Abstract

PURPOSE:To provide conical multi-shaft extruder screw to be used for plastic formation, rotating in different directions as engaging with each other by deepening depth of groove at base but not extremely shallowing its depth at the tip in order to protect overpressure. CONSTITUTION:Groove depth h2 of base is deepened and groove depth h1 of the end is settled in not extremely shallow depth in relation of position h2=h1XC2/C1 (0.6-0.75). Here, C1 is distance between center of axis of the end and C2 is the distance between center of axis of the base. Thus, the outer diameter of the screw is automatically determined so that defect of over-pressure as conventional is removed.
