Technical drawings and designs
Our technical team is ready to offer our customers technical support services such as: creation of 3D models, drawing of construction documentation (technical drawings), processing of accompanying documentation and spare parts catalogues.
Designers and engineers process the drawings and models in the following programs:
AutoCAD, Autodesk Inventor.
Based on delivered technical documentation it is possible to process the required type of material by cutting, burning and sawing.
For burning metal sheets the company uses the oxygen-acetylene (Telerex and Picorex) and plasma burning machines (technical parameters are in chart below).

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.
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.
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.
