For Boy Machines Inc. (Booth S50054), NPE2009 marks the North American introduction of its energy-sipping E-series of injection molding machines and the line of tiny XS presses, with just 11 tons of clamping force.
The Exton, Pa., company is showing a total of nine injection presses this week in Chicago.
Boy has grouped five XS machines together in a production cell at its booth to demonstrate that the small press is ideally suited for single-cavity, sprueless injection molding. The presses are molding components of a personal-care kit, which includes a two-part case and three items. The parts free-fall to a common conveyor, which moves them to a table for assembly and distribution to NPE visitors.
In a micromolding application that features a vibratory sprue separator, a sixth Boy XS is molding tiny gear housings.
A vertical Boy XSV with a vertical clamp and vertical injection unit is making nail files to demonstrate insert molding.
Boy also is rolling out its E-series to North America by showing a 99-ton Boy 90E. The U.S. company's European parent, Dr. Boy GmbH & Co. KG of Neustadt-Fernthal, near Bonn, Germany, first showed the energy-efficient machine at the Fakuma show held in October 2008 in Friedrichshafen, Germany.
The presses use a servoelectric motor drive to run the hydraulic pump. That means the motor only delivers power to the pump when needed; it switches off when no pumping action is required.
At NPE, Boy is running a three-plate, four-cavity cap mold on a 90E press with 99 tons of clamping force. Boy claims the pump uses 50 percent less energy than Boy's standard hydraulic pumps and runs more quietly.
Real-time energy consumption is being monitored and displayed on a large screen.
Boy also is demonstrating liquid silicone rubber molding on a Boy 35A press with 38.6 tons of clamping force.
All nine Boys are equipped with the Procan Alpha Control. Booth visitors can observe remote monitoring and control via an Internet connection to a press that's molding parts at Boy's U.S. headquarters in Exton.
