The problem that the barrel screw plasticization is not good should be noted: 1. Clean the rubber head or replace the rubber head! Remove the head and burn it with fire. Thoroughly clean the remaining material on the rubber head. 2. Check carefully, starting from the hopper, and the inner spring noz... Read More
Extruder screw parameters and influence First, several important geometric parameters of the 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 hi... Read More
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
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
The main factors affecting the quality of plasticization are: aspect ratio, compression ratio, back pressure, Screw speed, barrel heating temperature, etc. 1. Length to diameter ratio: the ratio of the effective working length of the screw to the diameter of the screw. a, the ratio of long diamete... Read More
