Plasticization device, injection molding apparatus, and three-dimensional modeling apparatus

Abstract

A plasticization device that plasticizes a material, includes: a drive motor; a rotor that is to be rotated by the drive motor and has a groove-forming surface in which a curved projection strip portion is formed from a peripheral edge of a circular central portion toward an outer periphery of the rotor; a barrel that faces the groove-forming surface and includes a communication hole at a position facing the central portion of the groove-forming surface; and a heating unit that heats the material supplied between the rotor and the barrel, the rotor includes a protrusion protruding from the central portion toward the communication hole, and 0.28≤S2/S1≤1.03  (1), wherein S1 is an area of the central portion and S2 is a maximum area of a cross section of the protrusion along the groove-forming surface.
