Precision That Saves Lives

The principle of the CPAP generator: oxygen-enriched air is delivered to the baby via a tube and is administered with slight overpressure. whr Hossinger combines the individual components of the CPAP generator using a connector system instead of an adhesive. Yet a generator is only airtight if the individual components have been manufactured with absolute precision. The challenge: wall thicknesses of only three tenths of a millimeter, tolerances of a few hundredths of a millimeter, freeform components with a complex shape and different product colors made quality inspection difficult, protracted and sometimes costly with the optical measuring machine this mid-sized company had available.

To reduce the number of measurements outsourced to external service providers and nevertheless guarantee a high level of quality, the company introduced the ZEISS O-INSPECT multisensor measuring machine in 2014. It combines three measuring principles in one machine. However, the volume of the measuring machine was still too small for the large workpieces manufactured at whr Hossinger. Therefore, the company seized the opportunity to play its part as a pilot customer of ZEISS in bringing the latest generation of the multisensor measuring machines to market. One of its outstanding features is a larger measuring volume of 500 x 400 x 300 mm.
