Van Dorn Demag Corp. has introduced two new small-tonnage, injection molding presses, the horizontal-clamp Cadence machine and the vertical Newbury E Series. Cadence presses are the next generation of Van Dorn Demag's ET line.
Van Dorn Demag will show the Cadence at NPE 2000.
The hydraulic-clamp machines come in clamping forces of 28, 40, 55, 66, 90 and 110 tons. The company in Strongsville, Ohio, said the small machine is designed to mold precision parts for electronics, telecommunications and medical devices. The presses also are useful for running test parts and checking molds.
Cadence presses are based on the global platform for small presses developed by Van Dorn Demag's German sister company, Demag Ergotech GmbH. It has been modified to meet U.S. requirements and includes Van Dorn Demag's own Pathfinder controller.
Glenn Frohring, product manager, said Cadence presses have several standard features that are offered only as options on competing machines.
One feature is flexibility on the injection unit. For each tonnage size, three sizes of injection units are available, from 0.5-13.2 ounces. Also, each injection unit may be configured with three combinations of screws and barrels.
Cadence machines also use direct electronic control to run the hydraulic system's pressures and flow rates, which gives the machines energy-efficient, low- maintenance and precise operation.
Other features include generous spacing of the clamping unit, including removable tie bars, wide-open daylight and deep mold-open capability.
Frohring said the company guarantees Cadence machines will be free of hydraulic leaks for three years.
On the insert-molding machine side, the 35-ton Newbury E machine is an improvement of Newbury 30ARS presses. Van Dorn Demag said the C-frame, vertical machine is ideal for low-pressure vinyl molding, such as wiring harnesses, cord sets and connectors, plugs and grommets.
An updated Sigmatek controller comes in English and/or Spanish. The height of the modular injection unit can be changed quickly from 3.5-5.125 inches at the centerline, to handle different molds.
Frohring said customers wanted more room, so the company made the platen area wider, to accept mold bases measuring up to 10 by 12 inches. An open front on the clamp also allows for inserts that protrude.
