From the life of an exhaust system: further testing
Pierburg s.r.o., 2011
Owing to its expertise and proven track record of testing projects, Deimos was awarded a Pierburg contract. The interesting thing is that Pierburg continues producing the AGR exhaust system that was initially manufactured in a Visteon plant (here and here) with machines made by our company. Cleaned and packaged components are delivered to the plant where they become part of a larger whole with the help of a DSM screwdriver system. The assembly quality has to be double-checked with an overpressure test that takes place at a workstation also supplied by Deimos.
While the assembly and mounting are performed by an operator, the DSM screwdriver is a highly intelligent tool that monitors the number of moves, the number of screws as well as their position and of course measures the time, thus ensuring the ideal tightness of the screw. The assembled part is then tested by the operator fastening and then pressurizing it. The assessment unit analyzes sensor data and decides whether the assembled part does not leak. In this stage, Deimos software is used that has been developed for testing and assessment procedures. The process is controlled by the PLC Siemens Simatic 300 control unit.
