Overmolding collaboration creates unique water-testing tool


Public health authorities around the world now have an all-in-one, cost-effective tool to test water quality thanks to a highly automated approach rooted in an innovative two-shot overmolding process.

The technology was pioneered recently by Roembke Mfg. & Design (Ossian, IN); ENDETEC (Kingston, ONT), a water sensor and monitoring company; and Engel Machinery North America (York, PA).

The product is a turnkey single-use water test cartridge system and automated monitoring system that determines water quality within 2 to 18 hours depending on level of contamination. It replaces a test that can take up to two weeks to determine the presence of E.coli and total coliform bacteria. Total coliforms include bacteria that are found in human or animal waste.

Development work started three years ago and led to innovations in polymers used, tooling, injection molding machinery and specially developed automated assembly equipment that completes six processes outside of the molding area, and then boxes the cartridges for shipment....
