The solution
After a careful analysis with corresponding application trials, experienced specialists from WAGNER (Ursin Huwiler, Mats Rapp, Niels Ole Larsen, Janus Wemmelund), TRIAB (a Scandinavian system house provider of powder ovens) and selected powder coating manufacturers developed a flexible system concept that was installed at Brandt at the end of 2021.
With the electrostatic M-Line powder coating system, Brandt, as one of the first companies in the Scandinavian region, can also offer powder coating for non-metallic substrates. Non-conductive, temperature-sensitive materials such as plastics and even inhomogeneous natural materials such as wood are powder-coated with high efficiency in a material-friendly manner. To achieve this, the coating system can process highly reactive low-temperature powders and UV powders in addition to conventional metal powders.
The M-Line system comprises ideally matched components which ensure that different powder coatings can be applied with a high degree of efficiency, even on non-conductive materials. A core element here are the suction pipes arranged laterally along the coating booth on both sides, which minimize the air flow in the coating zone. WAGNER Field Controllers improve the grounding of electrically low-conductive workpieces, optimize the coating thickness distribution and prevent the so-called picture frame effect. The special geometry of the piping and monocyclone reduces the pressure loss in the system and the risk of powder deposits. This so-called Energy Efficiency Package (EEP) from WAGNER reduces powder friction during recovery, which generates less heat energy. This enables gentle recirculation of the highly reactive lowtemperature powder. Brandt uses the SuperCenter EVO powder center with Twin Sonic Sieve to control the complete system technology, including automatic guns and movement units. Powder feeding and color change processes are automated and very reliable.
