                           Material testing                             since 1970

                                               Component Testing    

                        

Since 1970 we offer machines, modernisations and service for mechanical testing (destructive testing) and component testing like

• universal testing machines
  - tensile testing machines
  - compression testing machines
  - flexure testing machines
   

• hardness testing machines, hardness testers,
                                                                   portable hardness testers,
  - Vickers
  - Brinell
  - Rockwell
   

• impact testers for
  - Charpy and / or
  - Izod

• metallographic machines like
  - abrasive cutting machine
  - mounting presses
  - grinding and polishing machines
   

• microscopes
   

• specimen preparation systems
  - for sheet metal specimens
  - impact testing (notching)    for metals
  - impact testing                     for plastic
   

• DKD - calibration for
  - universal testing machines
                   tensile test machines
                   compression testing machines
                   flexure testing machines
  - hardness testing machines
                   Rockwel
                   Vickers
                   Brinell
  - impact testers

and a lot more around material and component testing

The comprehensive portfolio allows to offer you the mostly required equipment and service for destructive testing / mechanical test – one supplier for all –

For this we developed or choose machines from suppliers which are fulfilling high quality demands.

We are serving nearly all bigger and a high number of small industrial companies. This relationships are based on the reliability of the delivered machines and – not at least on the reliability of our service for material testing machines for tensile test, compression test, component testing, hardness testing, impact testing and metallography and equipment for destructive testing

  Our portfolio covers as follows:
- tensile test machines, universal testing machines, compression- / flexure testing
- hardness testing machines / hardness testers for Vickers Brinell Rockwell
- Impact tester, notching and / or milling machines for impact test ISO 179 / ISO180
- Metallography: Machines for abrasive cutting, disc grinding + polishing, mounting
- Microscopes
- Spectral analyses + X-ray analyses + applications, grinding + milling for OES + XRF
- Training and seminars for material testing

It is our target to advise you for the best solution for your testing requirements (even if we can’t serve you with our products. Often we are able to offer parallel different solutions. In nearly all ranges (from robotised systems down to simple applications) we offer the best cost/performance ratio:
From stand alone testing equipment up to full automatic test centres.

We are serving more than 1000 customers with more than 3000 testing machines. Because of our reliable Service we expanded to one of the biggest, independent company in the field of testing equipment in Germany and Europe.

We understand ourselves as a supplier of complete equipments and solutions for common requirements or customised solutions. It’s a pleasure to serve you with information’s and non-binding offers for a tensile test machine / universal testing machine for a tensile test / compression test / bending test, for metal – hardness testing with hardness testing machines, hardness testers, for tests according Vickers, Brinell, Rockwell, impact test for Charpy or Izod or the DKD calibration of this machines and specimen preparation solutions for sheet metal tensile specimens and notches for impact tests.

Each year we modernise about 50 - 80 testing machine und serve machines with repair and calibration jobs for following brands: Zwick, Wolpert, Instron, Test, Frank, Dyna-Mess, Erichsen, Hegewald & Peschke, MTS, Losenhausen, MFL, Mohr & Federhaff, Wolpert, CV-Instruments, Stiefelmeyer, Reicherter, Buehler, Leco, Emcotest, and other…
