The logic: coarse dosing systems run above the recipe with a safety margin in order to hold the color; weighed (gravimetric) dosing removes that margin. GRAVIMIX doses to an accuracy of 0.1%.
These calculations produce guide values; the final selection has to be based on the part geometry, the mold design and the data from the material manufacturer. For an assessment specific to your application, contact our technical support team.
Coarse dosing systems are run above the recipe in order to keep the color safe — on a volumetric unit this safety margin typically reaches 45% of the ratio. Because gravimetric dosing weighs every shot, the margin disappears.
The calculation compares the annual material cost of three systems that produce the same color result. The wider the price gap between the masterbatch and the base material, the shorter the payback period.
