All components are blended by weight based on the setting shown on the master controller. Each component is dispensed separately into a single weighing chamber, and then all components are dropped into a continuous mixing chamber which delivers a homogenous blend.

The entire unit is designed to mount over the feed throat of the process machine. Maguire's unique weighing method allows blenders to operate correctly in spite of vibration or shaking caused by the molding machine or extruder.
