Complex LSR processing and industrial additive manufacturing
The German plastics processing machinery manufacturer Arburg will showcase two automated hydraulic and electric Allrounders and the Freeformer for industrial additive manufacturing at the Chinaplas 2017 (hall 5.1, stand A42).
These will produce smartphone covers from LSR, medical technology connectors and spare parts for the aerospace industry. Further Allrounder applications featuring medical technology and LSR processing will be presented by Hekuma (hall 12.1, stand J41) and Mehow (hall 4.2, stand D01). The fact that entry-level hydraulic machines are suitable for complex LSR processing tasks will be demonstrated at the Arburg stand by a hydraulic Allrounder 420 C Golden Edition with a clamping force of 1,000 kN. The machine produces flexible LSR covers for the iPhone 6 in a cycle time of around 25 s. The parts weigh 21 g. The mould is provided by Prover, while the LSR dosing unit comes from 2 KM. A Multilift Select robotic system performs the handling tasks. Mehow will also present an LSR application. There, a turnkey system built around a hydraulic two-component Allrounder 470 S with a clamping force of 1,100 kN and two size 170 and 100 injection units produces wine bottle closures using a hard/soft combination (PC/LSR). Handling is performed by a six-axis robot in this case.
Although Chinese customers mostly use the Freeformer for product development purposes, Arburg will demonstrate the potential of industrial additive manufacturing of functional parts at the trade show. Here, a Freeformer produces a spare part from PC for the aerospace industry. Using 3D CAD data as a basis, the parts are produced from inexpensive qualified plastic granulates using Arburg Plastic Freeforming (APF). The Freeformer is equipped with two discharge units as standard. This enables it to process an additional component in order, e.g., to manufacture a part in different colours, with special tactile qualities or as a hard/soft combination. Alternatively, it can be used to build structures from a water-soluble support material, enabling complex part geometries to be realised.
