Demag extends line of hybrid and “all-electric” machines

Injection molding machine manufacturer Demag Ergotech is increasing its offerings of machines incorporating electric technology. The Ergotech EL-EXIS S series, which was launched at K’98 and now includes seven models ranging from 60 to 300 tonnes of clamping, will be extended with a 350 tonne version. The “S” series is equipped with electrical drives for plasticising and mold movements, and a high-speed hydraulic injection unit, providing a 40 percent average energy savings in comparison to all-hydraulic machines. It is targeted for fast-cycling, thin-walled packaging containers and consumer electronics.

Demag’s Ergotech EL-EXIS E machines feature electric drives for all main movements and an integrated hydraulic power pack for secondary movements such as core pull and ejection. The auxiliary hydraulic unit uses only 1/10th of the oil required for an all-hydraulic machine and the “E” series provides an overall energy savings of 45 to 55 percent in comparison to hydraulic machines.

A prototype of the machine was introduced at last year’s NPE and since then the company has sold about 15 to 20 of the machines with clamping force of either 100 or 200 tonnes, according to Gerd Liebig, head of marketing. At K 2001 the company will launch a line of five models ranging from 60 to 200 tonnes in clamping force. A 100 tonne EL-EXIS E will be producing an electronic connector in a four-cavity mold at the show.
