Van Dorn Demag Corp. has joined the all-electric injection press parade, announcing Aug. 14 that it is making a machine called the IntElect. The first model, with a clamping force of 110 tons, will be shown at Plastics USA in October.
The press maker in Strongsville, Ohio, began researching the all-electric press in 1999, studying competing technologies, according to Larry Doyle, IntElect product manager. The company plans to add 50- and 80-ton machines by the end of the year, Doyle said. Eventually, the product line will extend to 500 tons by the end of 2003.
Van Dorn Demag made an initial move into electrics a few years ago when it added an electric screw drive as an option on its traditional machines. The IntElect is the first Van Dorn Demag machine totally powered by electric.
Benefits include reduced energy consumption, cleanliness, quiet operation and precise, accurate operation, the company said.
Alternating-current servo motors run five functions: the clamp, injection, recovery, ejector and injection carriage. Power is transferred from the motors via ball screws and a belt. The presses use a five-point toggle.
Each machine will come with the choice of three injection units, featuring a quick-change screw and barrel.
Van Dorn Demag's Pathfinder control runs the electric press.
All-electric presses typically cost more than hydraulically driven machines, but Van Dorn Demag officials declined to talk about pricing for the IntElect.
They also declined to say whether Van Dorn Demag has lost sales because it did not come out with an all-electric press more quickly.
``It is a growing segment of the market; there's no doubt about that,'' said Scott Kroeger, marketing director. ``We certainly have identified a need out there. The customers have been driving this more than anything ... they have a need out there, and they're looking for electric machines.''
At the same time, Doyle said the company did not want to rush a machine to the market.
``We're coming up with a machine that's got a proven technology in it. Van Dorn doesn't want to be sending a machine out there that's not going to start out the right way,'' he said.
