Arburg: bringing history to life

The completely redesigned “Evolution” exhibit at the company’s headquarters in Lossburg (northern Black Forest) brings Arburg’s history to life. Covering around 770 square metres, the exhibition area offers visitors an interactive approach to the company’s history – from its founding in 1923 to the present.

Videos and so-called thematic and vision spheres are used in the new “Evolution” exhibition to present multimedia content about Arburg and historical events (Photo: Arburg).

The exhibition includes injection moulding machines the Freeformer for additive manufacturing and many more innovations, historic milestones and product examples from the last 90 years. Accounts of historical events and wide-ranging multimedia content complement the exhibition.

Many answers
How did Arburg become the worldwide leading manufacturer of injection moulding machines? Who are the heads of the family-owned company? Why was the first machine built from a bombed-out railway bridge? How has the brand developed over the decades? How will plastic materials be processed in 2040? – Customers will find answers to these and many more questions when they visit the modern “Evolution” exhibition at Arburg, which includes numerous exhibits and interactive touchscreen monitors.

From medical devices to the Freeformer
For example, visitors will see the first medical products made in 1923, consumer goods manufactured during the Second World War, flash units from the period of the Economic Miracle and, of course, the company’s milestones in injection moulding machine technology, right up to today’s Allrounder machines and the brand new Freeformer for additive manufacturing.

For everyone interested in injection moulding
The presentation is rounded off with an exhibit wall containing around 600 plastic parts, videos and so-called thematic and vision spheres. Visitors can call up detailed information on various levels, covering topics such as injection moulding processes, automation, corporate development, the brand, trade fairs and historical events, as well as taking a glimpse into the future.

Micro injection moulding machine

To coincide with the 27th International Colloquium Plastics Technology, the Institute of Plastics Processing (IKV) in Industry and the Skilled Crafts at RWTH Aachen University put a new electric Allrounder 270 A injection moulding machine from Arburg, Lossburg, into operation.  At the heart of this system is a micro injection moulding unit, the plasticising cylinder of which has been developed jointly by Arburg and the IKV.

The innovative plasticising unit, a so-called “inverse screw” is characterised by its special geometry. In distinction to conventional three-zone screws, the thread turns necessary for plasticising and melting the material are incorporated in the cylinder.

Micro injection moulding machine with new plasticising unit
The necessary relative movement is generated by means of an internal rotating piston. As the forces acting upon the piston are lower compared to plasticising screws, a significantly more compact plasticising system can be implemented, which is ideal for use in micro injection moulding. In addition to a reduced dwell time of the melt in the plasticising cylinder, the injection process can be controlled more effectively due to the smaller piston diameter. The mass fluctuations can thereby be reduced and the repeat accuracy of the injection cycle improved considerably. This has a positive effect on the achievable part quality.

Influence of geometry investigated and optimised
The effectiveness of the process has been evidenced through extensive joint studies carried out by Arburg and IKV. The influence of the geometry on the achievable feed rate and the melting characteristics in particular were investigated in order to progressively optimise the geometry. With the transfer of the geometry to a commercial injection moulding machine, use in a fully-automated injection cycle and consequently the potential of the technology in industrial application is now to be demonstrated.

Electric Allrounder produces precision parts

At the Swiss Plastics trade fair, which will take place from 21 to 23 January 2014, ARBURG (Hall 1, Stand C1061) will present a cost-effective injection moulding solution for technical precision parts.

 The company's spokeman says: "The versatility of our Allrounder injection moulding machines is matched by great variety of plastic products made with them. Whether you come from the medical, automotive, electronics, packaging or technical injection moulding industry, with Arburg you can be sure that you have the right partner at your side.

Peak performance! Winter sports equipment “Made with Arburg”. The company’s spokeman says: “The versatility of our Allrounder injection moulding machines is matched by great variety of plastic products made with them. Whether you come from the medical, automotive, electronics, packaging or technical injection moulding industry, with Arburg you can be sure that you have the right partner at your side.

Visitors to the Luzern show will be able to discover an electric Allrounder 370 E injection moulding machine with servo-electric Integralpicker

Cost-efficient entry into the world of electric machines
“All factors that increase energy efficiency, reduce cycle times and optimise production organisation help to improve the cost-efficiency of part production,” explains Marcel Spadini, ARBURG’s subsidiary manager in Switzerland. This is precisely what will be demonstrated by the exhibit, an electric Edrive series Allrounder with a servo-electric Integralpicker V. The machine will use a Stamm mould to produce two 8.5 g housings for knife sharpeners in a cycle time of 23 seconds. The robotic system offers low-cost entry into automated part removal.

Additive manufacturing with the freeformer
Furthermore, visitors to the Swiss Plastics fair in Lucerne will have an opportunity to see the new freeformer for themselves as part of a specialist presentation. This unique system for additive manufacturing will be introduced by one of its creators, Arburg Managing Director Technology & Engineering Herbert Kraibühler.
