GM tasked Morgan Polymer Seals to collaborate with ITW to design a mechanical seal for a new capless refueling system in the Cadillac CT6. The custom seal system had to reduce hydrocarbon emissions, seal on the fuel fill-nozzle, and remain flexible at a temperature down to -40°C. This article looks at the design process and how successful seal design is achieved for an automotive application.

Vision inspection is a computer-aided visual analysis of manufactured parts to sort out any with defects, irregularities, or other quality control issues. Unlike manual inspection that relies solely on human hands and eyes, automated vision inspection employs a mechanical system of high-speed cameras, software, and automation hardware components to inspect each part thoroughly and quickly.

General Motors (GM) tasked Morgan Polymer Seals to collaborate with Illinois Tool Works (ITW) to design a mechanical seal for a new capless refueling system in the Cadillac CT6. The custom seal system had to reduce hydrocarbon emissions, seal on the fuel fill-nozzle, and remain flexible at a temperature down to -40°C. To avoid a larger redesign of the car’s body, the sealing system also had to fit within the sedan’s existing size constraints.
