  • Quality assurance
  • Customer-specific tests
  • Product development
  • Prototype testing, defect and damage investigations, complaints
  • Assistance and consultancy to members of the Böllhoff Group and their customers providing expertise in materials and testing.

Mechanical-technical testing

  • Tensile strength and compression testing to 400 kNHardness testing
  • Screwing tests (torque, angle of rotation, preload force)
  • Adhesion factor analysis
  • Structural testing, metallography
  • Surface defect inspection
  • Sealing tests
  • Cleanliness testing
  • Vibration testing of fasteners up to M16 size
  • Continuous vibration testing up to 150 kN ± 75kN

Physical tests

  • Coating thickness measurement - X-ray fluorescence analysis
  • Optical emission spectroscopy

Chemical testing
