ALLROUNDER CUBE 1800: Compact CUBE-mould machine reduces cycle times

Innovative CUBE-mould technology significantly reduces cycle time. This increases productivity and quickly pays for itself despite the higher outlay on the mould. At NPE 2024, an ALLROUNDER CUBE 1800 with a clamping force of 1,800 kN will produce two-colour medical caps and demonstrate that a machine with a "compact CUBE" can significantly reduce unit costs even with smaller output quantities.

ALLROUNDER CUBE 1800 – compact and efficient

The ALLROUNDER CUBE 1800 has a clamping force of 1800 kN and a distance between tie-bars of 570 x 570 mm. It can be equipped with horizontal injection units in sizes 400 to 1300 and moving injection units in sizes 70 to 800. At its heart is a compact CUBE from partner company Foboha, which is easily accessible from above. The rotation of the CUBE is powered servo-electrically and the horizontal movement relies on rack and pinion mechanisms. An ALLROUNDER CUBE 1800 equipped with an 8+8-cavity mould can achieve more than twice the output of a conventional size 570 ALLROUNDER with a 4+4-cavity rotary mould working with the same mould mounting surface. The CUBE machine can replace two standard injection moulding machines – which drastically reduces the installation area. – which drastically reduces the installation area.

Compact CUBE – example of 2-component medical caps

The exhibit at NPE 2024, an ALLROUNDER CUBE 1800 with two injection units in sizes 400 and 170, uses a 4+4-cavity mould from Foboha to produce four two-colour PP medical caps in a cycle time of around nine seconds. Four frames are injection moulded at station 1. Having been rotated 90 degrees onto the passive side of the CUBE, the pre-moulded parts are cooled at station 2. After another rotation, the second component is injected at station 3. Finally, the finished parts are removed automatically at station 4. That sequence results in a fast cycle time for such a part of around 9 seconds. A six-axis robot places the finished parts on a conveyor belt and ejects any faulty parts detected by the control system. In addition, test samples can be removed at the touch of a button and set down in QA trays sorted by CUBE side for subsequent visual inspection of the injection moulded parts.

ALLROUNDER CUBE for short cycles and high productivity

The ALLROUNDER CUBE hybrid series combines speed and precision with reliability and energy efficiency. The CUBE-mould machines from ARBURG are available with clamping forces of 1,800, 2,900 and 4,600 kN. Injection moulding in two mould parting lines arranged one behind the other takes place simultaneously with cooling and removal. Just using the passive sides of the CUBE can reduce the cooling time by 30 per cent. Other processes that do not influence cycle time (including loading inserts, unscrewing, the assembly of individual components, integrated checks and automated parts removal, for example) enable cost-effectiveness to be increased further beyond that of conventional free-fall packaging applications.

Tailor-made complete solutions

Combined with a "smart" machine controller, the modularity of the ALLROUNDER CUBE series delivers high levels of flexibility and a perfect match to the mould technology. The robotic systems that are increasingly being used can also be integrated into the controller. At ARBURG, an interdisciplinary CUBE team consisting of colleagues from application technology, sales and automation to achieve very specific targets in the delivery of all aspects of "the CUBE". This means that customers who are interested in CUBE-mould technology can get custom-made complete solutions from a single source.
