BB Engineering at the K show 2022

BB Engineering at the K show…

As a sub-exhibitor of Oerlikon, BB Engineering will present itself as an expert in extrusion, mixing and filtration as well as an inno-vator for PET recycling with the VacuFil and VarioFil R+ systems at the K.

Plastics competence - extruders, mixers, filters

BB Engineering is no newcomer to the plastics industry. As a joint venture of Brückner Maschinenbau (leading with film extru-sion lines) and Oerlikon Barmag (leading with man-made fiber spinning lines), BB Engineering took over the extruder division of Oerlikon Barmag already in 2002. BB Engineering can thus draw on more than 60 years of experience in extruder construction and is constantly engaged in development work to further opti-mize its products. To date, approx. 20,000 extruders have been delivered worldwide. The extruders are mainly used in film and synthetic fiber spinning lines for PP, PET, PA and PE. BB Engi-neering is the exclusive supplier for its parent companies and al-so sells extrusion and filtration technology to third party custom-ers. The portfolio also includes various continuous and discon-tinuous polymer filters from small to large (0.1-40m² filter area) as well as various polymer mixers.

The quality of the melt and thus of the end product is BB Engi-neering's top priority for all components and equipment. "Our company has always stood for high-quality, durable machines and components that enable our customers to manufacture first-class products. A high-quality melt is crucial for trouble-free production and good, consistent product properties" underlines Dr. Klaus Schäfer, Managing Director.


Recycling technology

BB Engineering has been focusing its development work increas-ingly on recycling technologies for several years. In addition to extruders, filters and mixers that are suitable for both recycling processes and the processing of recyclate, BB Engineering of-fers a complete PET recycling plant called VacuFil.

With VacuFil, BB Engineering has developed an innovative and unique PET LSP recycling process. And here, too, the focus is on product quality. The process combines gentle large-scale filtra-tion and targeted IV regulation for consistently outstanding rPET melt quality. Thus, much more than simple "downcycling" is pos-sible with VacuFil. VacuFil processes a wide range of input mate-rials - post-production and post-consumer. The patented key component Visco+ vacuum filter removes volatile impurities quickly and reliably. VacuFil is a modular system that can be de-signed for different recycling applications. There are no limits to the downstream processes. Simple granulation is possible, but also direct feeding into further processing, e.g. in the synthetic fiber spinning mill. BBE offers VacuFil in combination with its own VarioFil compact spinning plant to produce polyester yarn.


Open House

Exactly this process can be visited during the K show at an open house of BB Engineering and Oerlikon Barmag. Not far from Düs-seldorf, at the company's site in Remscheid, BBE and Oerlikon Barmag will open their doors and give customers and interested parties an insight into the technical center. Here, visitors can ex-perience the VacuFil Visco+ recycling technology in operation with a connected VarioFil spinning plant and see live how high-quality recycling yarn is produced from PET waste.
