Arburg at Medtec Europe 2012

(PresseBox) (Lossburg, ) .
- Efficient injection moulding solution for highest clean room standards
- Allrounder as stainless steel version
- Short cycle times thanks to precise configuration

At the Medtec Europe 2012, which will be held in Stuttgart from 13 to 15 March 2012, Arburg will present an efficient injection moulding solution that meets the highest clean room requirements. An electric Allrounder 520 A will be on view on Stand 6511 in Hall 6, possessing a fully encapsulated stainless steel clamping unit that can be cleaned particularly quickly and effectively. The hot runner system, which operates with electrically powered needle shut-off nozzles, also ensures an extremely clean working environment. Sixteen so-called "collecting tubes" will be produced in a cycle of 5.8 seconds. Thanks to the short cycle time and the energy efficiency of the electrical drives, the exhibit is characterised by a high level of production efficiency.

For medical applications, Arburg offers clean room solutions tailored to specific requirements. The modular product range covers hydraulic, hybrid and electric Allrounder with a clamping force range from 125 to 5,000 kN, for which tailored equipment packages are available. Furthermore, a variety of clean room concepts can be implemented. These range from machines and complete production cells that can be docked to a clean room, through to Allrounders that operate entirely within a clean room.

Efficient clean room production

Arburg will present a solution of this kind at the Medtec Europe. The clean room from Ionstatex will only be suggested on the stand, so that the exhibit and the application can be observed close-up. Electric Allrounder 520 A has a clamping force of 1,500 kN and operates with a size 400 clamping unit. The mould is provided by Ernst Rittinghaus, a company which exclusively uses electrical Allrounders from the Alldrive series to manufacture its clean room products. The mould in question has 16 cavities and is used to produce dosage chambers for laboratory analyses. The so-called collecting tubes are made from medical-quality polypropylene, have a moulded part weight of 1.06 g and are produced in only 5.8 seconds.

The short cycle time and the energy efficiency of this application are a result of electric machine technology on the one hand, and the optimum configuration of machine, mould and temperature control on the other. The hot runner from Günther Heißkanaltechnik features needle shut-off nozzles that are electrically driven by a linear servo-motor. The advantages over pneumatic systems are evident in terms of precision, energy requirements and cleanliness, the decisive criteria when it comes to clean room production.

Unique stainless steel solution

The electric Allrounder 520 A meets the highest hygiene requirements in accordance with ISO 13485, as well as the specifications of the FDA and the GMP directives thanks to the encapsulated stainless steel clamping unit, which is unique to Arburg. The stainless steel surfaces can be cleaned much faster and are insensitive even to the aggressive agents commonly used during sterilisation. Moreover, the raised machine base, which is covered on the injection side, as well as the nickel-coated mounting platens with covered holes are advantageous in terms of cleaning. The resulting reduction in downtimes also brings greater efficiency in production.

A clean-room module with air ionisation above the machine's clamping unit ensures that the air in the work area is kept as free of particles as possible. The module generates a high level of air circulation via a pre-filter and HEPA filter, as well as neutralising electrically charged moulded parts. Liquid-cooled drives and control cabinets are standard at Arburg and also aid low-emission production.

Furthermore, only FDA/NSF H1-compliant lubricants are used.

Accordingly, the Allrounder presented at the Medtec Europe meets the clean room requirements of ISO classes 5 to 7.


Arburg, a German machine construction company, is one of the leading global manufacturers of injection moulding machines for plastics processing with clamping forces between 125 kN and 5,000 kN. Fields of application include the production of plastic parts for motor vehicles, communications and consumer electronics, medical technology, domestic appliances and packaging. The product range is completed by robotic systems, complex projects and other peripherals. Arburg's operations are coordinated by an integrated management system and are DIN EN ISO 9001 and 14001 certified. Arburg is represented by its own organisations at 32 locations in 24 countries and by trading partners in more than 50 countries. However, production takes place exclusively in the parent factory in Lossburg (Germany) - with the mark of quality "made by Arburg - made in Germany". From a total of around 2,150 Arburg employees, 1,800 work in Germany. A further 350 employees work in Arburg's organisations around the world.
