Vacuum assembly

SDMS has extensive experience in heat treatments (volume or surface) and advanced vacuum assemblies (brazing, induction, or diffusion).

The company has specific means for these techniques:

  • Vacuum brazing furnace: 0.8m3; max. 10-5mbar vacuum at 1,500 °C
  • Vacuum brazing furnace: 1.5m3; max. 10-5mbar vacuum at 1,300 °C

Non destructive testing techniques

SDMS has expertise in non destructive testing techniques commonly used in their sectors of activity. The company has high-performance materials for each of the techniques used (3D, LT, PT, and RT), with accredited COFREND II operators.

See our skills
  • Three-dimensional (3D) testing: 2 Faro arms (scope: 3.2 m, ultimate precision: 0.07mm in clean room); and a Faro laser tracker (scope: 30m, precision: 0.02mm)
  • Helium leak tests (LT): 2 PFEIFFER helium leak detectors with 10-10mbar.l/s sensitivity; and two INFICON TRANSPECTOR 1 spectrometers with 0-100u and sensitivity 10-14a
  • Liquid penetrant tests (PT): a reserved workshop area for these operations
  • X-ray radiographic tests (RT): a nearby isolated bunker equipped with an RX MECASERTO 160KV - 30 mA
  • Ultrasonic controls (UT): US KRAUTKRAMER 5MHz transducers
