Regrind dosing

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 MCTwin, MCHigh Output 2500R and MCHybrid 30R-series.

Dosing equipment for simultaneous dosing of masterbatch and regrind

The MCTwin dosing unit was especially developed for the processing of regrind and consists of two gravimetric MCBalance 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.

Dosing regrind for 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 MCHigh Output which comes in both volumetric as well as gravimetric execution and goes as far up as 1.000 kg/h. The MCHigh Output is a perfect unit to combine with the MCWeight (measuring main flow) and the MCBalance (dosing color, catalyst, or other additive).
