FIELD: foundry, namely, precise instrument making, jewellery production and local industry branches. SUBSTANCE: injector includes pressurizable vessel with unit for heating pattern composition. Said unit is in the form of two separate heaters. One heater is placed under vessel and it is connected with manual power controller; other heater is arranged on outer lateral surface of vessel. It allows to prevent fluctuations of current temperature from preset value. Optimal relations of heat conductivity and thermal capacity values are selected for materials of vessel and of union for feeding pattern composition. Injector may be quickly and accurately set to predetermined working mode and said mode may be sustained if necessary. EFFECT: improved design, enhanced characteristics of injector. 1 dwg
