Home Products Gravimetric dosing MCHybrid 30 MCHybrid 30: the best of dosing and blending in one system The MCHybrid 30* is a unique dosing concept that combines two technologies into one system: batch blending and in-line dosing. The main materials or regrinds are mixed in an extreme compact gravimetric batch blender. Because the system only blends the main materials, the blending speed is high and therefore the batch blender remains small. The additives are dosed gravimetrically in-line, directly on the throat of the injection molding machine or extruder. By using these two blending and dosing technologies in one machine, you are able to control the main materials in any given ratio and at the same time dose additives at low percentages with unequalled accuracy.
