Dosing units

Our sophisticated and robust dosing units form the core our PLASTICOLOR system. They are available in four different sizes, each with an output ranging from 70 g/h to 4,800 kg/h.

Fields of application

These units are designed and used for the dosing of granular, free flowing and non-sticky materials, such as masterbatch, regrind materials, virgin materials and PVC dry blends. They cover all extrusion, blow-moulding and injection moulding manufacturing processes. Depending on the requirements, our dosing units can either be used individually or as a complete solution.

  • Filling or discharge during production (starting from two units) by means of neckpiece slides (manual or pneumatic)
