Our ALLROUNDER CUBE injection moulding machines are precisely adapted to cube moulds. Their servo-electric toggle-type clamping unit allows for high-speed cycles with reduced energy requirements - the ideal basis for efficient high-volume production at reduced unit costs.
New ALLROUNDER CUBE 1800
In the "personal care" area of application, the new ALLROUNDER CUBE 1800 uses two injection units in sizes 400 and 170 to produce four two-colour caps per cycle, with a cycle time of only 8.7 seconds. The machine is equipped with a 4-cavity “Compact Cube” pilot mould from Foboha and processes chemically recycled PP produced by Borealis.
At station one of the cube mould, four frames (0.85 g) are injection-moulded. After a 90 degree rotation, the pre-moulded parts cool down on the passive side of the cube (station two). After another rotation, the second component (2.10 g) is injected at station three. Finally, at station four, a six-axis robot that is fully integrated into the machine controller removes the finished parts – also without affecting the cycle time.
CUBE technology saves 40 % cycle time
The new reverse cube system from Foboha for ARBURG's ALLROUNDER CUBE increases quality, accelerates cycle times by up to 40 % compared to two separate injection moulding machines plus assembly process, and offers enormous cost and floor space savings.
Using a 24+24-cavity cube mould with its halves arranged one above the other, an ALLROUNDER CUBE 2900 produces 24 PP bushings and 24 POM rollers simultaneously. The cycle time is around 9.5 seconds. The cube halves rotate by 90° against each other. While injection takes place on one side of the cube, the components on the other three sides cool down enough so that they can be assembled directly in the mould. Assembly of the individual parts to form complete rollers for dishwasher baskets is carried out by a six-axis robot.
Cube-mould machine for high-speed applications
The ALLROUNDER CUBE is specially designed for high-speed applications. With a clamping force of 2,900 kN and two size 800 and 400 injection units, it will produce two-colour flip-top closures from PP in a cycle time of 8.5 seconds.
With four usable sides and two parting lines positioned one behind the other, the 32+32-cavity cube mould offers key benefits: production of the pre-moulded part and the final product, as well as cooling and removal, are performed simultaneously. 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 moulded on in the third position. On the fourth side of the mould, the flip-top closures are removed without influencing the cycle time, set down on a separate station and capped. Finally, an optical quality inspection is carried out on the finished parts.
