Different components for manufacturing compound materials will be the focus of the Oerlikon Barmag stand at this year’s JEC trade fair in Paris.

The machine and systems builder will be informing visitors about new products and services in pump construction and about winders for specialty yarns at the composites industry trade fair that will take place from 11-13 March.

High performance fibres

The majority of common high-performance carbon fibres are today manufactured from polyacrylonitrile. The most significant feature of these fibres is their high modulus with simultaneously very low weight.

This modern material is meanwhile being deployed in many sectors of industry; for instance, in medical technology, in the aerospace industry, the wind power and the automobile industry.

Manufacturing carbon fibres

With the WinTrax, Oerlikon Barmag has developed a winder especially for manufacturing carbon fibres. The winder, which has been designed both for one- and two-cop systems, is said to unite the economic production of carbon fibres of the very highest quality with a simultaneously perfect package build and identical running length.

Both low and high package weights of up to 20 kg can be manufactured. The higher package weights shorten the tooling times and therefore is said to considerably reduce the time and costs for manufacturing compound materials. As a result of the identical running length of all packages, waste is eliminated, the company reports.

Processing specialty yarns

Specialty yarns made from aramids are characterised by their extremely high tenacity, high elongation at break, excellent vibration absorption and resistance to acids and bases. They are also heat- and fire-resistant.

The yarns are not only deployed for special applications, they must also be processed in a very special way. The WinOro automatic precision winder is said to handle yarn gently. Its package build, energy efficiency and a high degree of cost effectiveness make it the perfect solution for demanding specialty yarns, according to the manufacturer.

Flexible production

Oerlikon Barmag will be reporting on its self-sufficient GM Control metering unit. With this, the company has responded to the demand from many users for an easy-to-operate plug-and-play version of its proven series of GM metering pumps. The unit can be directly controlled, but can also be retrofitted to existing process control units.

The core of the GM Control metering unit, the GM pump, is available for numerous different conveying capacities. For this reason, operators can now always choose the most suitable metering unit for the most diverse range of throughput volumes.
