The machine, which provides a 570mm by 570mm tiebar spacing - will be producing a novel six-egg package developed by Solution B of Germany and marketed as the ChickBox. The box is produced in a 2+1 cavity mould in transparent PP and is decorated with an in-mould label (IML). The manufacturing process involves moulding of the
two separate lid components, which are filled from the vertical injection unit and decorated using IML. The container base is then moulded using the main injection unit, with the two top mouldings arranged left and right and connected with a moulded hinge. The complete container weighs 19g and is produced on a cycle time of 2.6s. Ferromatik will also show the second generation of
its all-electric Elektron machine design, which is available in sizes from 50 to 450 tonnes (a 50 tonne model will be demonstrated running an LSR application with an all-electric injection unit from Reinhardt-Tech- nik and a mould by Emde Industrie-Technik). The new version of the Elektron machine uses an
updated controller with a large 15-inch touch screen and dedicated function hard-keys. It has also been restyled, following the visual design cues of the F-Series models. With all-electric moulding machines becoming
increasingly popular in the packaging sector, the Foboha division of AdvalTech (Hall B3, Stand 3213) will demonstrate the full electric version of its “Cube” stack turning mould technology at the show moulding dosing closures on an F270 machine on the Ferrmatik stand. The 4 x 8+8 mould will be producing special PP closures that are designed to contain powdered additives and flavours for dosing into the beverage at the point of consumption. The dried additives are enclosed in a sealed chamber in the

closure during assembly. This seal is broken the first time the twist top is opened, dropping the powder into the bottle. This type of closure is designed for use with beverages such as isotonics, where active ingredients may display a short lifetime when dissolved in the drink. The all-electric F270 machine will be equipped with a secondary traversing injection unit mounted on the moving platen. The total shot weight for the eight closures is 88g – 11g each. Cycle time is 7.5 seconds. The production process comprises injection moulding of eight upper and eight lower closure parts on both of the Cube mould parting lines, followed by a rotation of 90˚. While the next injection cycle is taking place the upper and lower closure parts are being connected on the exposed Cube mould sides by a special removal and assembly unit. The finished assembled parts are demoulded by a servo-driven ejector. According to Foboha, the Cube mould technology
provides a 30% cycle time over conventional processes. The cavity-assigned assembly process also results in improved quality, the company says. Users of the full electric version also benefit from reduced risk of oil contamination. Hot runner controller specialist Gammaflux (Hall A7,
Stand 7311) will show its latest G24 temperature controller. The G24 is a compact controller that uses the company’s Triangulated Control Technology (TCT), which provides 50ms temperature sensing cycles, self adapting PID control and phase angle firing control. The controller is also said to be less costly due to a reduction in the number of components. Other features of the new controller include Gammaflux’s Mold Doctor trouble shooter and its Performance Monitoring unit, which is able to detect leaks and fault in the hot runner or manifold. Plasticising screw and barrel maker Groche Technik (Hall A7, Stand 711) will be showing its Longlife Screw technol-
