Quality Assurance

We assure our broadly based circle of customers a constant level of high quality, based on promised properties. Our claim is the delivery of faultless castings – that is why the quality assurance is a central part of each operation. The consistent process monitoring, starting with work preparation and ending with the treatment, guarantees a high degree of quality.  

The Quality of our castings is ensured by:

  • Spectral Analysis
    Continually analysis of the melt composition and comprehensive incoming inspections with a modern device of Spectro.
  • Dimensional Inspection
    The measurement of the geometric tolerances is fundamental for the following usage. With a 3D-measurementsystem of FARO we are able to check even complex castings.
  • Hardness Testing
    With the help of modern testing equipment we are able to check the hardness very fast and reliable.
  • Microstructure
    The valuation of the microstructure by qualified personnel guarantees the compliance of our customer specification.
  • Strength Testing
    For warranty of the quality we test the tensile strength with a Zwick universal testing machine.
  • Visual Inspection
    Our qualified personnel check all of our produced castings by visual inspection, to guarantee a faultless delivery.
  • Impact Strength Testing
    Especially for our brake blocks it is necessary to check the impact strength, to fulfil the customer specifications.
