Arburg to highlight two Allrounder machine ranges at Chinaplas 2011

"The high-tech products from Arburg are predestined for the high-end sector, which is small, but increasingly important in the Chinese injection moulding market,” explains Zhao Tong, Arburg Subsidiary Manager in Shanghai. "What counts in this market segment is the quality of the machines with regard to precision and reproducibility. Moreover, the availability and service life of the injection moulding machines are important arguments in favour of our Allrounders,” adds Max Man, who is responsible for the trade fair in Guangzhou as Manager of the Arburg subsidiary in Shenzhen. In order to demonstrate the breadth of its machine range, the company will show two different series at the Chinaplas.  Hidrive: high-performance hybrid machines
The Allrounder 720 H with a clamping force of 3,200 kN, a size 2100 injection unit and a distance of 720 x 720 mm between tie bars, is one of the company's large hybrid machines. The Hidrive series currently comprises six machine sizes as well as a clamping force range from 600 - 5,000 kN. According to the company, the achievable production capacity of the Allrounder H is the result of combining well-proven servo-electric and hydraulic components from the modular Allrounder system. The servo-electric clamping units originate from the electric Allrounder A machine series and are complemented by hydraulic injection units from the Allrounder S with electro-mechanical dosage drive and position-regulated screw. Performance-adapted hydraulic accumulator technology completes the package. The Allrounder H machine concept has been designed for a high production capacity: Thanks to the hydraulic accumulator technology and the generously-sized injection units, Allrounder H machines also boast a correspondingly high injection performance in relation to the clamping force. According to Arburg, with the Allrounder H machines, the independent movement axes ensure a considerable reduction in cycle times. The high-precision, cost-effective toggle-type clamping unit can also be used to tap potential for reduced cycle times on the clamping side thanks to short dry cycle times, high acceleration and final speeds, as well as simultaneous movements of the clamping unit and ejector. With regard to the injection unit, the combination of position-regulated screw, hydraulic accumulator technology and servo-electric drives for mould and dosage also contribute to cycle time reductions, says the company. Thanks to the efficiency of the toggle-type clamping unit and servo-electric dosage drive, the Allrounders provide for energy-efficient operation. In addition, the energy recovery of the servo motors during braking also has a beneficial effect on the energy consumption of the machines. As well as the servo-electric drives and braking energy recovery, Allrounder H machines also use performance-adapted hydraulic accumulator technology with the minimum amount of installed pump capacity and motors of efficiency class EFF1. As a result and depending on the application, the energy-saving potential of the Hidrive machines can be as much as 40 %, says the company.  Golden Edition: entry-level hydraulic model
The second exhibit, the Allrounder 470 C Golden Edition with a clamping force of 1,500 kN belongs to the company's entry-level hydraulic machine series. These machines feature fixed clamping force/injection unit combinations and offer the company's usual high-quality technical components at a unique price/performance ratio. Like all Arburg machines, the Allrounder Golden Edition models are exclusively produced at the Lossburg parent factory.
