Section Description Of Extruder Screw Barrel

Extruder screw barrel can be divided into feeding section, compression section, homogenization section (also known as metering section). (Note: the ratio of the three sections of different screws is not the same, the depth of the screw groove is not the same, the transition form of the bottom diameter of the screw is not the same).

1, Feeding section description: this section of the groove depth is fixed, its function is responsible for preheating and plastic solid transport and push. It must be ensured that the plastic begins to melt at the end of the feed section.

2, Compression section description: this section is the taper screw groove tooth depth, its function for plastic raw material melting, mixing, shear compression and pressure exhaust. At this point, the plastic will completely dissolve and shrink in volume, so the design of the compression ratio is very important.

3, Homogenization section description: this section is the screw groove fixed groove depth, its main function for mixing, melt glue transportation, measurement, but also must provide enough pressure, maintain the uniform temperature of melt glue and stable flow of molten plastic.
