Abstract: A stepped flight is formed on a screw of an injection molding machine. The stepped flight is a flight in which a step-shaped step portion is formed on a top portion thereof. The top portion of the flight includes a large diameter portion on an upstream side and a land portion on a downstream side. When a gap ratio m of a gap H1 between the land portion and a bore of the heating cylinder to a gap H2 between the large diameter portion and the bore is defined as H1/H2, the gap ratio m is selected to be 2.3≤m≤6.4.

Abstract: The interior of a heating cylinder (2) is divided into a first stage (5) and a second stage (7) due to the shape of a screw (3). A first compression zone in which a resin is compressed is formed in the first stage (5). A starvation zone (7a) in which an inert gas is injected and a second compression zone in which the resin is compressed are formed in the second stage (7). A barrier flight (13) that is obtained by combining a main flight (14) and a sub-flight (15) having a greater lead angle than the main flight is provided to a section of the screw (3), said section corresponding to the first compression zone. A multiple flight is provided to another section of the screw (3), said section corresponding to the second stage (7).

Abstract: In a reaction apparatus, a kiln part includes a supply port configured to receive a raw material supplied to one end side thereof, a discharge port configured to discharge a reaction product to another end side thereof, a cylindrical par extending along and rotatable around a central axis thereof, and a baffle plate provided so as to extend from an inner wall of the cylindrical part and pass through a central area of the cylindrical part including the central axis thereof. A driving part rotates the kiln part around the central axis. A heating part heats an outer peripheral part of the kiln part. The kiln part is configured so that a received predetermined raw material is conveyed to the discharge port along the central axis while being in contact with the baffle plate.
