Arburg Producing parts as one-offs or in small batches directly from CAD data
Germany – Under the motto "production efficiency from A to Z", Arburg will be exhibiting its comprehensive portfolio for efficient plastics processing.
According to the exhibitor, the focus will be on the cost-effective production of plastic parts, from one-offs to mass-produced items.
Among the company's eleven exhibits will be a complete micro-injection unit, an electric Allrounder 820 A and the freeformer for additive manufacturing. Unlike conventional additive manufacturing techniques, with Arburg Plastic Freeforming (AKF) standard granulates are melted as in the injection moulding process, the company said. The Freeformer produces layer by layer from minuscule droplets. The discharge unit with nozzle remains stationary, while the component carrier moves.
According to Arburg, the AKF process is globally unique and makes use of 3D CAD files, which are read in directly by the Freeformer. After start-up, everything else takes place automatically, the company explained. A nozzle closure with piezo technology builds up the desired component layer by layer. A 3- or 5-axis component carrier moves the part, Arburg said.
The two Freeformer exhibits will have a 3-axis component carrier and two discharge units in order to produce plastic parts from two different materials. The supplier said the focus will be on two-component parts and products with supporting structures that can be subsequently removed in a water bath or by mechanical means. The Freeformer will be integrated in the “Industry 4.0” project, which involves the production of customised moulded parts.
