Materials of the Future : Innovations from Oerlikon of Switzerland

If the Eiffel tower had been built 124 years later, Oerlikon would have assuredly played a significant part in its construction. Because what was riveted, screwed or welded together using iron and steel components back then would today be primarily made of composites – and the Oerlikon Textile, Vacuum and Coating segments today supply a wide range of technology and components for their production. These are the focus areas of research at the Oerlikon.

Carbon fibres are used in applications where low weight and extreme stability are prerequisites. Carbon fibre-reinforced plastics are used, to name a few areas, in the aeronautics and aerospace industry, wind power plants, automotive industry, safety technology and in high-quality sports equipment such as racing bicycles, tennis racquets, skis and boats.

2013-06-03_183245Oerlikon Barmag has developed a winder specially for the production of carbon fibres called WinTrax. The two-yarn winding head combines the economic production of top quality carbon fibres with simultaneously perfect package building and identical running lengths. In addition, the new WinTrax-A 2cop produces packages with a diameter of up to 310 mm. The resulting higher package weights reduce tooling times and therefore significantly reduce outlay during composite production. Due to the identical running lengths of all packages, waste is reduced to nearly zero percent.

2013-06-03_183607The production of composites frequently requires filaments or tapes with particular properties, such as high tensile strength, low elongation or a high modulus of elasticity. The extrusion systems for producing these high-quality tapes, mono-filaments and multi-filaments are other specialities of Oerlikon Barmag.

Another product worth mentioning here is the independent metering unit GM Control, newly developed by Oerlikon Barmag. Oerlikon Barmag is responding here to the demands of numerous users for an easy to use plug-and-play version of its proven GM metering pump series. The unit can be controlled directly and can also be retrofitted to existing process control systems.

2013-06-03_184251Whether for casting PUR parts, lamination of composite parts, metering additives in an ongoing extrusion process, application of cold adhesives or for flexible use in production systems with changing requirements – the compact and mobile GM Control unit can support all these tasks with the usual high metering accuracy and with even more ease of use.

The core of the GM Control metering unit – the GM pump – is available for numerous conveying capacities. This means that an appropriate metering unit can be provided for various throughput volumes.
