DESCRIPTION This unique device has been developed for PET preform pro-duction and for dosing materials with a low melting point (<40 °C). Flakes, masterbatch and virgin material are opti-mally dosed, mixed and fed to the processing machine. Virgin material flows freely out of the dryer and into the dosing device. Grinded material and additives (pigment) are added on a per-shot basis, the speed of the dosing worms and drums automatically synchronising with the injection moulding machine’s feed time. A special dosing worm developed for bottle flakes works the grinded material into the virgin material and blends the two with the aid of a stuffing unit. Depending on grain size, grain shape and flow behaviour, up to 80% flakes can be processed directly on the injection moulding machine with this arrangement. With precision drum dosing devices, the additive is added to the blend directly via a cooling tube. As well as colour batch, microbatch (PET-based) or Holco-batch (wax-based) can be added.

The integrated feed controller conveys virgin and grinded material to the dryer and draws material into the dosing stations.

WDx controlThe integrated conveying & dosing controller optimally conveys the desired material and ensures the high-precision dosing of up to 4 components.

The colour touch display ensures fast familiarisation thanks to its intuitive interface. Due to this the production process can be started in the shortest time possible. From administrator to operator without modification rights, different access rights can be assigned and controlled. This ensures correct and re-liable control.

Benefits• Dosing of up to 4 components• Intuitive operation with touch panel• User and access rights management• Log can be exported to USB stick• Recipe memory• Meter• External control module for conveying (optional)• Modbus UDP interface• FTP server• Installation of the controller directly on the production machine
