Minka powder coating

Powder coating

Minka has been an expert in powder coating for almost 50 years. Thanks to our many years of experience, we are a reliable partner for the surface finishing of a wide variety of products.

Powder coating is a process that is mainly used for the surface refinement of metals. At our location in St. Lorenzen im Mürztal we coat, for example, gates, fences, window and door frames, window sills, railings, grilles, pipes, sheet metal, constructions and various small objects. Powder coating is also suitable for many other products made of aluminium, cast aluminium, bright steel, galvanised steel and stainless steel.

Thanks to our almost 50 years of experience in the field of powder coating, over a hundred business customers already place their trust in Minka. So far, we have been serving especially companies from the metal, steel, fence, door, window, façade and conservatory construction sectors, as well as locksmiths and glazieries.

How does powder coating work?

Powder coating basically consists of three successive work steps, which are mainly automated at Minka:

1. Pre-treatment

In order to optimally prepare the material for powder coating, the first step is a so-called pre-treatment. With the help of certain chemical and mechanical processes, the workpiece is freed from any dirt. In addition to cleaning, the pre-treatment is also necessary to increase the corrosion protection of the material. This ensures that the coated parts have a long life and that the coating adheres better.

Since the modernisation of our pre-treatment facilities in 2024, chemical dosing has been fully automatic and uses very little water. We have also completely eliminated the use of the environmentally harmful substance chromium.

2. Application of the powder

After the pre-treatment, the actual powder coating process begins. Special powder spray guns are used to apply the paint powder to the surface of the workpiece. The paint particles in the powder cloud are electrically charged and settle on the material. This creates an even layer of lacquer on the surface.

At Minka, we work with several automated powder coating booths. These ensure that the paint powder is applied evenly and efficiently.

3. Curing and drying

After the powder has been applied, the workpiece is placed in a so-called curing oven. There the material is heated to temperatures between 120 and 240 degrees for up to 30 minutes. This creates a resistant, long-lasting layer of lacquer. In technical jargon, this last step is also called cross-linking.

With the help of strict quality controls, we ensure that all three steps in the Minka powder coating process are carried out correctly. Because only if each step is carried out properly will the end result be an optimally protected and visually flawless product.
