Connectors and cases to house electronic equipment for the automotive and electrical engineering sectors are the daily fare of Fischer GmbH & Co KG, based in Sinsheim, Germany. Erich Fischer, Head of Production at Fischer, is familiar with the challenges posed by injection molding thanks to his lengthy experience in this field. For ten years now, cavity pressure monitoring with sensors and systems from the Kistler Group has provided the reliable basis for his inspection work.
Erich Fischer and shift leader Martin Weinzettel, a qualified industrial specialist in plastics and rubber technology, accept no compromises when it comes to the quality of their injection-molded parts. They know that any defects will either cause problems when assembling components in their own operation, or complaints from the OEMs and Tier 1 suppliers who take delivery of millions of their products. Fischer has identified molds that are not completely filled (or 'short shots', as they are known) as the key criterion for the quality of injection-molded parts. Several years ago, Fischer introduced additional process monitoring based on cavity pressure to deal with this specific issue. So Fischer can rest assured its that molded parts meet the quality requirements:
"Now we have reliable protection against spiraling costs thanks to cavity pressure monitoring."
