Boy at NPE2009: Ultra-compact, ultra-energy-efficient

A new small injection system from Boy Machines Inc. might not seem surprising—small is what Boy machines are all about. However, take a look at the new Boy XS that takes its first bow at NPE2009 (June 22-26; McCormick Place, Chicago).

Leistritz extrusion labA new small injection system from Boy Machines Inc. might not seem surprising—small is what Boy machines are all about. However, take a look at the new Boy XS that takes its first bow at NPE2009 (June 22-26; McCormick Place, Chicago).

The 10-metric-ton clamp machine, which comes in both horizontal and vertical configurations, has a very compact footprint. The horizontal XS machine needs just 0.81 m2 of floor space, and the vertical Boy XS V asks for even less: 0.63 m2. Despite being so compact, the machines are designed for high precision, and even more surprising, for automation. The two diagonally positioned tiebars allow easy access to the mold area, and the ejector is also easy to get at. Both configurations come with 12-mm plasticating units and Boy’s Procan Alpha Controls, an optimum combo for micromolding.

Also in the Boy display you’ll find the new Boy 55 E and Boy 90 E injection molding machines, and what they are shrinking is your energy cost. The company says that, compared with current technology, the E Series machines reduce energy consumption by more than 50%, thanks largely to a servomotor pump drive that goes only as fast as the cycle phase requires. The drive technology also reduces the noise level by 20% from average. Boy says that the servo pump’s low inertia and quick response make the machine more dynamic and agile. It’s reported that the E machines can surpass the technical features of electro-mechanical molding machines, but at a lower investment cost. [email protected]
