Arburg with future trends in Sweden: Electric Allrounder and complex automation
New electric Allrounder 270 A / Production cell with integrated assembly steps
"Despite current curbs on capital expenditure, we expect a positive outcome at the trade fair. We are guardedly optimistic about the year 2009 in spite of the recession, and see potential particularly in the packaging and medical sectors," says Stefan Folkesson, Managing Director of RAFO AB and Arburg trading partner in Sweden, cautiously expressing expectations in the run-up to the Elmia Polymer. "Speed and precision are in demand in both these sectors. We will therefore be presenting the new electric Allrounder 270 A. Another future trend is automation and the integration of downstream production steps, enabling cost-efficient production, even in high-wage countries. We will present this with a production cell incorporating a hydraulic Allrounder 370 S," says Stefan Folkesson, explaining the company's objectives in presenting these exhibits.
Expansion of the electric Alldrive series
With the premiere of the two new Allrounder 270 A and 720 A machines at the Arburg Technology Days in March 2009, Arburg has extended its range of electric machines at both ends of the size spectrum. The Allrounder 270 A will make its European trade fair debut at the Elmia Polymer.
This exhibit has a distance between tie bars of 270 x 270 millimetres, a clamping force of 350 kN and a size 70 injection unit with a maximum shot weight of 21 g of PS. The machine will demonstrate the production of a thin-walled printed circuit board with a length of about 2.5 centimetres, featuring 20 precision holes arranged in pairs.
Modular system with six machine sizes
With these two new machine sizes, the Alldrive series now encompasses six sizes and a clamping force range from 350 to 3,200 kN. Principal characteristics of Allrounder A machines are their speed, precision and energy efficiency. The main axes, with servo-electric drive as standard, enable simultaneous movements and consequently short cycle times. Depending on requirements, the auxiliary axes can either be driven electrically like the main axes, or hydraulically by means of an integrated small-accumulator hydraulic system. A further advantage of these electric machines is their low energy consumption. Accordingly, all Alldrive machines bear the Arburg "e2" energy-efficiency label.
Fully automated encapsulation of inserts
The second exhibit is a complex production cell with an Allrounder 370 S with a clamping force of 600 kN and size 170 injection unit. This system will demonstrate not only the encapsulation of inserts, but also the integration of downstream assembly steps. The Allrounder operates with an Arburg Multilift V robotic system, which enters vertically into the mould and is fully integrated in the Selogica machine control system. A toy buggy made from PP will be produced, the metal axles of which are encapsulated in plastic. In this application, the complex gripper of the robotic system inserts the metal axles, removes the sprue and the individual components and subsequently assembles them to produce the finished toy car.
Flexible products and comprehensive expertise
With this exhibit, Arburg will demonstrate the flexibility of its machines and robotic systems as well as the expertise of its project department, which assumes the role of general contractor and designs, implements and commissions customer-specific systems.
Focus on the Swedish customers' requirements
Stefan Folkesson stresses the importance of the exhibited machines for Arburg's continued strategic focus on the Swedish plastics market: "Practical, intelligent solutions are always in demand, not just in times of economic crisis. Complex production cells with integrated production steps for the cost-efficient production of moulded parts are a very significant future trend. In addition, in the Swedish market we are seeing increased demand for energy-optimised, fast and precise machines. These requirements are particularly well satisfied by the electric Allrounders, as their modular design allows them be equipped to suit individual needs."
