Manufacturing


D&M has a dedicated and extensive workshop to manufacture our parts and systems in-house.

Our manufacturing and welding specialists are able to produce clean, complex products on our state-of-the-art machinery.

We are capable to produce vacuum chambers up to 4000mm.

Our systems are assembled, cleaned and tested in our cleanroom facilities.

 

Cleanroom
Many of our systems are assembled and tested in our cleanroom.

Techniques available in our cleanroom:

  • Assembly 20m2 with 3.2tons lifting capacity
  • Orbital welding
  • Testing:
    • Overpressure/pressure drop testing up to  15 bar (higher pressures on request)

Our strength is to create custom design and manufacturing of low volume, complex systems.  As a result of having a dedicated engineering team of vacuum specialists, we have created an innovative approach and process knowhow.  Important competences are: Creativity and out of the box thinking.

Our goals is simple: produce systems to fulfil customer-specific needs with value for money.

Techniques used:

  • Mechanical engineering(3D + FEM)
  • Electrical engineering (E-plan)
  • Pumpdown behaviour/calculations
  • Outgas calculations on mono and system level
  • Labview automation

Competences:

  • Specific know-how:
    • Specialized in vacuum technology up to UHV
    • Thin film deposition
    • Gasflow systems (MassFlow)
    • Handling/motion systems in vacuum
    • Masspectrometry and outgassing 
    • Automation of vacuumsystems: Heating/Cooling (sampleholders) up to extreme temperatures in vacuum

CNC Machining

Our strength is to create custom design and manufacturing of low volume, complex systems.

As a result of having a workshop of manufacturing and welding specialists we are able to produce clean and complex parts and systems from small dimension to big parts.

Materials that are manufactured are only Stainless Steel and Aluminium to prevent cross contamination and unwanted outgassing/evaporation.
 

Our goals is simple: produce systems to fulfil customer-specific needs with value for money.
