Quality is the trademark of the work companies within the holding company. Quality is therefore embedded in the control of the raw materials purchased. They must satisfy certain specifications made known at the supplier beforehand. On the arrival of the material, one or a number of samples are taken for analysis and it is checked if the material is properly packed. If the material is granulate, turnings or chippings we melt the sample and cast it into a pill shape. We analyse the pill with the most advanced X-ray spectrometer (XRF). Parts can be analysed with our XRF gun, or we carry out the analysis on an AAS spark machine.
