Arburg will showcase cube technology at K 2025 on stand 13A13 with an Allrounder Cube 1800 producing two-component caps for the personal care sector. The compact machine combines multi-component injection moulding with automated part handling. The investment in cube equipment is positioned to pay back quickly because the concept shortens cycles and raises productivity when conventional set-ups reach their limits. The exhibit pairs an Allrounder Cube 1800, rated at 1,800 kN with a column distance of 570 x 570 millimetres, with a Foboha 4+4-cavity cube mould that produces two-colour PP caps in a cycle of around nine seconds. Part removal is performed by a space-saving Agilus six-axis robot that deposits finished parts on a conveyor belt. Arburg, working with partner Foboha, has long experience in multi-component applications, and the cube approach targets cost-effective production of technical moulded parts, medical products and personal care components.
Compact design and process sequence
The Allrounder Cube 1800 features a compact layout and is accessible from above for installation, removal and maintenance tasks. The exhibit combines a 400 horizontal injection unit with a 170 travelling injection unit. The cube rotates servo-electrically, while mechanical gear racks handle the horizontal movement. Production proceeds across four stations. At station 1, four frames are injection moulded. After a 90-degree rotation to the passive side of the cube, the pre-moulded parts cool at station 2. Following the next rotation, the second component is moulded at station 3. Finally, at station 4, finished parts are removed in a cycle time-neutral operation and deposited on a conveyor belt by an inversely mounted Agilus six-axis robot.

Cube technology and productivity
Arburg cube machines are available with clamping forces of 1,800, 2,900 and 4,600 kN. Injection moulding in two parting lines arranged one behind the other, as well as cooling and removal, all take place simultaneously. Use of the passive sides of the cube reduces cooling times. Beyond classic free-falling packaging applications, cost-effectiveness can be increased through additional cycle time-neutral steps such as loading inserts, unscrewing, assembly of individual components, integrated testing and automated part removal. With the same clamping area, a cube machine provides twice the number of cavities. Depending on the set-up, an Allrounder Cube can replace several conventional injection moulding machines and reduce the required space by up to 75 percent.
