machinery www.smart-molding.com Fast: Medical technology on hybrid Allrounder 470 H On a hybrid Allrounder 470 H with a clamping force of 1,000 kN, size 400 in - jection unit with 35millimetre standard screw and Gestica control system, pi - pette tips will be produced from PP in a 64-cavity mould. The cycle time for this high-speed product is only seven sec - onds, which is partly due to themachine being equipped with powerful mem - ory technology and the aXw Control ScrewPilot for reproducible injection and high moulded part quality. The shot weight is 64 grams. The complex automation comes from regional Chi - nese manufacturer Ningbo Welllih Robot Technology Co, LTD. In addition to a Luxor80 granule feed fromMotan, a hot runner system from Husky and two HB-Therm temperature control devices are also used. Safe: Face mask on Allrounder 570 E Golden Electric A face mask will be injection mould - ed in a 4-cavity mould from Polarform Werkzeugbau GmbH. The sample part will run on a 570 E Golden Electric Allrounder during Chinaplas. The high- end system with this machine for LSR processing is a novelty in Asia. The Allrounder 570 E Golden Electric is de - fined here as an entry-level machine with maximum precision for the spe - cial application of LSR injection mould - ing. It has a clamping force of 2,000 kN and a size 800 injection unit with a 45- millimetre LSR screw and no mixing or compression zone. A special non-return valve is also used for low-viscositymate - rial. AWacker Chemie AG LSR optimised for medical technology is processed. The moulded part weight is around 42 grams and the cycle time some 60 sec - onds. The extreme undercut of themask and different wall thicknesses with the very thin lip make the injection mould - ing of these parts highly complex. The gripper on the Multilift Select robotic system with a 15-kilogram load capac - ity in transverse design ensures precise, smooth removal. It comes from Barth Mechanik GmbH, and the dosing system from Chinese manufacturer Mucomac in Shenzhen. The system is completed by a CoolShot cold runner system from Ewikon with electrically needle-type shut-off system and a cooling unit from Shini in Taipei. For medical technology, which is also one of the most important industries in this region, clean produc - tion with maximum process control is indispensable. Arburg can fully guaran - tee this with this configuration. Large: Allrounder 820 S with equipment for FDC processing The largest Arburg machine at Chinaplas will be a hydraulic Allrounder 820 S optimised for fibre direct com - pounding (FDC). The machine has a clamping force of 4,000 kN and a size 3200 injection unit equipped with a 70-millimetre special screw for long glass fibre processing. The aXw Control ScrewPilot, which allows reproducible mould filling via the control of injec - tion pressure and speed is also includ - ed as necessary basic equipment. The single-cavity mould has a hot runner with needle-type shut-off nozzles. The moulded part weight is 700 grams and the cycle time some 80 seconds. FDC moulded parts are used in all in - novative sectors of plastics processing, such as automotive construction or the aerospace industry. Themoulded parts are removed from the singlemould via aMultilift Select ro - botic system with a load capacity of 15 kilograms. Downstream, the items are weighed inline via a scale automation system for quality assurance, entered into the process documentation, and then deposited on a conveyor belt. Business potential in China and Asia remains high According to Zhao Tong, the exhibits at Chinaplas 2022 are a perfect match for the current market requirements in China: "The automotive industry is becoming increasingly energised by developments and applications in the field of e-mobility. In medical technol - ogy, Arburg canmake an important con - tribution to more stable supply chains thanks to its central production, its on- time delivery, and the high reliability of its Allrounders. More and more compa - nies are also looking to IT solutions such as the arburgXworld customer portal and the ALS host computer system to in - crease their production efficiency. With our products and technologies that are 'Made in Germany', we are in the right place at the right time. Because – and this is also demonstrated by our involve - ment in Chinaplas – we can offer our customers regionalised services to fully support them in increasing quality, ef - ficiency and resource conservation in their companies."
