Considering the specifics of the produced sports equipment and the conditions and manner of its use, PESMENPOL has taken care to ensure high durability and resistance of the paint coatings. Therefore, the phase of spraying the powder paint and polymerization of the paint coating is preceded by the processes of abrasive blasting and chemical surface preparation of the elements. This is possible thanks to the possession of a modern automated technological line for powder coating, equipped with high-class machines and devices, the components and subassemblies of which have been compiled according to our own guidelines so that the processing effects meet the assumed quality parameters. Increasing the level of quality of protective coatings not only improves the aesthetic value of products, but also extends their service life and enables customization in terms of the colors offered. In the powder coating process, we use polyester paints of the highest quality.


Technological line for chemical surface preparation of elements and powder coating with a DEMI station and a batch sewage neutralization installation. Designed for processing structures and elements made of steel, hot-dip galvanized steel and aluminum. For the chemical process of surface cleaning, a tact spray washer with the following arrangement of process baths is used: degreasing and alkaline etching; rinsing in process water; rinsing in demineralized water; passivation applying a conversion coating for excellent paint adhesion; rinsing in demineralized water. The chemical treatment is followed by the process of drying the workpieces, evaporation of water and hardening of the passivation. After drying, the cooled elements are sent to the next stages of the technological process. The application of paint coatings with the powder coating line can be carried out in parallel in two painting cabins: automatic and manual. Automatic guns maximize coating efficiency. Two through-feed chamber ovens are used to melt and harden the powder coating. The maximum size of workpieces to be painted is LxBxH=7500x800x1800 mm for an automatic cabin and LxBxH=7500x1200x1800 mm for a manual cabin. All operations performed in the technological process are carried out using specially designed inter-operation transport. The workpieces subjected to individual processes are suspended on the beams of the an overhead, tact transport system. It allows elements to be carried through subsequent process phases with one loading. After hardening of the paint coatings, the prepared elements are cooled before being transferred to the pre-assembly plant.

The chemical surface preparation process provided includes:
Degreasing / etching -> Rinsing (tap water) -> Rinsing (DEMI water) -> Zirconium passivation -> Rinsing (DEMI water) -> Drying

Fully automatic process of application and polymerization of paint coatings includes:
Powder coating -> Coating polymerization -> Cooling

Inter-operational technological transport carried out using a suspended transport system


Abrasive blasting chamber with operating equipment, located as an internal facility of the production hall, with acoustic and thermal insulation. Designed and intended for cleaning steel structure elements from oxides remaining after laser cutting, metal filings and other contaminants, as well as all corrosion products and old paint coatings (in the case of product regeneration). The dimensions of the chamber allow for the processing of large-size structural elements with dimensions up to LxBxH= 7500x1200x1800 mm. The cleaned elements are loaded into / out of the chamber according to the PESMENPOL solution – on the track.

Proper preparation and cleaning of components for further processing in the abrasive blasting process is extremely important to achieve the desired final product quality. The hook-type rotary shot blasting machine is designed for cleaning, removing corrosion, mill scale and impurities occurring on the surface of steel elements, solid materials and simple welded structures with the use of reusable abrasive. Cleaned elements with a maximum size of 1300 x 1600 mm are introduced into the working space by means of suspended running tracks. Two independent carriages with hooks allow the preparation of the next batch of elements during the ongoing blasting process.

Machine structure made of high-quality manganese steel.
Double-leaf door opened/closed by means of pneumatic actuators.
The design of the rotor allows for additional adjustment of the direction of the shot streams in relation to the workpieces.
Frequency converters allow for smooth regulation of the energy of the ejected shot by changing the rotational speed of the turbines.
The abrasive separator combined with a bucket elevator and a dedusting system in the working chamber guarantees the cleaning of the abrasive from dust impurities.
