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 system and injection molding method for making molded parts that include one or more planar heaters having a thin or a thick film resistive heater element coupled, secured, or releaseably secured to one or more sides of each of the one or more injection molding 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 a film 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 injection molding nozzles when the nozzles are in use. In some examples, the planar heater has more than one film resistive heater element that can be coupled to one or each side of a nozzle, with dielectric material interposed between the planar film resistive heater elements. This can allow for additional or alternative heating in various applications.

A manifold nozzle tubular connector is receivable at a first end within a manifold and at a second end within a nozzle and has a length that bridges a space between opposing surfaces of the manifold and nozzle. The first end of the tubular connector may be threadably and/or permanently attached within a manifold bore in a downstream surface of the manifold with the second end of the tubular connector being slidably received within a nozzle bore in an upstream surface of the nozzle or within a nozzle melt channel. Alternatively, the first end of the tubular connector may be slidably received within a manifold bore in the downstream surface of the manifold or within a manifold melt channel with the second end of the tubular connector being threadably and/or permanently attached within a nozzle bore in an upstream surface of the nozzle.
