Fakuma 2024: ALLROUNDER MORE 2000

The machines from the More series offer more space for larger moulds, rotary units, media connections and a usable ejector stroke. Thanks to their highly modular design and many optimised features for greater ease of use and simple maintenance, they can be adapted very flexibly to the respective customer and market requirements. This means that with the ALLROUNDER MORE, different types of processes can be combined with little effort and all common multi-component applications can be realised. As standard, the machines feature a highly dynamic electric toggle-type clamping unit with energy-efficient liquid-cooled servo motors, two electric injection units and a choice of 1,600 or 2,000 kN clamping force.

A fully electric ALLROUNDER MORE 2000 with a clamping force of 2,000 kN in the "Ultimate" performance variant will be used at Fakuma 2024. The two-component machine processes thermoplastic (PBT) and liquid silicone rubber (LSR) to create the kind of food-safe spatulas used for home baking. The machine is equipped with two electric injection units, sizes 170 and 400. With the smaller vertical injection unit, the handle is made of food-grade PBT (from BASF). The pre-moulded part rotates from the upper to the lower finishing station in the 1+1-cavity mould from Polarform via a servo-electro index unit with motor from ARBURG’s sister company AMKmotion. A horizontal injection unit is used to overmould the soft spatula component made of a non-tempered LSR (Wacker). The two components are injected directly and with no waste. A hot runner system is used for the PBT handle, while overmoulding with LSR is done by a servo-electric cold runner with a needle valve from Ewikon. The downstream cooling station sees the spatulas cooled down in a defined and precise manner. Surface structures are then accurately applied by a Rea laser station and, finally, the spatulas are deposited on a conveyor belt by a Yaskawa six-axis robot. Thanks to the systematic selection of materials and the automated process, the end product is ready for use in a cycle time of around 60 seconds. The spatulas in a hard/soft combination are suitable for use with food.
