Available technology - effective and flexible operation
Our paint shop is equipped with two automatic lines that ensure fast, efficient and precise coating of products in both small and large series. Thanks to advanced technology, certified processes and an experienced team, we offer reliable solutions for industrial, construction and special projects.
Automatic line 1 - efficient coating of large volumes
This fully automatic line is designed for fast and high-quality coating of a wide range of parts with maximum dimensions of 3 x 2.4 x 0.7 m and a weight of 280 kg per hanger. Thanks to its high capacity it can coat large quantities of parts at once and thus shorten production time. The line includes fully automatic powder application and two manual workstations for pre-spraying and finishing of details and more complex shapes.
The key to a long service life is the five-stage chemical pretreatment of aluminum:
- degreasing + deoxidation (material removal 1.5 g/m²)
- rinsing with water
- rinsing with demineralised water
- Ti passivation - a protective layer ensuring long-term stability of the surface
- rinsing with demineralised water
The line allows the application of the full spectrum of RAL shades and is certified for the application of Livingsurfaces special paints.
Automatic line 2 - one of the largest in the Czech Republic
It allows coating of aluminum, steel and stainless steel up to dimensions of 9.5 x 2.4 x 1.2 m and a weight of 2500 kg. The line has a multi-chamber design where individual technological steps, such as pretreatment, drying, powder application, and firing, are independent and individually adjustable. This concept ensures flexibility in setting individual parameters for the best possible solution to your technological requests. The effectiveness and flexibility provide sufficient capacity for other projects. We currently have 40% free capacity, which can be increased while maintaining the current technology.
Our main powder coating process is accompanied by other technologies:
- bonding in a separate room with a controlled environment to ensure cleanliness and control over the bonding maturing process
- wet painting in a painting box with 2*4*3 m dimensions
- mechanical shop
- minor assembly including the application of isolation materials
Blasting and sandblasting
To completely remove impurities, rust and scale we use blasting with steel shot. This method guarantees an even roughening of the surface, which helps better adhesion of the coating or subsequent surface treatment. For products after hot-dip galvanising we perform sweeping - a fine blasting of the surface that ensures optimal adhesion of powder or wet coatings without damaging the zinc layer. For specific applications we also offer sandblasting with silica sand for fine cleaning of the surface, removal of old coatings or preparation of the material for further treatment.
Testing the quality of applied paints is a priority. We have our own laboratory for basic mechanical and chemical trials. An accredited laboratory is used for complex testing.
Write to us!Types of Powder Paints
POPULAR AND PRACTICAL PAINTSPowder coating is currently one of the most favored paint types, gaining popularity mainly due to its practical usage. It is constantly ready for use and will last you several years if stored correctly. This industrial coating is made from a mixture of resin, pigments, etc. Our paints can be used to treat surfaces of different materials in interiors and exteriors.
- ● Epoxy
- ● Epoxy-polyester
- ● Polyurethane
- ● Polyester
- ● Acrylic
- Matte
- Glossy
- Semi-glossy
- Structural
- Metallic

Powder coating process
How powder coating works on automatic line 2:
-
Suspension and preparation of product
Suspension and preparation of product: The preparation of the product occurs before the powder coating process. Covering up parts of the product that are meant to be protected from the paint application. Suspension is either manual or with the help of forklifts up to the weight of 2500 kg.
-
Automatic rinse
Automatic rinse The first step is iron phosphating by spraying with jets in an automatic chamber. Phosphoric acid affects the metal and insoluble phosphates develop, they are bound in crystalline grids and have negative charges.
-
Drying
The last part of pretreatment is drying. The product is moved on an automatic lane into an oven with circulating air at a temperature of 170 ° C. The product surface has to be completely dry before powder coating.
-
Paint application
The paint application occurs after drying in an automatic spray cabin. Eight fully automatic spray guns apply the paint to the product. At the beginning and end, there is also a workstation for pre-spray or final spray of products with a challenging shape.
-
Firing
The parts are routed to the hardening chamber oven after applying varnish. The powder melts, merges, and bakes (chemically reacts) into a compact hard layer. The chemical reaction causes polymer linking providing the surface durability against distortion. Fans circulate the heated air circulates. The temperature inside the hardening oven is in the range of about 140 - 220° C. The firing time is from about 10 - 30 minutes. The parts can be sent to assembly or further expedition immediately after cooling down. Once hardened, the surface can no longer melt or flow.
-
Packaging and expedition
The finished product is prepared for packaging according to our customer and ready for further dispatch.
