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
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
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
Injection molding machine barrel screw design principle: The main part of the pin screw is a conventional screw which can be placed in the groove of the melting section or the metering section of the screw or the smooth cylindrical surface without the groove at the end of the metering section. The p... Read More
