    摘要: A molding system having a melt pathway configured to convey a molding material. The molding system includes a viscous-drag sensor having: (i) a pathway blockage, and (ii) an actuator. The viscous-drag sensor is interactable with the molding material. The pathway blockage is movable along the melt pathway. The pathway blockage is movable along a first direction to further open the melt pathway. The pathway blockage is movable along a second direction to further close the melt pathway. The actuator is coupled with the pathway blockage. The actuator biases the pathway blockage to vary the melt pathway while the molding material drags along and moves the pathway blockage. Responsive to the pathway blockage sensing viscous-drag force, the pathway blocks acts to: (i) further open the melt pathway if a viscosity of the molding material is high, and (ii) further close the melt pathway if the viscosity of the molding material is low.
