PBS Lab Extruder Mark 1

The concept

The PBS Lab extruder MK1 is based on the standard tabletop extruder 30/600. This extruder is combined with a melt pump and controlled by a “Flow-Connect” controller by flowlink BV.

The package is fitted on a height adjustable frame, with an aditional horizontal lift to aid in changeovers, cleaning and maintenance operations. The whole package weighs <150 kg with a compact and mobile design.

Melt pump benefits

In this concept, the extruder functions as a feed pump to the melt pump, where the extruder serves the following functions:

  • Melting and mixing the polymer
  • Feeding the melt pump with a constant pressure and temperature

The melt pump in turn offers the ability to accurately control the troughput and allows the extruder to reach higher pressures at the output up to 350 bar. Besides that, the melt pump has the folowing benefits in processing:

  • Reduction of pultation
  • Reduced melt swirl
THe frame

The horizontal adjustment allows for flexibility in fitting auxiliary equipment between the extruder and pump like:

  • Static mixers
  • Breaker plates / filters
  • Valves
  • Measuring equipment

The machine can also be fitted with vertical height adjustment to adjust the nozzle heigth within a specific range.
