摘要： The present invention provides an extruder configured to extrude a solid raw material containing moisture, the extruder comprising: a barrel having a hollow tubular shape in a longitudinal direction, wherein a hopper into which a raw material is put is coupled to one side of the barrel, and a discharge port through which a dehydrated raw material is discharged is provided on the other side of the barrel; a rod-shaped screw provided with screw threads on an outer circumferential surface thereof so that the screw is mounted within the barrel to transfer a raw material put into the hopper to the discharge port while axially rotating in one direction; a vent part disposed at one point between the hopper and the discharge port to discharge vapor generated within the barrel to the outside; and a heater part mounted on the barrel to heat the raw material. The raw material introduced into the barrel through the hopper is gradually heated by the heater part while being transferred within the barrel through the screw. A kneading zone, in which raw materials transferred by the screw threads are compressed, is formed on the screw. Since the raw material is melted within the barrel so that at least a portion of the raw material is phase-changed into a liquid state, a heating temperature of the heater part and an axial rotation speed of the screw are controlled so that a sealing membrane that shields an inner transverse section of the barrel is formed from the liquid raw material in the kneading zone.

摘要： A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread formed thereon, the thread having pushing and trailing surfaces. The body has an outer surface and extends longitudinally between feed and discharge ends. A channel for receiving the material to be processed is defined between the outer surface of the body and an outer diameter of the thread bounded by the pushing surface and the trailing surface of the thread. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end.

摘要： Provided is a method for manufacturing a foam molded body having high heat resistance. A method for manufacturing a foam molded body using a plasticizing cylinder having a plasticizing zone and a starvation zone comprises: plasticizing and melting a thermoplastic resin into a molten resin in the plasticizing zone; introducing a pressurized fluid containing a physical foaming agent at a constant pressure into the starvation zone to maintain the starvation zone at the constant pressure; bringing the molten resin into a starvation state in the starvation zone; causing the molten resin in the starvation state and the pressurized fluid containing the physical foaming agent at the constant pressure to come into contact with each other in the starvation zone with the starvation zone maintained at the constant pressure; and molding the molten resin that has been brought into contact with the pressurized fluid containing the physical foaming agent into a foam molded body. The thermoplastic resin is super engineering plastic, and the constant pressure is 0.5 MPa to 12 MPa.
