摘要

PROBLEM TO BE SOLVED: To secure wear resistance and ease of cutting in a thermoplastic device. A plasticizing device houses a drive motor, a rotor that is rotated by the drive motor and has a groove-forming surface, a barrel that faces the groove-forming surface and has a communication hole, and a rotor. A case, a heating portion for heating the material, and a wear suppressing portion provided between the rotor and the barrel and between the rotor and the case are provided. When a wear suppressor is provided between the rotor and the barrel, the wear suppressor is fixed to the rotor or barrel, and the Vickers hardness is higher than the Vickers hardness of one of the rotor and the barrel to which the wear suppressor is fixed. When a wear suppressing part is provided between the rotor and the case, the wear suppressing part is fixed to the rotor or the case, and the wear suppressing part of the rotor and the case is fixed to one Vickers hardness test. It has a higher Vickers hardness than the above. [Selection diagram] Fig. 2
