3D Printed Plug Prevents Material From Escaping
Fenner Drives discovered that pellets were accumulating and not reaching their destination within their extrusion system. They also found an air leak, which was producing unwanted moisture. These errors were impacting the performance of the extruded polyurethane material.
To gain access to the misplaced pellets, a technician had to manually remove a plate at the base of the component.
The solution to prevent this issue was to create a plug that filled up the empty space preventing excess pellets from gathering. This plug would also serve as a gasket to prevent airflow and moisture.
The plug had to be removable. The sides of the plug needed to each slope at a 2.5° angle to wedge inside the clogging area and maintain a snug fit. Because of this a metal solution would not have been possible.
With the flexibility and toughness of NinjaFlex, the engineering team was able to print the plug within a matter of hours, allowing the team less downtime and easy maintenance.
