The cube technology that Arburg is presenting at K 2025, October 8 to October 15 in Düsseldorf, Germany, on its stand 13A13 with an Allrounder Cube 1800 is definitely worth seeing. The cube machine produces two-component caps for the personal care sector. The higher investment in equipment usually pays for itself quickly because it can reduce cycle times and increase productivity significantly. The production cell is equipped with a space-saving Agilus six-axis robot, which removes molded parts and deposits them on a conveyor belt in an automated process.

Cube technology, which Arburg is driving forward on a joint basis with its partner Foboha, really comes into its own when standard machines reach their productivity limits.

Compact: Allrounder Cube 1800

The Allrounder Cube 1800 with a clamping force of 1,800 kN and a column distance of 570 mm x 570 mm has a very compact design. The cube machine is particularly suitable for the cost-effective production of technical molded parts, medical technology products and applications for the personal care sector, to name just a few examples.

The exhibit is equipped with a size 400 horizontal injection unit and a size 170 traveling injection unit. A 4+4-cavity demo mold from Foboha is used to produce two-color PP caps in a cycle time of around nine seconds. The Compact Cube is easily accessible from above for installation, removal and maintenance work. The cube is rotated servo-electrically, while mechanical gear racks perform the horizontal movement. Four frames are injection molded at station 1. After a 90° rotation to the passive side of the cube, the pre-molded parts cool down at station 2. After another rotation, the second component is molded at station 3. Finally, at station 4 — also cycle time-neutral — the finished parts are removed automatically and are deposited on a conveyor belt by an inversely mounted Agilus six-axis robot.

Cube technology: Space-saving and efficient

Arburg's cube machines are available with clamping forces of 1,800 kN, 2,900 kN and 4,600 kN. Injection molding in two parting lines arranged one behind the other as well as cooling and removal all take place simultaneously. The use of the passive sides of the cube alone significantly reduces cooling times. In addition to classic free-falling packaging applications, cost-effectiveness can be further increased through additional cycle time-neutral process steps such as the loading of 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 circumstances, an Allrounder Cube can replace several conventional injection molding machines, thereby reducing the space required by up to 75%.
