Coil Coating

Litho Strip Cleaning

Layout of the aluminum strip pretreatment plant

Coated aluminum strips – manufactured by means of the coil coating procedure – are gaining more and more in importance in industrial manufacturing processes. Especially their use in the food, building and automotive sectors is achieving high growth rates. For this purpose, an effective pretreatment is indispensable for optimum coating with high quality standards.

Within coating plants for aluminum strips, Eisenmann supplies appropriate pretreatment plants. This process is decisive for the subsequent coating of aluminium strips. To achieve an optimum surface, the effective removal of surface contaminants is not enough. In addition, the existing oxide layer on the surface of the strip must be removed by pickling and a conversion layer needs to be applied.

Eisenmann even has a solution for this requirement and supplies high-quality systems to ensure the process parameters in narrow confines. To reduce the energy and media consumption to a minimum, our engineers rely on a combination of sophisticated system technology and intelligent control engineering. To learn more about this topic, please refer to the data sheet aluminum strip pretreatment for coating lines.

Pretreatment plants for aluminum strips coating lines typically include the following process steps:

  • Alkaline degreasing
  • Rinsing
  • Pickling
  • Rinsing
  • Conversion treatment
  • Blow-off zone for drying and cooling

Eisenmann can also resort to varied experience in the field of pretreatment of steel strips for coating lines. Our specialists will be glad to provide you with more information on request.
