What happens if problems arise in the assembly of the lip balms plastic components?
What if waste is produced time and again in the screw assembly of the lip balm casing? The error analysis on site may take weeks, or even months. This is when a detailed screw joint analysis from the screwdriving specialists pays off. In his laboratory for screw joint analysis, application engineer Rudolf Schmidbauer is holding three plastic parts in his hands: the casing, the piston, and the spindle for the lip balm. During assembly, the piston is first inserted into the casing. It is actually the second step that leads to most problems. This is what the company DEPRAG SCHULZ GMBH & CO is now about to examine carefully by means of the screw joint analysis ordered by the client: the spindle is screwed into the preset threaded hole of the piston until the snap-on connection to the casing closes.
