Abstract: A screw is provided for an injection unit having an inner diameter surface and a raised outer diameter surface on the screw flights. Carbide inserts such as a carbide wire or a plurality of short carbide inserts are mounted to the outer diameter surface to reduce wear on both the screw flights and the inner surface of the extrusion barrel.

Abstract: Disclosed is, according to an aspect, a metal-molded article, including: (i) a body molded in association with a mold assembly, and (ii) a hollow insert embedded, at least in part, in the body. The body has a light-metal alloy that was injected, under pressure, into the mold assembly.

Abstract: An injection nozzle is provided having a nozzle body, defining an inlet channel, an outlet channel and a connecting channel therebetween for communicating a working fluid into and out of the nozzle body. A shut-off pin is slidably mounted within the nozzle body and having a spigot mounted thereto. The shut-off pin is movable between a closed position, where the working fluid is substantially blocked from moving from the inlet channel to the outlet channel, and an open position where the spigot is withdrawn, unblocking the working fluid from moving from the inlet channel to the outlet channel. An actuator is operably connected to the shut-off pin to move the shut-off pin from the open position to the closed position. Moving the shut-off pin from the open position to the closed position generates a region of low pressure in the working fluid in the portion of working fluid trailing the spigot.

Abstract: Disclosed is a method of a mold-spraying apparatus for use with a molding apparatus. The mold-spraying apparatus has: (i) a spray nozzle, (ii) a rotatable shaft being supportive of the spray nozzle, and (ii) a camming surface. The method includes: (a) engaging the rotatable shaft with the camming surface, and (b) moving the camming surface so that the rotatable shaft may rotate.

Abstract: Disclosed herein is an apparatus of a molding system and a molding system. The apparatus and the system each include a plurality of mandrels. A selected mandrel of the plurality of mandrels is configured to rotate differently from a manner in which another selected mandrel of the plurality of mandrels is configured to rotate.

Abstract: A simplified perform handling device including an end-effector arranged to substantially conform, in use, to an end portion of a preform and to seal therewith. The device also includes an aligning jig to align the preform with the end-effector. The device provides improved preform thermal and angular orientation characteristics when used in a transfer apparatus of an injection blow molding system, or simplified end-of-arm tool for two-stage preform production. The device may also be operated to condition a preform retained on the injection mold core plate assembly of an injection mold.
