The CPAP generators used to provide newborns with a reliable air supply must be sealed as tightly as possible. The producer whr Hossinger Kunststofftechnik uses three different measuring strategies to ensure the precise manufacture of CPAP generators: contact, optical as well as via a chromatic white light sensor. Since the plastics processing company – located in northern Bavaria (Germany) – introduced the latest generation of the ZEISS O-INSPECT multisensor measuring machine, the company has not just been able to increase the precision of its in-house measurements. It has also shortened measuring times and will need to outsource fewer measurements in the future.
