A significant improvement in the range and accuracy of results achievable in laboratory tests and development work is offered by the new Baker Perkins MPX19 twin-screw extruder.

 

Designed for use in powder coating, toner, EMC, plastics and pharmaceutical environments, the MPX19 is a bench-top machine with features that replicate Baker Perkins’ range of larger extruders and ensure reliable scale-up to production outputs.

 

Its uses include quality control, investigating process problems, developing new product lines or even designing complete new processes. The latter is particularly useful for companies wanting to move from batch to continuous production.

 

A new control system – with identical functionality to production machines – includes a full formulation management system holding up to 50 formulations; historical trending of data, and connectivity to a PC or network to capture that data. Automatic start up and shut down sequences reduce the time required to set up and clean down for each run.

 

The MPX19 features the clam-shell barrel and segmented screw assemblies found on all Baker Perkins industrial extruders. These allow different screw configurations, process settings and formulations to be tested and quickly assessed by stopping the machine and opening the barrel to see the state of material being processed. Adjusting and testing the formulation, process settings and screw configurations are all straightforward.

 

Available as a fully integrated package with on-board HMI or a stand-alone unit with a separate panel, the MPX19 provides outputs in the 5 to 25 kg/hour range. Segmented screws allow great flexibility for profile design, and splined agitator shafts maximise reliability.

 

An electrically heated / water cooled barrel gives tight temperature control; a chill roll is included; and barrel lengths can vary from 15:1 to 40:1 L/D, with multiple process zones for a variety of applications.
