When Tualatin, Oregon-based Plasti-Fab, Inc., landed a contract to cut hundreds of circles out of 8,000-pound fiberglass plates, they decided abrasive waterjet would best completed the job. The company had to find two things: a waterjet manufacturer capable of building a 14’x28′ waterjet table, and a system that could be installed outdoors-their building already had two CNC routers and there was no space available.
Plasti-Fab CNC Supervisor Wade Oxford explained that after researching several waterjet systems, only Jet Edge o St. Michael, Minnesota, was capable of delivering the large system they required. The company selected Jet Edge’s Mid Rail Gantry that features a rugged floor-mounted rack and pinion drive-rail motion system. The waterjet system, which is the larges in the Northwest, is powered by Jet’Edge’s 50-horsepower iP60-50 intensifier pump, rated for 60,000 psi.
Plasti-Fab installed the system under a steel awning equipped with a hoist, then added a swimming pool heater and retractable solar blanket to the waterjet tank to keep the water between 68 and 74 degrees year-round. Oxford says the Jet Edge waterjet system is hands-down much faster than cutting the parts with a hand router which yielded poor results after a week of tests.
