Using a production cell centred around an electric ALLROUNDER 270 A, equipped with a micro injection module and a linear robot system, ARBURG demonstrates how shot weights of 0,008 g can be processed with a high level of process reliability. Four microfilters each weighing 0.002 g and featuring complex geometries are produced without any sprue before being set down by mould cavities.

The 4-cavity mould from Toolcraft and the hot runner from Günther Heißkanaltechnik are also optimised for micro injection moulding. Together with the linear MULTILIFT SELECT 4, this provides a flexible, turnkey solution for the reproducible production of micro-components.

In a cycle time of around 7 s, four micro-filters made of POM, each weighing 0.002 g, are produced. Since the process produces no sprues, production is efficient in terms of materials as well as costs. The robotic system, with a load of 4 kg and an ARBURG gripper, sets down the micro-components on a conveyor belt, separated by cavities. To prevent static build-up, the parts are blown off with ionised air by the gripper component. An ionising bar on the conveyor belt prevents any further build-up of static charge.

The Euromap size 5 micro injection module is versatile and has been optimised to deliver precision control of short travel strokes while also maintaining high filling dynamics. It can process standard granule sizes and is therefore suitable for all common materials. To process these plastics in accordance with the first-in, first-out (FIFO) principle, an 8-millmmimetre injection screw is combined with a second 15- or 18-mm plasticising screw for melting. This means that the material is fed forwards continuously from the feed point to the tip of the injection screw. The injection screw features a non-return valve, and it operates on the screw-piston principle. This enables even the lightest of shot weights to be achieved with high precision and short travel strokes.
