Disclosed, amongst other things, is a melt distribution apparatus of a hot runner and a related method for balancing melt flow to a plurality of drops. The melt distribution apparatus includes a plurality of chokes with each choke of the plurality of chokes being associated with a corresponding one of a drop of a plurality of drops. Each choke of the plurality of chokes being configured to contribute, during an injection of a molding material therethrough, a choke melt-pressure loss such that the plurality of chokes contribute an aggregate choke melt-pressure loss that is generally between 10% and 75% of an aggregate hot runner melt-pressure loss.

Melt distribution apparatus for use in a hot runner

A system and method for providing on demand information exchange between a data store and a portable recipient data storage device includes a source of data and a data transfer initiator, coupled to the source of data and configured for initiating the transfer of data from the source of data to a portable recipient data storage device. A data transfer port is provided to couple the data source with the portable recipient data storage device, and configured for transmitting, on request by the recipient, data from the source of data to the portable recipient data storage device.

Information exchange system and method

A hot runner system having a melt distribution system that is reusable and reconfigurable to vary drop or nozzle locations to meet various design requirements. The melt distribution system includes a melt distributor in fluid communication with a melt source, at least one melt conduit in fluid communication with the melt distributor, and at least one nozzle in fluid communication with the at least one melt conduit. The hot runner system also includes a backing plate; a manifold plate detachably connected to the backing plate; a melt distribution system positioned between the backing plate and the manifold plate and having at least one nozzle associated therewith. The hot runner system may be configured and reconfigured to accommodate various drop or nozzle locations.

Reconfigurable hot runner

A flexible plate system for a hot runner assembly includes a backing plate; a manifold plate detachably connected to the backing plate; a manifold positioned between the backing plate and the manifold plate and having at least one nozzle associated therewith; and wherein the manifold plate has at least one plate slot that allows the nozzle to extend through the manifold plate and having at least a first lateral dimension substantially larger than the outside diameter of the nozzle. The manifold plate and the backing plate may be configured to have at least one manifold plate cavity and at least one backing plate cavity to accept at least one nozzle insert and at least one piston cylinder insert respectively, the nozzle insert having a nozzle bore or a plurality of insert slots therethrough for installation of the nozzle, and the piston cylinder insert having a cylinder bore for a piston cylinder.

Flexible plate slot for a hot runner injection molding system

An injection molding machine system includes a hot runner comprising a memory device configured to contain at least one process control parameter. The memory device may transmit a signal representative of the process control parameter to a machine controller associated with the injection molding machine system. The machine controller may generate control signal to operate the injection molding machine system based on, at least in part, the signal from the memory device, wherein the at least one memory device is pre-programmed to have the information pertaining to the at least one process control parameter prior to a first run in the injection molding system.
