摘要： A system and method provide an injection molding apparatus utilizing radiation energy as a heat source. The injection molding apparatus may includes at least a partially transparent nozzle or may include a thermally conductive nozzle having a nozzle body and a nozzle channel that receives a fluid material at an inlet. The fluid material has a pressure induced flow causing the fluid material to flow along an axis of the nozzle channel from the inlet to an outlet. A radiant energy heating device heats the nozzle channel to maintain the fluid material in a fluid state.

摘要： Disclosed is a manifold of an injection molding machine. The manifold of the present invention has a groove formed on a top surface of the manifold, into which a heating wire is inserted. Protrusions are formed on both sides of an upper end of the groove and are projected from the top surface of the manifold. The protrusions fix the heating wire in such a manner that the heating wire is inserted into the groove and then the protrusions are press-fitted into the inside of the groove by pressing means such as a press or a hammer.

摘要： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater and a first gap seal surface. The nozzle body defines a nozzle body melt passage, that is adapted to be downstream from and in fluid communication with a melt source, and upstream from and in fluid communication with a gate into a mold cavity in a mold component. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The first gap seal surface is positioned on a structure that is connected at least indirectly to the nozzle body. The first gap seal surface is adapted to be separated by a gap with respect to a second gap seal surface on the mold component. The gap is sized to inhibit the flow of melt between the first gap seal surface and the second gap seal surface.

摘要： An injection molding apparatus comprises a manifold having a manifold channel for receiving a melt stream of molten material under pressure and delivering the melt stream to a nozzle channel of a nozzle. A mold cavity receives the melt stream from the nozzle and the nozzle channel communicates with the mold cavity through a mold gate. A thermocouple is coupled to the mold core of the mold cavity in order to measure the temperature of the molten material in the mold cavity.

摘要： An injection molding apparatus has a manifold and a plurality of first and second adjustable manifold blocks. The second manifold blocks are in fluid communication and are directly connected to a hot runner nozzle. The second manifold blocks are coupled to the first manifold blocks via connector devices. These connector devices contain a melt channel and allow the second manifold blocks and therefore the hot runner nozzles to be rotated relative to the first manifold blocks around at least two axes. This allows the nozzles to be positioned in front of mold gates that are located at variable elevations with respect to the manifold.

摘要： An injection molding hot runner manifold with a double or back-up heater, where each heater is capable of producing adequate heat to heat a melt channel zone. The first heater can work independently of the second heater. In one example, the second heater can function as a back-up in the event that the first heater fails, therefore extending the time before the mold has to undergo repairs.

摘要： A temperature regulator main body is connected to a cooling hole formed in a temperature regulating part under a hopper through a tube and comprises a tank for a cooling medium, a pump, a radiator, and a fan facing the radiator to send cold air and driven by a motor. By driving of the pump, the cooling medium circulates between the temperature regulating part under the hopper and the temperature regulator main body. A temperature sensor is provided to the temperature regulating part under the hopper. A controller for controlling an injection molding machine cools the circulating cooling medium by the fan and feedback controls the temperature of the temperature regulating part under the hopper when a temperature detected by the temperature sensor is higher than a preset temperature.
