Eisenmann
Pretreatment as a Prerequisite for First-Grade Coating
Depending on the size of the workpiece and the requirements of the customer, Eisenmann provides tailor-made pretreatment plants for painting.
Spray Pretreatment Plants
Eisenmann designs customized spray pretreatment plants which comprise cleaning stages (degreasing), rinsing stages and film-forming procedures such as zinc phosphating and nano-layer deposition.
Dip Pretreatment Plants
Dip pretreatment plants are mainly made up of multiple dip basins. Hoists cycle the metal workpieces through the various bath media. This systems engineering technology is especially qualified for pretreating workpieces with complex geometries.
Pretreatment Procedures
In the pretreatment plant, the workpiece is pretreated in multiple process steps.
Primarily these are:
- Degreasing / cleaning
- Pickling
- Activating
- Phosphating
- Conversion-layer deposition
