Abstract
In a temperature control indicating apparatus of a hot runner in a thermoplastic synthetic resin injection molding system, the apparatus has a hot runner comprising a body heater, a tip heater and a temperature sensor. The hot runner is connected to a hot runner temperature control circuit having A/D converter. The apparatus has the function of arithmetic control, setting operation and display. Further, the apparatus comprises a digital control means including a microprocessor, thereby the body heater of the hot runner is digital-controlled in the process of thermoplastic synthetic resin injection molding operation.
