The Engel e-mac tour 2013
Using two applications as examples, the full potential of the machine series will be demonstrated live at Engel subsidiaries. Most impressively, connector housings will be produced from fibreglass-filled PBT/ASA using an Engel e-mac 310/100 with integrated Engel viper 6 linear robot. Since the connector contacts are only inserted after injection moulding, competitiveness is determined by dimensional stability in this application.
From injecting and metering to mould and ejector movements, all drives in the Engel e-mac are servo-electric. This guarantees the high precision and process stability while maximising the effectiveness of the machine as a whole. The drives are operated by a modern axis system solution with stabilised intermediate circuit; braking energy is recovered and fed back into the grid, thereby achieving very high energy efficiency. The synchronous movements of the drive axes ensure fast cycle times and injection axis acceleration is more than 20 m/s².
The series has four machine sizes with clamping force of 50, 75, 100 and 180 tons. Thanks to the established CC 200 control unit in Engel injection moulding machines, the Engel e-mac offers full modularity and automation technology integration. The highly compact design of the machine saves space in the production hall and cuts operating costs at the same time.
