摘要： An apparatus and method for a hot runner injection molding system. The injection molding system has a plurality of melt conveying components defining a melt path from a melt source to a mold cavity and a mold housing. A force sensor or load cell is utilized between at least one melt conveying component of the system and the mold housing to measure a force generated due to thermal expansion of the melt conveying component during start-up and/or operation of the system and to provide an output to a receiving device. In an embodiment, once a sealing load or a predetermined preload force has been reached, an injection molding cycle may begin.

摘要： An injection molding hot runner apparatus and insert assembly for use in a manifold of the apparatus. The apparatus includes a mold manifold, a cylindrical insert for redirecting melt within the mold manifold, and an expandable sleeve surrounding the insert. When the manifold, insert and sleeve are heated to an operational temperature (e.g. 300° C.), the sleeve expands to create a fluid tight seal between the manifold and the insert. The insert assembly including the insert and sleeve is mountable in the mold manifold to redirect melt.

摘要： A valve-gated nozzle for an injection molding machine includes an annular flow channel between downstream portions of a nozzle liner and a sealing and/or retaining device. The nozzle liner includes a first melt channel and one or more second melt channels for communicating a melt stream to the annular melt channel. The annular melt channel is formed between an inner surface of the downstream portion of the sealing and/or retaining device and an outer surface of the downstream portion of the nozzle liner. The annular melt channel may include a groove within at least one of the inner surface of the sealing/retaining device and the outer surface of the nozzle liner, such that the groove is in communication with an outlet of the second melt channel to thereby guide and/or blend the molten material within the annular melt channel to even and balance flow into a mold cavity.

摘要： A nozzle for an injection molding apparatus is provided. The nozzle includes a nozzle body, a heater, a tip, a tip surrounding piece and a seal piece. The nozzle body defines a nozzle body melt passage, which is adapted to be in fluid communication with an upstream melt source. The heater is thermally connected to the nozzle body for heating melt in the nozzle body melt passage. The tip is removably connected to the nozzle body. The tip defines a tip melt passage therethrough. The tip melt passage is downstream from and in fluid communication with the nozzle body melt passage, and is adapted to be upstream from and in fluid communication with a mold cavity in a mold component. The tip surrounding piece is removably connected with respect to the nozzle body. The tip surrounding piece is spaced from said tip. The seal piece is positioned between the tip and the tip surrounding piece. The seal piece forms a seal with the tip and with the tip surrounding piece to inhibit melt leakage between the seal piece and the tip and between the seal piece and the tip surrounding piece, so that, in use, at least a portion of the tip and the tip surrounding piece are separated by an air gap.
