Welding

Manual welding is provided by highly qualified workers using various types of welding equipment such as the MIG/MAG, TIG, CMT. A GOLEM 1200 is used for submerged arc welding. Welding of rotated assemblies and booms is done in particular by welding robots IGM and OJ 10. We use welding materials: Class S235 to S960 (Weldox 700, Hardox 400, Armox 500) and have special types of steel (size 1 – 150mm). PPS Group a.s. (a joint stock company) holds the following welding certificates.

Surface treatment

Depending on parameters of the products and client requirements we provide wet painting, especially with 2K colours:Depending on parameters of the products and client requirements we provide wet painting, especially with 2K colours:
1. In the chamber painting line with tunnel pre-treatment, on the circular overhead conveyer, through intermittent motion.

2. In a separate painting and drying box and multi-mode painting cabin, on track cars and overhead groove, with high-pressure pre-treatment of the surface.

Sand blasting
PPS Group a.s. (a joint stock company) offers a complex surface treatment with sand blasting and painting processes. The company has an automatic sand blasting workplace, composed by sand blasting chamber HOLLAND MINERAAL and sand blasting robot BLASTMAN. The sand blasting production reaches around 225 m2/h at the operational pressure 8 bars and 19 mm blast tube. The robot sand blasting process can be programmed in advance or it is possible to program the robot for manual sand blasting (the robot memorizes and retrieves the manual sand blasting procedure). It is also possible to use manual sand blasting without the robot.

Painting line
The pre-treatment of the surface (degrease + iron phosphate coating, rinse and drying) is realized in the tunnel line through a shower system with Henkel products.

The consequent painting and drying of the primer and final coat is done in the separate painting and drying boxes. The primer coat is applied with low-pressure HVLP equipment TRITON 308, and the final coat with the high-pressure equipment 2K WAGNER TWIN KONTROL 35 – 70. The cycle time depends on the painting time, which is about 10 – 20 min, on 43 hangers. The painting products can have the maximal dimensions of 4 x 1.8 x 1.35 m and weigh up to two tons.
Separate painting and drying box
The pre-treatment of the surface (degrease + iron phosphate coating) is carried out with the high-pressure equipment RB- 30E and Henkel products. The primer coat painting is performed by the semi-pressure spraying equipment KREMLIN 20.25, and the final coat with the high-pressure equipments 2K WAGNER TWIN KONTROL 35-70. The products can have the maximal dimensions of 14 x 4 x 2.5 m and weigh up to ten tons.

Multi-mode painting cabin
The pre-treatment of the surface (degrease + iron phosphate coating) is carried out with the high-pressure equipment RB- 30E and Henkel products. A fully-automatic multi-mode painting cabin BLOWTHERM T1 performs the whole process of painting and drying. The dimensions of the painting cabin are 16 x 5 x 5 m and the track cars transport the parts. The primer coat painting is realized by the semi-pressure spraying equipment KREMLIN 20.25, and the final coat with the high-pressure equipment 2K WAGNER TWIN KONTROL 35-70.
