All Electric drive concept extended

Engel has now extended the scope of its all-electric drive concept to include multi-component injectionmoulding (Engel “Combimelt” technology), thus enabling user of this technology to achieve aneven higher standard of product quality. The new ENGEL E-MOTION Combi series comprisesfour basic machine sizes with clamping forces of 1,000, 1,500, 1,800 and 2,800 kN.They can each be equipped with up to three injection units. The “correct” choice of injection moulding machine and/or drive technology for a particular application is of decisive importance for the desired quality of product. The advantagesof servo-electric drives when it comes to the injection moulding of precision parts are meanwhile undisputed. Compared with hydraulic machines, the main advantages are: >> a clear saving of energy through much higher efficiency of the drive system and,more importantly, >> extremely high reproducibility of all machine movements and negligible temperature dependence through direct and rigid power transmission. A practical comparison with a hydraulic ENGEL VICTORY, for example, has clearly proved the ENGEL E-MOTION’s superiority asregards reproducibility: the servo-electric drive of the ENGEL E-MOTION achieves a meteringaccuracy of +/- 0.02 mm and a holding pressure accuracy of +/- 0.5 bar. In order to make these advantages available for a much wider range of applications and, by the same token, a much larger circle of users, Engel has now extended its range of all-electric injection moulding machines to include multi-component technology. Since the middle of this year,the new ENGEL E-MOTION Combi,equipped with a 1,000 kN tiebarless clamping unit, hasbeen available as standard. All its main and secondary movements are servo driven.The E-MOTION series meanwhile covers the entire range of small and medium-sized machines between 550 and 2,800 kN. The lower clamping force range up to 1,500 kN is covered by three tiebarless machines, These machines afford plenty of useful, unrestricted space for complex automation equipment – and the same goes for the new E-MOTION Combi machines with clampingforces of 1,000 and 1,500 kN. The E-MOTION machines in the higher clamping force range (1,800 to 2,800 kN) are equipped with a newly designed tiebar toggle clamping unit. A 3,800 kN machine will be added to this range in the spring of 2007.
