From the K 2016 onwards, the ALLROUNDER CUBE machines will round off the ARBURG range for high-speed applications using cube-mould technology. These special two-component machines are available in two sizes, the CUBE 2900 and the CUBE 4600. At the K 2016, the production of innovative closures for Pril washing-up liquid bottles from Henkel are being presented.
“For the ALLROUNDER CUBE, we’ve optimised the complete clamping unit, for example, including the servo-electric toggle, with regard to the cube-mould-specific requirements,” explains Andreas Reich, Senior Sales Manager Packaging at ARBURG.
Thanks to reduced dry cycle times, the cycle times can be reduced by up to a second and output increased by ten percent with the new cube-mould machines. The distances between tie bars have been increased, to 820 millimetres on the ALLROUNDER CUBE 2900 and to 1,020 millimetres on the ALLROUNDER CUBE 4600. A further advantage are the significantly larger mould installation dimensions of the clamping unit of maximum 1,900 millimetres on the smaller machine and 2,400 millimetres on the larger one. This means that moulds weighing up to 16 tonnes can be installed.
The new cube mould machines feature four servo-electric axes as standard: one for the clamping unit, two for electric dosage and one for rotating the mould. The injection units can optionally be driven hydraulically or electrically. The core-pulls for ejection and further mould functions are always hydraulic. This concept permits an energy requirement reduced by up to 45 percent compared to conventional hydraulic machines.
