Abstract
A plasticizing apparatus includes a drive motor, a rotor rotated by the drive motor and having a groove-forming surface provided with a groove, a barrel facing the groove-forming surface and having a communication hole, an enclosure that accommodates the rotor, a heating section that heats a material, and a wear suppressor provided in at least one of the portion between the rotor and the barrel and the portion between the rotor and the enclosure. When the wear suppressor is provided between the rotor and the barrel, the wear suppressor is fixed to the rotor or the barrel and has Vickers hardness higher than the Vickers hardness of one of the rotor and the barrel, the one to which the wear suppressor is fixed, whereas when the wear suppressor is provided between the rotor and the enclosure, the wear suppressor is fixed to the rotor or the enclosure and has Vickers hardness higher than the Vickers hardness of one of the rotor and the enclosure, the one to which the wear suppressor is fixed.
