Swiss Plastics: successful start to exhibition year 2010 for Arburg
High-precision optical application impresses trade visitors / Optical waveguide with microstructures on electric Allrounder 270 A
The complex production cell consisted of an electric Allrounder 270 A (Alldrive), a horizontallyoperating Multilift H robotic system, integrated quality monitoring and peripherals. Highprecision optical waveguides with surface microstructures were produced. Optical components of this type find application in lighting or optical waveguide technology, for example. "This optical application with final quality control using a camera system proved to be a very special attraction", said Marcel Spadini, Arburg's Swiss Subsidiary Manager, regarding the interest of the stand visitors.
No less attention was given to the centrepiece of the automation solution, the electric Allrounder 270 A with a clamping force of 350 kN and a size 70 injection unit. "Many trade visitors were impressed by the performance potential of our smallest electric injection moulding machine", explained Marcel Spadini. "Above all, the high process reliability and the very quiet operation impressed. With the electric Allrounders, all of which bear the Arburg "e²" energyefficiency label, we have a machine series which is equal to the highest production requirements with regard to precision, reproducibility and energyefficiency. As the production of highquality, technical components is gaining increasing importance, with this complex production cell, we have selected exactly the right exhibit for the requirements of the Swiss plastics market."
Automated production and quality inspection
All parts handling tasks were managed by a horizontallyoperating Arburg Multilift H robotic system. Following removal of the moulded parts from the Advaltech AWM mould, the parts were transferred to a camera monitoring station, where they were illuminated from the side by four LEDs. This illumination with a light source is crucial in order to check the quality and function of the optical waveguide. Logos on the moulded part were made visible during this process. As a special quality feature, the camera checked the brightness of the parts to ensure the most uniform replication possible. Finally, the moulded parts were set down on a conveyor belt in a defined arrangement.
The PC granulate was prepared using an Arburg Thermolift material dryer and conveyor featuring a dry air unit. A temperature control unit with an interface to the machine ensured a precise mould temperature, which is absolutely essential in the production of optical components, in order to prevent striation and other flaws. All functions of the peripherals were integrated in the central Selogica control system, so that the entire complex production process, including quality checks, could be handled easily and reliably.
Positive trade fair outcome
"Our successful trade fair presence in Lucerne represents a great start for us in 2010", said the Swiss Subsidiary Manager. "Arburg has once again proven that meeting the most exacting demands in the field of individually customised automation solutions belongs to its core competences. Arburg's modular component system represents the ideal basis for efficiently implementing customer and sectorspecific injection moulding solutions." With regard to the Swiss plastics market, he added that, "The incoming order situation seems to be gradually recovering from the effects of the economic crisis, and is stabilising significantly. Markets such as the automotive and supplier industries are increasingly predicting an economic recovery. Heartened by the positive outcome of our trade fair presence, we are moving optimistically into the new decade."
