Large hot runners offer plug & play convenience. (Injection Molding).Responding to customer requests, Mold-Masters Ltd., Georgetown, Ont., has made a number of enhancements to its Flex-Dura line of hot-runner systems. These custom systems are aimed particularly at automotive and other large parts. They have been redesigned for fast, trouble-free installation. They come pre-wired and pre-assembled for immediate mounting on the tool and fast start-up. "These are true plug-and-play systems," says a company official. Flex-Dura systems, which have factory-replaceable heaters, are now also more robust and durable. Features include a reinforced wire channel and new stainless-steel tubing for hydraulic and pneumatic pneumatic /pneu·mat·ic/ (noo-mat´ik) 1. pertaining to air. 2. respiratory. pneu·mat·ic adj. 1.

Also new is a separate device that "reads" pressure sensors A pressure sensor measures the pressure, typically of gases or fluids. Pressure is an expression of the force required to stop a gas or fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor generates a signal related to the pressure imposed. in each melt channel and adjusts the valve gates to equalize e·qual·ize v. e·qual·ized, e·qual·iz·ing, e·qual·iz·es v.tr. 1.

Extra-long nozzles (averaging 600 to 900 mm) allow for injection on the core side of the tool. In valve-gated systems, the hydraulic or pneumatic units are individually cooled to extend the life of the O-ring seals. Tel: (905) 877-0185, www.moldmasters.com |
