Important parameters of the homogenizing section screw

According to the theory of melt conveying, the flow of melt in the screw homogenization section has four forms, and the flow of molten material in the screw groove is a combination of these four flows: Positive flow-the flow of the plastic melt between the barrel and the screw along the direction of the screw groove towards the head.

Main parameters of screw in melting section

Compression ratio ε : Generally refers to the geometric compression ratio, which is the ratio of the volume of the first screw groove in the feeding section to the volume of the last screw groove in the homogenizing section. Epsilon = (Ds - H1) H1 / (Ds - H3) material H1 / H3

Main parameters of screw in feeding section

The helical elevation Angle ψ is usually 17° ~ 20°. The groove depth H1 is calculated by the geometric compression ratio ε of the screw after determining the groove depth in the homogenization section.

Segment of screw

When the material moves forward along the screw, it experiences changes in temperature, pressure, viscosity and so on. This change is not the same in the whole length of the screw. According to the changing characteristics of the material, the screw can be divided into adding (sending) material section, compression section and homogenizing section.
