In the plastics industry, savings go hand in hand with a stable and sustainable production process. Movacolor asked its engineers to develop a dosing machine that can dose scrap and waste directly as regrind along with the masterbatch or free-flowing powder and correlate the volume of color directly to the volume of regrind. The engineers answered with the MCS Regrind, MDS HO Balance, and MBS Blender 3-series.

Dosing equipment for simultaneous dosing of masterbatch and regrind

The MCS Regrind dosing unit was specially developed for the processing of regrind and consists of two gravimetric MDS Balance units. Depending on the amount of regrind, Masterbatch is added accordingly. More regrind means less masterbatch, and more masterbatch means less regrind. In practice, this special, very accurate dosing system for regrind provides substantial savings of masterbatch and the sensible use of rejects and waste.

Regrind in combination with a high-performance extrusion line

In an extrusion process, regrind can be in flake form, irregular form or pellet form. It can be factory scrap or post-consumer scrap. In all forms, it is important that it is added into the process in such a way that it will not disturb the melting and/or gelation process in the screw. Therefore, the dosing volume must be constant and its amount should follow the volume of the main flow, also with high fluctuations in bulk density. For these cases, Movacolor has developed the MDS HO Balance, which comes in both volumetric as well as gravimetric execution and goes as far up as 1.000 kg/h. The MDS HO Balance Output is a perfect unit to combine with the MMS Weight (measuring main flow) and the MDS Balance (dosing color, catalyst, or other additive).
