  • Larger variety of products can be produced in a simple way 
  • Low waste while changing the product 
  • Small quantities of special products may be produced
  • Gravimetric
  • Gastight
  • Continuous
  • Microprocessor controlled

Accurate dosing for any masterbatch directly at the extruder inlet.
