Tactile metrology
For the quick, precise checking of prototypes, initial samples and series production components. For example, quality control in the automotive sector, in machine tool and machinery manufacture, for precision mechanics, medical technology and plastics technology. Large batches with tight tolerances are also excellently suited to tactile metrology.
Optical metrology
Ideal for the quick acquisition and 3D digitisation of external geometries, complete component analyses of test pieces of any size. The spectrum of components includes prototypes, sheet metal parts as well as injection moulded and die-cast components, as well as battery trays. We digitise the component surfaces quickly, without contact and with a high point density.
3d computed tomography
We acquire complex internal and external geometries using 3D CT. With this digital image, we check the external structures and all internal structures non-destructively. Ideal for metrological evaluations, geometry comparisons, the analysis of wall thicknesses, pores, shrinkage cavities and other defects.

Precise results thanks to the latest technology
Precise measurements are only possible with high-quality equipment. For this reason, we at QA only use the latest measuring instruments and systems from the renowned manufacturers Zeiss, Mitutoyo and GOM. However, advanced sensors, high-quality components and the careful preparation of the measuring system in our range of equipment are only half the story. In the end it is our experts who, with their specialist skills and their experience, are able to meet all the challenges from our customers.
Applications for industrial metrology
No branch of modern industry can do without highly precise measurement and inspection methods. Industrial metrology checks prototypes and guarantees the quality of ongoing production processes.
AUTOMOTIVE
Tactile and optical metrology are essential for the highly precise inspection of standard geometries, freeform surfaces as well as geometric dimensioning and tolerancing on shafts, gearwheels and housing parts in the drive train. In battery technology, optical metrology is used for the 3D digitisation and measurement of individual battery components as well as battery trays. Using 3D computed tomography, it is even possible to digitise and non-destructively analyse individual battery cells.
Medical technology
Modern medical technology does astounding things to keep people healthy. For this achievement to be possible, extreme care is required during the production of medical equipment. The measurement of roughness and the depiction of surface structures as well as geometrical dimensional inspection are imperative for ensuring the safety of instruments, implants and stents.
Plastics industry
During the manufacture of injection moulded parts, industrial metrology ensures the quality of production processes and products by means of the highly precise measurement of standard geometries, freeform surfaces as well as geometric dimensioning and tolerancing. In addition, nominal-actual comparisons between design and workpiece based on CAD data are possible. During component qualification, the permissible distortion on the parts installed in the end-product is determined before the end-product is actually assembled.
Frequently asked questions
What is industrial metrology?
Industrial metrology, or production metrology, refers to all measuring activities that are necessary during the industrial production of a product. Here the focus is often on parameters such as dimensions and geometry, however the characteristics of the material from which a workpiece is made can also be analysed. The requirements on the accuracy of the measurement results are significantly higher than in everyday applications. For example, during the milling of a cylinder head a precision of a few hundredths of a millimetre is required; distances in the range of a few nanometres can be crucial on printed circuit boards. The result is, of course, completely different requirements on the measurement methods.
What is tactile metrology?
A component is scanned mechanically during a tactile measurement. Expressed in lay terms, the measuring machine "feels" the surface of the component using its sensors. Here, for example, surfaces and contours can be measured or the roughness of the material checked. Tactile metrology is used in particular if individual inspection features on components are to be measured precisely and only very small tolerances are allowed, both on random samples and for high quantities.
What is optical metrology?
Optical metrology is suitable for the quick acquisition of the external geometry of a test piece. With this type of inspection, a test piece is first digitised with a high point density by a 3D scanner using its high-quality optical components and then analysed. Because these processes are without contact and quick, they are particularly suitable for ongoing quality control during production and process control.
How does the "non-destructive analysis" of a component work?
Non-destructive analysis NDT is an inspection technique during which a component is analysed without affecting its structural integrity. The component inspected is not withdrawn from the manufacturing process and can be further processed if the inspection is passed. Industrial CT makes it possible for us to provide statements about porosity, defects, cracks, wall thicknesses and nominal-actual comparisons. Industrial computed tomography can also be used in areas in which optical and tactile measurement is not possible.
What is the difference between 2d x-ray inspection and 3d computed tomography?
During 2D X-ray inspection, the analysis is undertaken based on high-resolution X-ray images in which even details in the nanometre range can be identified. If a digital copy of a test piece is required or volumes are to be measured, three-dimensional methods such as 3D computed tomography are used. Technologies such as 3D nano-computed tomography are used for particularly small, complex test pieces.
