Arburg will be present at the Industry Fair in Celje, Slovenia from April 4-7 with an efficient injection molding application: an Allrounder from the new electric entry-level Golden Electric series will produce a cover for a dog lead that can be worn around the wrist.
Arburg added the Golden Electric machine series to its range in spring 2016 with the aim of facilitating cost-effective entry into electric molded part production.
The new electric machines offer superior price/performance ratio thanks to consistent standardization, e.g. a fixed combination of distance between tie-bars, clamping force and injection unit size.
At the show, an Allrounder 370 E with a clamping force of 600kN and a size 170 injection unit will produce two covers in a cycle time of around 28.5s. These are components of flexibly extendible dog leads (Lishinu) and can be worn on the wrist like a bracelet, for example when taking exercise.
The exhibit operates with a two-cavity mold from Slovenian company Tehnomat. The finished acrylonitrile butadiene styrene (ABS) molded parts are removed and set down by a Multilift Select linear robotic system.
The Allrounder Golden Electric is available in four machine sizes with clamping forces from 600-2,000kN. The dual five-point toggle system ensures fast, high performance cycles. The play-free spindle drives operate with high precision. The position-regulated screw ensures high molded part quality.
The new electric machine series also features liquid-cooled motors and servo inverters and offers benefits in terms of energy efficiency, short dry cycle times and high reproducibility.
Compared to standard hydraulic machines, the high efficiency of the servo motors, continuous power adaptation and energy recovery during braking achieve energy savings of up to 55%.
The machines are also easy to maintain, thanks to swivelling injection units, plug-in cylinder modules and further improved lubrication and cooling.
The Multilift Select is the entry-level model among the linear Arburg robotic systems. It features servo-electric drives and is fully integrated in the Selogica machine control system. This means only one data set, a familiar approach during programming and synchronization of robotic system and machine.
Moreover, the teach-in function means that the Multilift Select is easy to program. Programming times and conversion procedures are thus efficiently shortened, handling sequences also become more reliable overall and training costs are lower.
