally conscious design.
