Electronic fluid metering assembly, digital flow meter, metered fluid dispense
Getzner, GC material, polyurethane foam seal
One of PGC’s customer is a leader in advanced fluid handling and dispensing equipment, and they needed help with a new product that required an IP65 rating. With years of history together, we had a selection of materials in mind that could work in this new assembly. Thankfully, PGC is setup to get customers materials and prototype parts quickly for their IP65 water ingress protection testing needs.
There weren’t many bolts securing the assembly together, so the right combination of density and thickness were vital to seal the assembly without causing the fasteners to strip. PGC was accustomed to providing material and part solutions to this customer, but the only way to know how a gasket or seal would perform in this application was to test it in the assembly under environmental conditions. Testing would be crucial in order to distinguish which material, density, and thickness would work best.
With the customer’s design experience, and PGC’s inventory of material options, we teamed up to identify a set of material densities and thicknesses to begin testing. With the many methods of material processing available, PGC was able to quickly make a set of prototype gaskets from various materials. With the first set of prototype parts completed quickly, our customer was able to conduct testing, identify leak paths, and swiftly modify their design for additional testing.
After trials with the various densities and thicknesses, the customer was able to center in on the perfect seal for the application. Too thick or dense, and the assembly would strip screws. Too thin and light density, and there wouldn’t be enough crush to properly seal the electronic unit. With PGC’s ability to select from a vast inventory of material options, skive to exact material thickness requirements, and selection of machines for converting gasket and seal materials quickly, this fluid equipment customer achieved a winning combination of testing and production parts. Following up, the assembly ended up completing a more strenuous IP69 testing rating for even better performance and use!Download this case study
