The exhibit, an ALLROUNDER 1600 T, features a rotary table with a diameter of 1,600 millimetres and 2,000 kN of clamping force. The product, a complex fluid distributor, contains different metal inserts, which are overmoulded with 35 per cent glass-fibre reinforced PBT. A 4-cavity mould from Concraft produces four finished parts in a cycle time of around 60 seconds. The shot weight is 74.5 grams.
The automation system provides three different types of inserts in a tray via a three-axis micro-robot. Then a six-axis robot with Concraft grippers and a load of 10 kg picks up a total of twelve inserts from this tray, and places them in the four cavities of the mould. After each injection process, it removes both the sprue and the finished parts. The turnkey system has been customised with a stamping unit with stamping line conveyor system, also from local partner Concraft. There, the inserts are first stamped out and have the pins separated, before they are placed in the mould and overmoulded. Implementation of the Kuka six-axis robot and the total system sequence was handled in the ARBURG Technology Factory (ATF) in Pinghu.
The electric drive together with precision position system ensures the high accuracy of the system and thus reliably protects the mould against damage and wear. Simultaneous insertion, overmoulding and removal ensure short cycles. The large selection of options for a flexible configuration is as advantageous as the high safety standard, which is above the CE standard. Particularly in challenging areas like medicine or mobility, the ALLROUNDER T provides precise results – also thanks to the pressure accumulator and lots of smart features on the SELOGICA control system that simplify setup and operation of the systems.
