摘要： A manifold for a hot process injection molding apparatus includes a two piece manifold assembly. A first manifold section which includes a longitudinal melt channel and a nozzle drop to a mold is fixably secured to a manifold cavity of the apparatus. A second manifold section also including a longitudinal melt channel is sealably and slidably coupled with the first manifold section for fluidly communicating molding material from the second melt channel to the first melt channel. Expansion and contraction of the manifold sections are taken up by the slidable coupling.

摘要： A multi-colored lens assembly is produced in a multi-station injection molding apparatus having non-indexing ejector halves and indexing cover halves. Material is shot on an unexposed illumination side of the lens assembly from valve gated nozzle drops contained in the non-indexing ejector halves thereby producing a viewing side of the lens assembly free of surface blemishes and surface stress defects. Lens assemblies are retained in the indexing cover halves by retention mechanisms provided to overlap peripherally extreme features of the lens assemblies. Lens assemblies are affirmatively released from the non-indexing ejector halves by ejection pins or blades simultaneously with parting of the mold halves.
