Abstract: Injection molding systems described herein are configured to produce more uniform injection molded parts in one or more mold cavities corresponding to nozzles of a hot runner. The injection molding systems include sensors that detect one or more physical properties of a melt having been dispensed into the respective one or more mold cavities. A controller is configured to adjust the heat output from one or more heaters based on the sensed physical properties of the dispensed melt. Further, each nozzle of a hot runner may include a balance heater for heating an area of the nozzle body and a tip heater for heating an area of the nozzle tip. The controller of the injection molding system is configured to independently adjust the heat output of each balance heater of the hot runner.

Abstract: The present invention relates to a molding system (100) including (but not limited to): (i) an electrically chargeable conduit (102), and (ii) an electrical-charge source (104) configured to provide an electrical charge to the electrically-chargeable conduit (102), the electrical charge hastening flow of a resin (106) along the electrically-chargeable conduit (102).

Abstract: A single stand alone controller system (100) for controlling combination of hot-runner system (102) and mold assembly (104), assembly (104) connectable to system (102), controller system (100) comprising: processor (110); interface modules (112) configured to operatively couple to system (102) and assembly (104), processor (110) connected with modules (112); and controller-usable medium (114) embodying instructions (116) executable by processor (110), processor (110) connected with said medium (114), instructions (116) including: executable instructions for directing said processor (110) to control said system (102) and said assembly (104).

Abstract: An injection-molding machine (100), including: an air-open circuit (110); an air-closed circuit (112); and a pressure-equalization circuit (118) connecting with the air-open circuit (110) and the air-closed circuit (112), the pressure-equalization circuit (118) being configured to: (i) operate in a by-pass operation mode, in which the air pressure between the air-open circuit (110) and the air-closed circuit (112) becomes equalized, at least in part, by recycling, at least in part, the air pressure between the air-open circuit (110) and the air-closed circuit (112); and (ii) operate in a pass-through operation mode, in which the air pressure in the air-open circuit (110) and the air-closed circuit (112) is independently controlled.
