Drum spraying is a hot-drum process, which is used for coating small components in a closed spraying chamber (Rotamat®).
During this efficient and cost-effective process the small parts that are to be coated are poured into a rotating drum, which is enclosed by a housing. One or several spray robots are used for spraying the coating material evenly on the parts, which are rolling around each other and can be comprised of different materials.
The coating material, which is applied with little loss, dries on the tempered parts during processing so that a visually homogenous surface is created. After the coating is finished, the parts can easily be removed from the swivel-mounted drum. Curing or finishing of the coated parts is unnecessary.
antifricor® - Multifunctional solid lubricant
With antifricor
®, Impreglon offers an approved combination system to optimize friction, wear and lubrication of moving components. Reduced friction with antifricor® leads to a longer serviceable life (Refer to the illustration below).
antifricor® is suitable for all applications in which friction reduces functionality and durability of components. Wear resistance, dry lubrication and corrosion protection are combined effectively in one coating system.
antifricor® is used by almost all automotive manufacturers. Typical parts are hinges, door locks, door stays, door handles, adjustment systems, fittings and other fasteners.
| Coating thickness: | 10 to 20 µm |
| Temperature range: | -200 °C to +430 °C
(depending on application) |
| Corrosion resistance: | 96 h to 720 h
(salt spray test according to DIN 50021) |
| FDA approval: | n.a. |
Delta MKS® - Powerful corrosion protection with zinc flakes
Delta MKS
® is a corrosion protection coating system applied with the most modern application methods - dip spinning, dipping and fully automatic wet spraying.
The surface treatment is free of chromate (Chromium-VI), and the zinc flakes provide galvanic protection. Hydrogen-induced corrosion, occurring when zinc is applied with electroplating, is not an issue. Sealing systems developed specifically to complement the functionality enable good sliding and nonstick properties.
Delta MKS® coating systems are mainly used in the automotive industry and in applications where outstanding corrosion resistance has to be combined with other functional and decorative requirements of international automotive manufacturers.
Coating thickness: 5 µm to 30 µm (depending on coating specification)
TempCoat® - Wear resistant slide coatings with nonstick properties
TempCoat
® is a fluoropolymer coating characterized by outstanding nonstick and sliding properties.
Additional reinforcement layers increase the wear resistance in combination with sliding properties.
TempCoat® surface treatments can be applied on aluminum, steel, stainless steel, copper, ceramics and even plastics.
| Coating thickness: | 10 µm to 100 µm |
| Temperature range: | -40 °C to +285 °C |
| Surface roughness (Ra): | down to 1.0 µm |
| FDA approval: | yes, for some types of coating
