Quality assurance

A commitment to quality assurance creates trust

Our customers appreciate the experience and the consistently high quality of our work. It is a matter of course for us to check and document the products manufactured with CAD/CAM and CNC technology accordingly.

Other methods for quality assurance:

  • Feasibility analysis / manufacturability assessment, plausibility check
  • Initial sample inspection report according to VDA 6.1
  • Defect recording via SPC
  • Error evaluation according to Pareto principle, Ishikawa error analysis incl. action plan
  • Measuring equipment management
  • Workplace design according to REFA


  • 3D coordinate measuring machines:
    • Zeiss PRISMO navigator, measuring range 900 x 1200 x 650 mm,
      MPE: 0.9 + L/350 μm, Software: Calypso
    • Zeiss CONTURA, 800 x 1200 x 800 mm,
      MPE: 1.8 + L/350 µm, Software: Calypso
  • Height gauge Garant HC1
  • Contour measuring system optacom VC-10
  • Surface roughness measuring device Garant ST1
  • Hardness tester alphaDUR

Quality standard

Techtory - quality standard

Each and every one of us sees themselves as a quality assurance employee

The high quality of our work is our top priority. All production parts are tested according to their quality characteristics and the results are carefully documented.

For this purpose, we use the appropriate measuring technology with the necessary measuring equipment and measuring systems.

In this way, we always succeed in ensuring a safe manufacturing process and consistent quality of all our products.

Measurement technology for quality assurance

Messtechnik für die Qualitätssicherung

High quality equipment

We have optimal conditions for reliable quality control. We monitor the dimensional accuracy of our production parts with high-quality measuring equipment in an air-conditioned precision measuring room.

With the most precise measurement technology, the smallest deviations can be detected even on complicated contours.

All our measuring equipment is subject to permanent test equipment monitoring. Our measuring machines are calibrated at regular intervals to obtain reproducible results.

Documentation and statistics

lückenlose Dokumentation von Messdaten

Seamless documentation of measurement data

Our documentation is carried out in accordance with the principles of ISO 9001.

All measurement data is archived at a central location and used for statistical evaluations. Effective CIP measures can be derived from the results and manufacturing steps can be optimized.

We are happy to take over the documentation of measurement data, the preparation of initial sample inspection reports according to VDA and PPAP Level 3.

Project management, production and quality assurance work closely together with the aim of achieving continuous improvement in the production process.
