BB Engineering will present itself as an expert in extrusion, mixing and filtration as well as an innovator in PET recycling at the forthcoming K plastics show in Düsseldorf, Germany, from October 19-26.

As a joint venture of Brückner Maschinenbau and Oerlikon Barmag, BB Engineering took over the extruder division of Oerlikon Barmag in 2002 and can thus draw on more than 60 years of experience in extruder construction.

To date, approximately 20,000 extruders have been delivered worldwide mainly used in film and synthetic fibre spinning lines for PP, PET, PA and PE. BB Engineering is the exclusive supplier to its parent companies and also sells extrusion and filtration technology to third party customers. The portfolio also includes various continuous and discontinuous polymer filters and polymer mixers.

“Our company has always stood for high-quality, durable machines and components that enable our customers to manufacture first-class products,” said MD Klaus Schäfer. “A high-quality melt is crucial for trouble-free production and good, consistent product properties.”

For a number of years, BB Engineering has been focusing its development work increasingly on recycling technologies. In addition to extruders, filters and mixers that are suitable for both recycling processes and the processing of recyclate, the company offers VacuFil  – a complete PET recycling plant.

It combines gentle large-scale filtration and targeted regulation for consistently outstanding rPET melt quality and processes a wide range of both post-production and post-consumer input materials.

The patented Visco+ vacuum filter removes volatile impurities quickly and reliably.

VacuFil is a modular system that can be designed for different recycling applications and there are no limits to the downstream processes. Simple granulation is possible, but also direct feeding into further processing, e.g. in the synthetic fibre spinning mill. BBE offers VacuFil in combination with its own VarioFil compact spinning plant to produce polyester yarn.

Open House

It is possible for this process to be observed during the K show at an open house at the company’s nearby site in Ramscheid, where BBE and Oerlikon Barmag will provide customers and interested parties with an overview of its technical centre. Here, visitors can experience the VacuFil Visco+ recycling technology in operation with a connected VarioFil spinning plant and observe for themselves how high-quality recycling yarn is produced from PET waste.
