The Stresstech Group Measurement Services are globally serving automotive and aerospace industries as well as universities and research centers with state-of-the-art equipment and highly educated stress specialists.
Stresstech Group is the only company in the world that can provide Barkhausen noise, X-ray diffraction (XRD) and Hole drilling (ESPI) measurements under one roof to cover stress measurements from a variety of materials.
At the Measurement Service laboratories X-ray diffraction method is used to measure residual stresses from crystalline materials and retained austenite content from steel. Barkhausen noise method is used to detect e.g. grinding burns or heat treatment quality from ferritic materials. The ESPI hole drilling method is suitable, in addition to the previously mentioned materials, for plastics and other kind of materials. Typically these technologies are applied in the quality control and development of treatment methods, such as: shot peening, heat treatment, grinding, machining or forming.
Proof of concept measurements are routinely carried out at the Measurement Service laboratories worldwide to investigate feasibility of customer cases before delivering measurement systems. Also the Measurement Service acts as a 3rd party quality control unit for a variety of industrial companies with fast delivery times and reliable results with high quality. The size range of the measured samples is from millimeter size dentist tools to bridges or railroad tracks. If the parts requiring analysis can’t fit through the laboratory doors field measurements can be arranged.
The measurement services available in the USA, Germany, Finland, and India are all following ISO/IEC 17025:2005 standard. Stresstech Oy Measurement Service XRD measurements are accredited by FINAS (T294) and the quality system is also ISO9001 certified. FINAS (T294) covers also on-site measurements.
