PRODUCTION, QUALITY AND DELIVERY

Together with our customers we work on projects from the very first idea to just-in-time delivery. We act responsibly and reliably using the latest tools, materials and operations. We emphasize quality, flexibility and consistency.

Based on digitized 3D technical drawings, we are able to prepare our own material with the use of new and precise cutting, bending and machining devices. Based on the materials used, we then choose the most suitable type of welding, which our experienced welders perform mostly manually. Of course, we use welding robots and automation where possible and expedient.

After welding, the structures are subsequently machined on robust machining devices. We are not a garage company that would be required to improvise. This is also evidenced by the fact that we produce bodies for the largest mining tipper in the world.

After tooling, the structures are directed to large-scale sanding and paint shops, where they receive the final surface treatment – again all according to customer requirements.

In some projects, we also provide partial assembly of components into functional units. As PPS Group used to produce complete construction, transport and mining machines in the past, we have experience in this area as well and in the future we would offer the assembly service to as many clients as possible.

Strict quality tests are carried out at every step of the production process and at the final stage of it. We measure and evaluate every single part, check every weld, angles, dimensions, colour depth – simply every single detail. We realize that our subcontracting for large international clients is directly involved in building their reputation and reliability of the final products.

Quality control of the products is carried out in three phases – initial inspection, in-process inspection and final inspection. Quality control of welds is ensured on the basis of certificates for performing non-destructive weld tests (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 control.

Calibration and testing laboratory

The calibration laboratory is capable of performing calibrating length, planar angle, temperature and pressure and measuring deviations from linearity and flatness according to International Standard ISO/IEC 17025: 2005. The test laboratory is capable of measuring linearity of rulers, flatness of control plates, and measuring geometric values and shape deviations on 3D coordinate measuring machines again in accordance with international standard ISO/IEC 17025: 2005.We provide calibration and testing laboratory services not only within our own company, but also for customers of other companies.

Metallographic laboratory and mechanical testing room

Metallographic laboratory secures the inspection of delivered materials through mechanical and metallographic tests. In addition it also performs metallographic analyzes of welded joints, tensile and bending tests at ambient temperature, impact tests at both ambient temperature and reduced temperature, and measurement of hardness of HBW, HV, HRC, HRB and micro hardness.
