Quality Assurance of Plastic Parts


To reduce mounting times, plastic parts are becoming more and more complex. In addition, miniaturization, elevated design demands, haptic feeling and fitting accuracy require small manufacturing tolerances. Above all, time to market needs to be short. Therefore, it is essential to conduct a fast and efficient inspection of injection-molded parts to verify tools, machine and process parameters and to control production. Coupled with complex geometries such as deep bores, undercuts and angled edges, conventional measuring machines come to their limits. Besides, decisions on the product quality cannot be derived from the measuring data, as problematic areas cannot be identified immediately. Therefore, a fast and efficient measuring system is highly in need to accelerate the inspection process.


Responding to the challenges above, ZEISS developed the optical 3D scanner ATOS Q, which delivers full-field measuring data of plastic parts in a short time. With its changeable measuring volumes, ATOS Q can be adapted to specific measuring tasks, depending on the size and the geometries of a part. ATOS Q features Blue Light Technology, which ensures the most accurate and repeatable measuring data. Even the smallest details can be taken for accurate and realistic evaluation, determining, for example, the correction values for the tool geometry (sink marks, warpage and shrinkage) and the machine and process parameters. The system also ensures production control, minimizing scrap and rework. Besides, scan data of multiple parts can be used for trend analysis. In addition, measuring data can be shared using ZEISS INSPECT.
