Injection molding system and method for manufacturing molded object

An injection molding system comprising:

• an injection molding machine configured to operate in accordance with a command generated using a first language, and inject a molten material from a nozzle 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 molded by the injection molding machine;
• and
• a control device configured to transmit the command generated using the first language to the injection molding machine to control the injection molding machine, and transmit a command interpretable by the second language to the robot to control the robot, wherein
• when determining that an error occurs in at least one of the injection molding machine and the robot, the control device is configured to transmit, 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 transmit, 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, and
• the control device is configured to execute the return operations of the injection molding machine and the robot so as to overlap a period during which the return operation of the injection molding machine is performed and a period during which the return operation of the robot is performed.
