Injection screw can be divided into three sections: feeding section, compression section and homogenizing section. Generally, the ratio of the three segments of different plastics will be different.
Feeding section - the bottom diameter is small, which is mainly used to transport raw materials to the rear section, so it is mainly a problem of conveying capacity.
Compression section - bottom diameter change, mainly used to compact and melt materials and build pressure.
Homogenizing section (metering section) - extrude the melted materials in the compression section to the front end of the screw at a fixed amount and temperature.
The compression ratio of injection molding screw refers to the ratio of the volume of one screw groove in the feeding section of the screw to the volume of the last screw groove in the homogenizing section (metering section).Plastics Injection Molding Machines for sale
