Powder coating is our core area of expertise and represents an effective and efficient process for finishing and protecting metallic surfaces. Typical substrates for powder coating are aluminium, steel and galvanised steel. In principle, all electrically conductive and 200 °C heat-resistant materials can also be coated.
We already look back on 20 years of experience in this area and have been able to gain a deep expertise in all matters concerning powder coating and surface technology during this time.
... creates the basis for a durable coating. At WK, the surface is chemically primed in 5-zone pre-treatment lines. This not only creates the ideal primer for any subsequent coating, but protects the material against corrosion.
In order to guarantee the very best pre-treatment and thus a high-quality coating to our customers, essential process data are continuously monitored and automatically controlled.
The Powder application
... refers to the actual coating process. An electrically charged powder cloud is created using high-voltage electrostatic pistols. The charged powder particles stick to the workpiece surface and form the powder coating layer.
WK has 4 modern powder coating booths in use.
The firing process
... is used for interconnecting the powder coating. The work-pieces are heated to about 180 °C in a furnace. This creates a resistant and uniform varnish layer.
After final quality checks (appearance, thickness, gloss, etc.), the coated workpieces are packaged for transport.
