Calibration and Testing Laboratory

We provide calibration and testing laboratory services not only within our own company, but also for customers of other companies.

The calibration laboratory is qualified to perform calibration of length, plane angle, temperature and pressure gauges and measurement of deviations from straightness and flatness according to the international standard ISO/IEC 17025:2005. The test laboratory shall be able to perform straightness measurements of rulers, flatness measurements of control plates and measurements of geometric quantities and shape deviations on 3D coordinate measuring machines in the same way according to International Standard ISO/IEC 17025:2005.

Metallographic Laboratory and Mechanical Testing Room

Ensures the inspection of delivered materials.

The metallographic laboratory ensures the control of delivered materials by mechanical and metallographic testing. In addition, it performs metallographic analysis of welded joints, tensile and bending tests at ambient temperature, impact bending tests at ambient and reduced temperature and measurement of hardness HBW, HV, HRC, HRB and microhardness.

Quality Management System

Certified according to EN ISO 9001 since 2005.

PPS Group is certified according to AQAP 2110:2017 (production of defence products ), STN ISO 3834-2 (quality system in welding), DIN 18800, DIN 15 018, DIN 4132, EN 1090-1+A1 (welding system for steel structures), DIN EN 15085-2 (welding of railway vehicles and their parts) and the company’s accredited calibration laboratory meets the requirements according to ISO/IEC 17025. The company’s environmental management system has been in place and certified according to ISO 14001 since 2013.

We work with our customers on projects from the first idea to just-in-time delivery.  We proceed responsibly and reliably, using the latest tools, materials and working practices. We emphasize quality, flexibility and consistency.

Based on digitized 3D technical drawings, we can self-prepare the material on new and precise cutting, bending and machining machines. According to the materials used, we then select the most suitable type of welding, which our experienced welders carry out predominantly manually. Naturally, we use welding robots and automation wherever possible and practical.

After welding, we then machine the structures on robust machine tools. We are not a garage company where improvisation is necessary. This is evidenced by the fact that we manufacture the beds for the world’s largest mine tipper.

After machining, the structures go to large-scale sand and paint shops where they receive their final finish.

For some projects, we also provide partial assembly of the components into functional units. As the PPS Group has manufactured complete construction, transport and mining machines in the past, we are also experienced in this area and would like to offer assembly to as many clients as possible in the future.

Strict quality tests are carried out at every step of the production process as well as at the end. We measure and evaluate every single part, check every single weld, angles, dimensions, paint thickness – simply every single detail. We recognize that our subcontracting to large international clients is directly involved in building their reputation and the reliability of their final products.

Product quality control is carried out in three phases – incoming inspection, intermediate inspection and outgoing inspection. The quality control of welds is ensured on the basis of certificates for carrying out non-destructive tests of welds (NDT tests – ultrasonic tests, magneto-powder tests, penetration tests and visual tests of welds). 3D coordinate measuring devices MORA 0150 and LEICA TRACKER are used for dimensional inspection.
