"For more than 25 years, we have been providing plastics processors in Poland with high-performance machine technology and excellent service, and have established ourselves as a reliable and competent partner in the market," said Dr Sławomir Śniady, Managing Director of Arburg Polska Sp. z o o. "As our customers are increasingly interested in efficient electric machines and automation, this year we will showcase an Allrounder Golden Electric equipped with a linear Multilift robotic system. A hydraulic two-component Allrounder that processes liquid silicone and thermoplastic will demonstrate the versatility and flexibility of our modular injection moulding machines."
Sophisticated: two-component applicationAs a trade fair application, a hydraulic two-component Allrounder 570 S with a clamping force of 2,200 kN will produce ice scrapers in a hard-soft combination. The pre-moulded piece is first manufactured from PA using a horizontally arranged size 400 injection unit. A servo-electric index unit turns the 1 + 1-cavity mould from Polarform by 180 degrees. In this position, the liquid silicone (LSR) sealing lip is injection-moulded by the size 170 vertical injection unit via the needle-type shut-off nozzle. This dispenses with the need for automation. An LSR dosing insert from 2KM is used. The cycle time is around 60 seconds and the moulded part weight is 62 grams.
Electric: efficient injection moulding productionUsing the example of an optical application, Arburg will demonstrate the enormous potential of the electric Golden Electric series for the cost-efficient automated production of plastic parts at the Plastpol 2018. An Allrounder 570 E Golden Electric with a clamping force of 2,000 kN and size 800 injection unit will produce a magnifying glass weighing 22 grams from PC in a cycle time of around 45 seconds.
Dynamic mould temperature control ensures the quality of the optical component. The cavity is first heated during injection and cooled after filling. A linear Multilift Select robotic system removes the moulded parts from the mould and sets them down onto a conveyor belt.
