Abstract: A manifold system (50) comprising a main manifold (56) with a plurality of arms (64), a plurality of sub-manifolds (52) spaced from the main manifold (56) and communicating with the main manifold (56) through a plurality of melt transfer bushings (68) disposed between the main manifold (56) and the sub-manifolds (52). The melt transfer bushings (68) may include static mixers (140) to homogenize the melt. An air plate (70) is disposed between a backing plate (58) preferably housing the main manifold (56) and a manifold plate (54) preferably housing the sub-manifolds (52). The air plate (70) has a plurality of air channels (74) that communicate with valve gate nozzle actuators (90), which are received in actuator cavities (72) in the air plate (70). The air plate (70) is bolted to the manifold plate (54), and the backing plate (58) is bolted to the air plate (70) with bolting patterns not constrained by location of the main manifold (56) or sub-manifolds (52). The manifold system (50), as shown in FIG.

Abstract: Disclosed herein is a molded article handling device, an apparatus, and a system. The device, the apparatus and the system include a slide bar configured to have a mold portion configured to mold, in cooperation with complementary mold halves of a molding machine, a molded article. The slide bar is also configured to be actuatable by an actuator. The actuator is configured to move the slide bar towards selectable positions, and the selectable positions located between travel terminus points.

Abstract: An injection molding shooting pot shot size control apparatus is configured to be installed in a coinjection hot runner with a coinjection nozzle, the coinjection nozzle having at least two melt channels ending at the same gate includes a valve inlet and a valve outlet. An adjustable melt control mechanism, preferably in the form of a hydraulically actuated wedge, is configured to (i) be disposed in a cavity plate adjacent to a hot runner assembly, and allow the shot size position to be set while the mold is open, and (ii) permit the charged shooting pot cylinder to decompress the melt when the wedge is pulled away from the shooting pot piston.

Abstract: An injection molding shooting pot assembly check valve configured to be installed in a coinjection hot runner with a coinjection nozzle, the coinjection nozzle having at least two melt channels ending at the same gate includes a valve inlet and a valve outlet. A check valve occlusion (preferably a ball) is configured to (i) be disposed integral with or immediately adjacent the shooting pot assembly, and (ii) prevent resin leakage to the valve inlet in response to a melt discharge operation of the shooting pot assembly. Preferably, more than one such shooting pot assembly with integral check valve is provided in a coinjection molding machine.

Abstract: An injection molding sealing apparatus configured to be installed in a coinjection hot runner with a coinjection nozzle, the coinjection nozzle having at least two melt channels ending at the same gate. The sealing apparatus is configured for sealing the coinjection hot runner to a hot runner sprue bushing, which is coupled to an injection assembly, during relative movement between (i) the coinjection hot runner and (ii) a stationary mold or machine section. Sealing structure is configured to seal the coinjection molding hot runner sprue bushing to the coinjection hot runner during the relative movement. Coupling structure is configured to provide relative movement between the injection assembly and the stationary mold or machine section.
