moldmakingtechnology.com 35 Youngblom learned about Die-Sep's portable Mold Water Leak Tester and invested in the system with hopes it would eliminate the issue. It did that, and more, he says. For one, the water leak tester allows his team to test the whole mold for leaks, not just the side being worked on. "We used to use air to test for water leaks, like many shops do, by plug- ging one side of the water line and using an air fitting with a pressure gauge attached, he says. What we found is the air typically won't flush that crud or loose debris that inevitably develops around O-rings and baffles and causes that leak. This is because it's not a hydraulic flush; it's a compressed air test and it doesn't flow. With the leak tester, water flows through the tool and it takes the debris with it." The leak tester is portable and fea- tures a 25-gallon, self-contained tank. It has 12 circuits, which covers a wide variety of tools, and a manifold that can be connected to a mold via water hoses, but Youngblom says users can add T-fittings to the lines to double the number of hookups. Larger molds typically have a manifold system that can be used to hook up as many lines as may be needed. There is also a water pump and a digital flow meter to show the volume of water being circulated. Once the hoses are hooked up to a mold, water can then be circulated throughout the tool under pressure to find leaks and to flush the water chan- nels. A micron filter on the back of the VIDEO: Simplifying Mold Open-Close short.moldmakingtechnology.com/die-sep machine traps any debris that may be in those channels, he says. Besides being very affordable, Youngblom says the water leak tester is a valuable tool that enables 3M to perform water jacket cleaning, leak testing and flow metering. "These three tests keep our tools in good working order, they keep the process cycle times on track, and they prevent premature tool wear. The biggest benefit is we no longer have tools coming back with water leaks," he says.
