Abstract: A control system for controlling the operation of a molding machine and its peripheral machines. This control system automatically transmits an advance notification of for example completion of production by the molding machine to an operator by electronic mail. The system includes a destination mail address setting part and an automatic electronic mail distributing part. The destination mail address setting part automatically specifies a transmission destination before a predetermined event such as for example the completion of production at the molding machine occurs. The automatic electronic mail distributing part automatically distributes an advance notification of the predetermined event to the transmission destination before the event occurs.
