Innovative machine and application technology at the Scandinavian Open 2007

Around 290 trade visitors at Arburg under the motto of "Clean-room and high-speed applications”

(PresseBox) (Lossburg, ) Danish subsidiary Arburg A/S and the trading partners in Norway and Sweden invited their customers to Copenhagen for the fourth Scandinavian Open from 31 May to 2 June 2007. Around 290 trade visitors travelled to the Scandinavian in-house exhibition, whose motto this year was “Clean-room and high-speed applications”. Six Allrounders with clamping forces of 125 to 3000 kN were presented. Highlights of the three exhibition days were the electric Alldrive machine series and a medical application under clean-room conditions on an Allrounder 270 U.

In addition, a vertical machine, a special automation solution, the largest Allrounder Golden Edition and also another machine from this successful series were exhibited. Again this year, four specialist presentations including the main topic of the in-house exhibition, rounded off the successful event of Arburg’s Danish subsidiary.

Generous exhibition space

The success of the Scandinavian in-house exhibition continued this year with an exhibition space of over 650 square metres. Around 290 trade visitors from Denmark, Norway and Sweden came to the exhibition venue in Hvidovre, in the direct vicinity of Arburg's Danish subsidiary. The Danish subsidiary was again responsible for organising the three-day event this year. The Arburg trading partners in Norway and Sweden lent their support to the subsidiary’s manager, Eddie Oswald, and his Danish team.

Medical application in the clean-room

Commensurate with the exhibition motto, a medical application on an Allrounder 270 U and a thin-walled high-speed application on an electric Allrounder 420 A stood in the foreground. The Allrounder 270 U 350-70, which was exhibited in Copenhagen, has an internal distance between tie bars of 270 mm, a clamping force of 350 kN and a size 70 injection unit. The Allrounder, equipped with an eight-cavity mould, produced a stopcock valve made from ABS in a cycle time of nine seconds. The project system operated with a Multilift H. Both the clamping unit of the machine and the operating area of the Multilift were equipped with separate clean air modules, including air ionisation, which ensured a clean atmosphere during the entire production and removal cycle. The stopcock valves were produced on an 8-cavity mould made by Carmo, removed by the Multilift and set down on a conveyor belt with a surrounding tunnel cover. This conveyor section, which is also fully encapsulated, transported the parts to a modular, decentralised clean-room from Alpha Ionstatex, where the parts were further processed.

High-speed application on an electric machine

Polypropylene cups were produced with a two-cavity mould in a cycle time of 2.2 seconds on an Allrounder 420 A 1000-400 with a distance between tie bars of 420 millimetres, a clamping force of 1,000 kN and a size 400 injection unit. In addition to a pneumatically-operated needle shut-off nozzle for sprue-free injection, the machine also features an electro-mechanical ejector for rapid demoulding. With this equipment, the Allrounder A is ideally suited to high-precision but also rapid and reproducible production cycles with thin-walled parts. The high output levels also have the advantage of reducing unit costs, resulting in a short, economically advantageous payback period for the initial investment.

Automation solution

At the in-house exhibition, an Allrounder 270 U 350-70 encapsulated a special INOX blade with dyed ABS in a cycle time of 22 seconds. Mould conditioning was performed via a temperature control unit. Optimum material preparation and transportation were ensured by a Thermolift 100-2 integrated in the machine peripherals. A workpiece carrier/changer comprising a change unit and an insertion system, made by IfK Automation was connected to the Allrounder, which featured a vertical clamping unit. Two workpiece carriers were fastened to the rotary table of the changer opposite one another, and alternately fed with the pre-moulded part and the special stainless-steel blade.

Additional exhibits and specialist presentations

In addition, two sizes of the Allrounder Golden Edition machine series were on display in Copenhagen, the 720 S and the 470 C Golden Edition. Manual insertion and removal was demonstrated with the production of a contact insert on the small vertical Allrounder 175 V machine. Thanks to optimum conception, the hydraulic Allrounder V vertical machines are ideally suited to integration in production lines. Four specialist presentations rounded off the comprehensive technology programme at the Scandinavian Open 2007. Commensurate with the event's motto "Clean-room and high-speed applications", the presentations “High-speed production with Allrounder A" from Arburg and "Clean-room technology for plastics moulding" from Alpha Ionstatex stood in the foreground.
