By extruding and pushing the unequal distance non-standard screw system of the feed expander, the gas in the material is discharged and quickly filled by the material. The material is subjected to shearing force and produces reflux, which increases the pressure in the machine bore. As the friction between the pile spinning and the chamber makes the material fully mixed, extruded, heated, glued and gelatinized, the original structure is damaged. Meanwhile, the mechanical energy is converted into heat energy through the friction of the material in the chamber, making the material into a liquid gelling state. When the material is extruded to the outlet, the pressure changes from high pressure to normal pressure and from high temperature to normal temperature.
