PET preforms is an industry in which quality is essential. Localized change of color and ultra-low color percentages is one of the problems the PET preforms industries faces. And on top of this color has to be dosed in a main stream of dried main material of over 160°C.
This can be prevented by using a dosing unit which is extremely stable and accurate in combination with a special stainless steel neckpiece. Effective use of additives like masterbatch, powder and liquid colorants ensures producers of PET preforms the highest quality at the lowest cost.
There are several options available to producers of PET preforms for dosing masterbatch, powder, regrind and liquid colorants. One can choose between gravimetric or volumetric technology. Movacolor’s modular design allows PET preform producers to choose a custom-made dosing unit that perfectly fits their specific type of production. The dosing unit is also easy to adjust or upgrade.
