Static and dynamic tests

Static and dynamic tests


OZ's Quality Control tests:

  • Chemical analysis on raw materials and castings
  • Ultrasonic Inspection to reveal defects and impurities
  • Air Tightness to identify any air leaks caused by porosity (wheel submerged in a tub of water, air enjected under 5-7 atm)
  • Dye Penetrant Inspection to identify any superficial cracks or microfaults (chromatic contrast under UV light)
  • Fatigue test wheel subjected to the same mechanical stress of a car driving along a bend
  • LBF Biaxial Wheel Testing Machine
  • Rolling test simulates the behaviour and reactions of the wheel along a straight stretch(maximum load, 100 km/h)
  • Impact test (crash test) simulation of stresses that the wheel might suffer on the road
  • Dimensional check to assess the dimensions, circularity and concentricity of the wheel (tolerances of a few tenths of mm)
  • X-ray control
