Zinc flake coatings are clearcoatings consisting of zink and aluminium flakes, its great advantage is that a high corrosion resistance will be provided for the coated metal parts, even by a low layer thickness (8-30 µm). In the dip spinning processs such coating material will be applied to the surface of the prepared mass products and – due to the low baking temperatures – this process is also suitable for surface treatment of heat-treated parts and high-strength fasteners without hydrogen embrittlement. This coating system provides a cathodic protection for the coated parts and in this protection the zinc and aluminium flakes appear as about victims in the corrosion process, activating and protecting the base metal against formation of red rust in this way.

By using the dip spinning process we offer Dörken Delta MKS (Delta-Protekt, Delta-Tone, Delta-Seal) and MAGNI (Magni 565, Magni 560, Magni 595) coatings, typical areas of application are connecting elements for brakes and seat belts, springs, fasteners, lock parts used in the automotive industry.

Cathodic dip coating is one of the most common systems used for corrosion protection. Since 2008 we offer it to parts made of steel, aluminium and galvanized sheet. In addition to normal layer thickness (10-25µm) ,our equipment is also suitable for surface treatments with higher layer thickness (40-60 µm). The method and thus the coating system complies with the most common standards of the machine manufacturers in the automotive industry and in the agriculture sector. This coating is perfect for priming of outdoor components with high requirements prior to the powder coating or it can also serve as topcoat of galvanized products and products with zinc coating. The cathodic dip coating provides a cost-effective and high-quality protection whether we are talking about plate components in the engine compartment or about lock parts exposed to wear.

Our modern, automated and flexibly programmable equipment enables us to carry out even the surface treatment of demands in small quantity and of large series parts effectively. Powder coating of parts pre-treated by using this method (of parts with cathodic dip coating, zinc coating or of anodized parts) or surface treatment of raw parts – following their integrated degreasing – are also possible.

Due to the nature of the technology even coatings and colors according to individual customer requirements are possible. Areas of application are: outdoor automotive components, construction products.

In addition to powder coating, we made also the application of wet paints (solvent-or water-based ) under standard conditions possible by increasing the flexibility of our automated paint sprayer. In the painting cabine integrated in the conveyor system we are able to apply mainly zinc flake coatings (Dörken and MAGNI) and polymer coatings (TempCoat , ChemCoat) to hanging parts. The combination of coatings and applied spraying method allows the use of low layer thicknesses (20-50 µm) and it offers cost-effective solutions, in addition to fulfilling the features expected from the coating. Areas of application: brake parts for automotive and railway vehicles, parts of agricultural machines, fasteners for wind turbines, springs ,parts of food processing equipment.

By using this service the surface treatment of products will be possible that are – on account of their quantity, complex geometry, special treatment or on account of special nature of the coating itself – not suitable to be prepared on automated equipment.
