Filling and dosing

For filling and dosing of the different raw materials (Virgin, Regrind, Masterbatch, Colours etc) into the extruder MEAF can supply multiple solutions according to the individual requirements of the customer. They are generally divided into the following 3 categories:

Gravimetric solution
The best and accurate solution is where the materials are mixed in a blender and are dosed by weight instead of volume. So independently from any influences such as temperature, humidity etc, the mix will always be according to the entered recipe assuring a perfect mix quality and saving expensive masterbatches.




  • Dosing is done automatically and extremely accurate
  • Recipes can be stored easily into the controlpanel of the blender

Volumetric solution
With this solution the materials are mixed in a dosage unit which doses the material according to the space it occupies i.e. it's volume.

  • Dosing is done automatically
  • Recalibrating is necessary when materials or circumstance change

The most simple way of filling and manually dosing is with a mixer. The raw materials are being filled into a seperate mixer manually and from there on the mixed materials are being transported to the extruder.







  • Simple and straightforward
  • Dosing is done manually
