The use of photogrammetry in improving quality of workpieces after an injection molding process

摘要

In the paper a possibility of utilization of modern measurement methods in production of plastic parts was presented. This was realized on an example of a bus seat manufactured by injection molding process. Coordinate measuring technique and its application range was briefly discussed. The results of static and dynamic photogrammetry were shown. Thermography was used to investigate cooling process of both: a mold and an object. Material that was used in research and to manufacture seats was also presented with its features and parameters. As it was shown in the research and analysis of results, thanks to utilization of modern measurement and analytic methods accuracy parameters of workpieces manufactured by injection molding process were significantly improved.
