Melt modification – 3DD mixer

Quality and output performance are not mutually exclusive.

The BBE mixer systems solve a whole range of mixing and metering tasks when processing plastics and within the chemical industry. It is the superb flexibility and quality of your systems that guarantee efficient production. Extremely high metering accuracy and mixing performance ensure that your products are top quality.

A range of feed and mixer systems are available to cater to the requirements of flexible production.



Why Melt Modification?

Polycondensation systems do not permit the inclusion of dyes or other additives during the polycondensation process. For this reason, only a limited product range can be manufactured (i.e. raw white); targeted changes to the melt properties are not possible.
3DD mixing systems enable the inclusion of dyes and other additives in granulate form at virtually any stage of the process. Also, including and mixing liquid additives is possible. Using 3DD technology enables the manufacture of a wide range of colors and modified yarns depending on the type of mixer. From the outset, 3DD technology offers superlative flexibility for new polycondensation systems. It can also be installed in existing systems to increase efficiency and flexibility.
In addition to plastic melts, other media used in the plastics industry can also be added for economically manufacturing PET fibers and films.
