摘要： An injection molding system includes: an injection molding machine configured to operate in accordance with a command generated using a first language, and inject a molten material into a mold to mold a molded object; a robot configured to operate in accordance with a command generated using a second language, and convey the molded object; and a control device configured to control the injection molding machine and the robot. When determining that an error occurs in at least one of the injection molding machine and the robot, the control device transmits, to the injection molding machine, a command generated using the first language and for causing the injection molding machine to execute a return operation, and transmits, to the robot, a command interpretable by the second language and for causing the robot to execute a return operation, so as to cause the injection molding machine and the robot to execute the return operations.

摘要： A plasticizing device that plasticizes a solid material includes a drive motor, a screw rotated by the drive motor along a rotation axis of the drive motor and having a groove forming surface on which a groove is formed, a barrel having a facing surface facing the groove forming surface and provided with a communication hole in a central portion thereof, and a heating unit configured to heat at least one of the screw and the barrel. A first facing region and a second facing region that is closer to the central portion than the first facing region are provided between the groove forming surface and the facing surface. A second gap between the groove forming surface and the facing surface in the second facing region is larger than a first gap between the groove forming surface and the facing surface in the first facing region.
