Two industrial clerks, four cutting machine operators, one technical drawer and one industrial technician formed a team. As part of their training at Munsch Kunststoff-Schweißtechnik GmbH based in Ransbach-Baumbach, this team was tasked with designing a bend testing device that is able to test the quality of a plastic welded seam according to the pertinent regulation, DVS 2203-5. This involves a destructive test where the measurement results have to be recorded or documented.
The main criteria for the actual measuring process are, firstly, positioning accuracy and, secondly, zero clearance of the testing device. Furthermore, special importance was placed on the following factors: freedom from lubrication and maintenance, robustness and long service life for the entire machine as it will be mainly deployed on construction sites.
