The MCWeight is specially designed to measure the actual feed capacity of an extruder. It has an integrated weighing module to accurately measure throughput and an integrated knife valve to control the filling. Combined with one or more Movacolor units, the MCWeight tracks even the smallest capacity variation of the extruder. It adjusts the additive dosing from the dosing units accordingly. Dried material with a temperature up to 180°C can be handled with the MCWeight.
