Abstract: An injection apparatus is configured to feed a molten resin into an injection molding section of an injection stretch blow molding machine. The injection apparatus uniformly melts a resin material while the duration from the time of starting plasticizing and kneading till completion of injection is shortened, thereby allowing the operation of the injection apparatus to fall within the time corresponding to the reduced injection molding process in the injection stretch blow molding machine. Thus, the molding cycle for a hollow body is reduced. In this context, at the start of the filling for each injection cycle, the injection apparatus starts plasticizing and kneading for generating the molten resin for injection in the next injection cycle.

Abstract: An apparatus and method for establishing triggers for the opening of one or multiple gates to a mold cavity of an injection molding system, followed by a sequence of predetermined valve pin movements over the course on an injection cycle. In one embodiment, the invention provides a graphical user interface and control system enabling a user to select from and arrange a plurality of virtual icons into a user-defined virtual sequence that define associated triggering events and actuator controlled pin movements over the course of an injection cycle. In various embodiments, the apparatus and method allows the system operator to view a simulated profile of such triggers and movements and to compare the simulated profile to an actual profile to access differences and make adjustments to the triggers and sequencing more quickly and efficiently. This is particularly useful in sequential molding systems where multiple gates need to be programmed and adjusted to compensate for variations from a predetermined sequence.

Abstract: A low pull force system for feeding a filament along a feed path from a source to a liquefier in a 3D printer includes a low compressive force loading drive for advancing filament from the source, a feed drive for advancing filament into the liquefier, and an in-line accumulator comprising a telescoping joint positioned in the feed path between the loading drive and the feed drive.
