Efficient mass production: Syringe barrels on electric Allrounder EWith the manufacture of threaded syringe barrels, Arburg demonstrates how quality disposables can be produced in large volumes. The electric Allrounder 470 E with a clamping force of 1,000 kN and a size 400 injection unit operates with a mould from Tim Plastik, Turkey, and produces the parts in a cycle time of eleven seconds per eight 20-ml syringe barrels made from PP. The part weight is 7.6 grams. To meet the high demands for component tolerances, complex temperature control is used. Before the mould opens, thread demoulding is performed by an unscrewing unit.
Cost-effective automation solutionThe third exhibit will demonstrate the performance of the proven Golden Edition hydraulic machine series. Using a single-cavity mould, an Allrounder 420 C Golden Edition produces a box out of PP. The cycle time is around 10 seconds. Removal of moulded parts is performed by a Multilift Select, the entry-level model of the linear Arburg robotic systems. It features servo-electric drive axes and is fully integrated into the Selogica machine control system. For the operator, this means: only one data record, no rethinking in programming and perfect synchronisation of robot and machine. Thanks to the teach-in function, the Multilift Select is also extremely easy to program. This approach has obvious advantages: programming times and changeover procedures are reduced effectively, the overall handling sequence is safer and training costs are much lower.
With a conveyor belt and guarding, the Multilift Select together with the Allrounder Golden Edition form a complete automated production unit that is immediately ready for production.
