ABSTRACT:
An injection unit for a hot-chamber die-casting machine has an injection portion with a gooseneck and a nozzle adaptor. The injector portion has a base portion at an end of the gooseneck adapted to receive a molten medium supply. A nozzle at an end of the nozzle adaptor is adapted to inject the molten medium supply in a die cavity. A channel between the base portion and nozzle is adapted to convey the molten medium supply therethrough. A piston chamber in the base portion is actuatable to draw the molten medium supply therein and to direct the molten medium supply in the channel for injection into the die cavity. An actuation portion is connected to the gooseneck to actuate the piston chamber. Heating cartridges are received in the injection portion adjacent to the channel to control temperature of the molten medium supply in the channel.
