    Several important geometric parameters of the extruder screw

    1, screw diameter (D) a, related to the required injection volume: Injection volume = 1/4 * π * D2 * S (injection stroke) * 0.85; b, in general, the screw diameter D is inversely proportional to the highest injection pressure, and is proportional to the plasticizing ability. 2. Conveying section a, ... Read More
