    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

    Extruder screw characteristics

      Generally, the screw is divided into three sections, namely, a feeding section, a compression section, and a homogenization section. Feeding section - the bottom is small, the main function is to transport the raw material to the rear section, so it is mainly the conveying capacity problem, the pa... Read More
