Cube-mold technology allows for the output to be more than doubled, reducing unit costs. This becomes apparent in the high-volume production of two-color flip-top closures. Our ALLROUNDER CUBE, precisely tailored to a 32-cavity cube mold, produces more than 13,000 parts per hour.
All required production steps run simultaneously in a cycle time of just 8.5 s: the first component produced is the 0.8-gram drop-shaped top section, which then cools on the second cube side, while the 2.4-gram second component is molded on in the third position. On the fourth side of the mold, the flip-top closures are removed without influencing the cycle time, set down on a separate station and capped. Finally, a visual quality inspection is carried out on the finished parts.
- Efficient high-volume production: specially coordinated ALLROUNDER CUBE with fast servo-electric toggle-type clamping unit
- Integrated 32-cavity cube mold: servo-electric cube-mold rotation and independent moving axes
- Flexible process optimization: Free programming of all mold functions via SELOGICA control system
- Turnkey solution for the packaging sector: ARBURG implements complete cube-mold systems in close cooperation with Foboha

Cube mould technology
With four cube sides available for production and two parting lines positioned one behind the other, mold filling, cooling and part removal are implemented simultaneously in cube molds. In addition, twice the number of cavities are available with the same mold mounting surface. This results in high production capacity.
The flip-top closures are produced on an ALLROUNDER CUBE 2900 cube-mold machine with a clamping force of 326 tons. The servo-electric toggle-type clamping unit and the integrated 32-cavity mold with servo-electric cube rotation enable fast cycles at reduced energy consumption.
to the cube mould machines
Multi-component injection moulding
The two independently movable injection units are horizontally arranged and travel above the movable mounting platen. The pre-molded parts are transferred precisely and rapidly via servo-electric cube rotation. The production sequence can be reliably optimized with the central SELOGICA control system.
to the process
The top priority is the common goal of always finding the most cost-effective solution. This calls for interdisciplinary expertise. As a technology and systems partner we cover a particularly broad spectrum and can offer you expert support for the implementation of your requirements.
to applications technology
to turnkey consulting
In close cooperation with Foboha, ARBURG implements complete cube-mold systems for high-quality injection molding in large numbers of parts. They are of particular interest when several machines using conventional technology are needed for the required sales volume. Doing the maths pays off.
