Workpieces, which have surfaces that are difficult to access, are advantageously treated in immersion cleaning systems. They ensure that not only the external surfaces are treated but also all cavities. This type of pretreatment is particularly recommended for complex geometries where a spray system cannot reach the entire surface.
AFOTEK plans and projects the entire system based on customer-specific products and requirements and develops the optimum concept in cooperation with chemical suppliers concerning the number and length of the process steps.
The various immersion basins are usually arranged in rows or in a horseshoe-shape. The size of the immersion pretreatment depends both on the size of the workpieces and on the required treatment steps. An integrated conveyor system completes the automated process of the AFOTEK immersion pretreatment.
Compared to conventional spray pretreatment systems, immersion pretreatment is characterized by lower energy consumption as well as high-quality corrosion protection of steel and aluminum components.
