Powder coating
We have three automatic lines for powder coating and one robotic line.
Powder coating takes place in several phases: pre-treatment, electrostatic powder coating and baking in the oven.
Pre-treatment of the profile achieves a protective conversion layer that allows good powder adhesion and the stability and resistance of the paint to corrosion and negative atmospheric influence. After the pre-treatment and drying in the drying oven, the profile is powdered through an electrostatic process, after which the profile is baked.
Industrial robots with six axes of movement, high handling capacity and ATEX certification for zone 2, enabled even application of powder on profiles as well as application of powder on hard-to-reach places (holes and grooves). Perfect repeatability, high precision and high quality on different types of profiles is achieved with robots.

Baking at a temperature of 180 ° C melts the powder particles and triggers a chemical reaction of cross-linking or polymerization and the formation of a hardened layer. After the whole process, the profile is cooled down, packed and ready for delivery. The products are delivered in standard colours according to Feal's tone chart, and other colours can be delivered according to the customer's wishes.
Plasticization is monitored and controlled during all phases, and the quality of products is controlled in Feal's laboratory in accordance with the requirements of the international certificates of Qualicoat from Zurich and GSB from Düsseldorf.
Max dimensions of a profile which can be plasticized:
- Max profile length: 7.100mm
- Max profile height: 2.200mm
- Max profile width: 300mm
