Infusion Pump Glass LCD Screen
3M™ VHB™ Tape
A manufacturer of medical devices hired PGC to create a solution for fastening a glass LCD screen to the plastic body of an infusion pump, to help the device withstand the rigors of heavy use and daily cleaning. When the manufacturer approached PGC, they had already selected the material for testing: 3M™ VHB™ Tape. The tape met multiple project requirements:
3M VHB Tape was an ideal choice for the gasket. But the stretchiness of the material presented PGC with challenges. Thin walls of the part and tight tolerances of the plastic housing and LCD, made high-volume manufacturing and installation difficult. It simply couldn’t be applied by hand. PGC engineers would need to not only manufacture the part to customer specifications, but also make installation foolproof.
PGC engineers developed a special liner with two die-cut holes in the center, which align with locating pins on the infusion pump. They added a thin layer of plastic to the paper liner, to reinforce the holes and prevent tearing during installation.To install the gasket, you simply slide the holes onto the pins and peel away the liner.
The customer was very pleased with the gasket that had been engineered to their specifications. And they were thrilled that PGC’s creative solution would ensure fail-safe installation. Equipped with an easy-to-install gasket that created a strong bond and seal, the customer was able to send the pump into the final stages of our customer’s design verification testing.
