SAND BLASTING

Merging of metal parts as a result of heating up and melting of the material at the point of joining. The source of heat is the welding arc. Welding takes place in a gas shielding, which has a direct impact on the efficiency and quality of welding.

PROCESS DESCRIPTION

Sandblasting aims to remove contaminants and to standardize the surface structure. It takes place in a closed cabin. The operator, who is outside, sandblasts the elements with a special gun, from which an abrasive material (sand) is released in a compressed air stream. The result is a rough surface free of dirt and corrosion.

We use it for sandblasting:

Cabin dustless sanding machine PK 1TONA with dust extraction unit ZO 250 P is designed for sanding small and medium size elements. Thanks to adjustable pressure it is possible to obtain different speed of sand particles, and thus the desired roughness and possibility to sand any surface. The sandblasting machine is equipped with a dust extraction unit which filters out the dusts generated during sandblasting. This enables precise sandblasting of elements with the finest details.

COOPERATION

PHOSPHATE TREATMENT

The process of chemical production of a protective coating on metal surfaces in order to protect them from corrosion and high temperatures. Thanks to the reduced friction coefficient, the coating is an excellent primer for paints and varnishes.

PROCESS DESCRIPTION

The elements subjected to the phosphating process are placed in a special container in which they are immersed in hot phosphate and phosphoric acid solutions. After being cleared of any deposits, the elements are transported for 10 minutes to an oven preheated to 110 °C.

We use it to phosphate:

A bathtub of phosphate and phosphoric acid solution and a bathtub of clean water, which have aeration, so that the solution reaches every place and all impurities are removed from the elements cleaned in water. The coating prepared in this way constitutes an ideal, anti-corrosion surface ready for further processing.

COOPERATION

AUTOMATIC POWDER COATING

The process of automatically applying electrified powder paint particles to the metal surface. The powder layer is maintained on the surface due to electrostatic forces. The electrification of the particles takes place by electrostatic spraying (high voltage method).

PROCESS DESCRIPTION

The process cycle in the paint shop consists of the following stages: loading of the parts, zirconium conversion, washing in ordinary water, rinsing in demineralised water, drying, painting, polymerisation, cooling and unloading of the parts. The use of automatic methods used in the painting process guarantees high quality and durability of the coating while maintaining an aesthetic appearance.

For automatic powder coating we use:

Automatic Painting House EURO 90 – is a painting line designed for painting metal elements with thermosetting powder paints. The paint shop consists of a surface preparation tunnel, drying oven, paint booth, firing furnace and a monorail conveyor. Finished products are characterized by high mechanical and corrosion resistance and obtain the desired gloss and shade. The whole process is automated.

COOPERATION

POWDER COATING

Manual powder coating is a process of applying electrified powder paint particles to the metal surface. The powder layer adheres to the metal surface due to electrostatic forces. The electrification of the particles is achieved using the voltage method and is carried out by electrostatic spraying.

PROCESS DESCRIPTION

The paint shop’s technological cycle consists of the following stages: loading of the details, preparation of the surface by bathing in hot phosphate and phosphoric acid solution together with rinsing in clean water and drying in an oven, painting, polymerization, cooling and unloading of the details.

For manual powder coating we use:

Manual paint shop – is designed for painting metal parts with high temperature curing powder paints. The paint shop consists of bathtubs for surface preparation, paint booth and baking oven. After hardening, the coating is characterized by above-average mechanical resistance and thanks to the phosphate coating, high corrosion resistance. Activities in the process of manual powder coating are performed by employees.
