At the Plastics & Rubber Vietnam, which takes place in Ho Chi Minh City from 1 to 3 March 2016, Arburg will present an efficient production solution based on a hybrid Allrounder from the high-performance Hidrive series, thus placing the focus on the packaging industry. The high-speed Allrounder 570 H in the “Packaging” version will demonstrate the cost-effective production of drinks bottle closures.
“With a hybrid Allrounder 570 H in the “Packaging” version, we will be presenting an injection moulding application designed for high volume production in the packaging industry at the Plastics & Rubber Vietnam 2016. This efficient high-speed machine produces 24 water bottle closures in only three seconds,” explains David Chan, Managing Director of Arburg Singapore and responsible for the entire ASEAN region.
Packaging technology: Allrounder “Packaging”
In the packaging industry, fast, high-quality volume production using reliable and efficient technology is required. Specially for the production of screw caps, Arburg will present a hybrid Allrounder 570 H in the “Packaging” version at the exhibition. Its high performance capabilities will be impressively demonstrated, using the example of size 29/25 standard drink bottle caps for still mineral water. The exhibit, which features a clamping force of 1,800 kN and a size 800 injection unit, operates with a 24 cavity mould from Z-moulds. The high-quality screw caps weighing 1.25 grams are produced in a cycle time of around three seconds.
“Packaging” version: high performance and fast
Arburg offers a “Packaging” (P) version of the high-performance hybrid and electric Hidrive and Alldrive machines. These efficient high-speed machines offer high productivity and reduced energy requirements for applications in the beverage industry and are characterised by a well-balanced combination of distance between tie-bars, clamping force and opening stroke. Moreover, it provides fast, precise, energy-saving mould movements through servo-electric toggle-type clamping units, high plasticising flow rate through barrier screws and servo-electric dosage drives, dynamic position-regulated screws and effective injection flows volumes.
Special features for screw cap production
In addition to the basic equipment in the “Packaging” version, special features are available that enable the machines to be adapted to particular applications for the production of thin-walled items and screw caps. Fast, reliable ejection of mass-produced parts is what counts in screw cap production. A servo-electric ejector with a hydraulic boost function, i.e. an increased ejector force of 250 kN, is available for this purpose. This ensures problem-free demoulding, even in the case of shrunk-on closures. The “eject” and “open mould” steps can be synchronised. The dropping of the moulded parts can be precisely adjusted to keep the mould open times short. Higher screw circumferential speeds enable correspondingly short dosing times. This enables very short cycle times to be achieved.
