挤出机的整机单耗则随着转速的增加而降低，随着压力、进料口温度、塑化段温度增加而上升。

Unit energy consumption of the extruder decreases as the speed increases, but raises with the pressure, inlet temperature, plastics segment increased.

在螺杆的设计不变的情况下，螺杆直径越大，计量段的槽深便越深，增加了塑化能力。

Everything else unchanged, the bigger the screw diameter, the bigger is the depth of the screw flight in the metering section, which increases plasticizing capacity.
