摘要： A nozzle is provided for an injection molding apparatus. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece. The nozzle body defines a nozzle body melt passage, which has an inlet that is adapted to be downstream from and in communication with a melt source. The heater is connected to said body for heating melt in said nozzle body melt passage. The tip defines a tip melt passage that is downstream from and in communication with said nozzle body melt passage. The tip melt passage has an outlet that is upstream from a gate in a mold component. The tip includes a tip sealing surface. The tip surrounding piece includes a first tip surrounding piece sealing surface. The first tip surrounding piece sealing surface and said tip sealing surface are separated by a gap. The gap is sized to inhibit the flow of melt between said first tip surrounding piece sealing surface and said tip sealing surface.

摘要： A control module is attached to a machine platen of an injection molding machine. The control module is coupled to at least one sensor that reports a value of a processing condition associated with an injection mold and is disposed within the injection mold. The control module is also coupled to at least one controllable device that varies the processing condition of the injection mold and is disposed within the injection mold. The control module collects and processes sensor output, and provides a control signal to at least one controllable device. A display interface module is linked to the control module. The display interface module accepts user-entered data set-points, provides the user-entered data set-points to the control module, and collects the processed sensor output from the control module for display to a user.

摘要： An injection molding apparatus for delivering a melt stream of moldable material to a mold cavity. A valve pin extends through a melt channel of the apparatus that is axially movable to control the melt stream within the melt channel and/or to selectively open a gate to allow communication with the mold cavity. A processing sensor is coupled to the valve pin and is axially movable therewith. By example, the processing sensor may be a pressure sensor and/or a temperature sensor for sensing processing condition(s) of the melt stream and providing sensed information to a controller.

摘要： A system and method for making molded parts that include one or more planar heaters coupled, secured, or releaseably secured to one or more sides of each of the one or more nozzles. The releasably secure coupling allows heater device to be visually inspected, tested, removed, and/or replaced. The planar heater device can have a support device patterned with an electrical resistive path. The electrical resistive path can include any pitch or number of electrical resistance lines, such that a longitudinal uniform heat profile is generated along a melt flow channel of the one or more nozzles when the nozzles are in use.

摘要： Post-mold cooling of injection molded plastic articles such as preforms is achieved by transferring the articles directly from the mold cavities onto cooling cores carried by a take-out plate. The molded articles are supported on the cooling cores until they become sufficiently frozen that they can be stripped from the cores.

The tip defines a tip melt passage therethrough, that is downstream from the nozzle body melt passage, and that is adapted to be upstream from the gate. The tip surrounding piece is removably connected with respect to said nozzle body. The mold component contacting piece is connected with respect to the nozzle body. The material of the mold component contacting piece has a thermal conductivity that is less than at least one of the thermal conductivity of the material of the tip and the thermal conductivity of the material of the tip surrounding piece.

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.
