Abstract: A cooling device and method useful for reducing the total injection molding cycle time of an injection molded tube, and more particularly to applying cooling to areas of a preform that are not in direct contact with the water cooled inside surface of a take out tube.

Abstract: A device for fracturing a defective preform for use in blowmolding is claimed. The preform has head end and a tail end and the device comprises a tube with walls defining a cavity for accepting the defective preform while the defective preform is on a core of an injection molding apparatus, an attachment element that attaches the tube to the injection molding apparatus, and locates the tube relative to the core; and a percussion instrument that contacts and breaks the defective preform at the tail end of the preform.

Abstract: The finish of plastic containers being coated with another plastic in a spray coating line is protected by shields made from a material that accumulates the sprayed coating material only slowly. The slowed accumulation increases the time intervals between required maintenance for the shields to at least as long as the intervals between other required maintenance for the spray coating line. As a result, downtime of the line just for replacement of the shields is eliminated. In addition, the shields are made from scraps of the material used to make the bottles. The shields are made by injection molding them with dimensions that take into account the inherent shrinkage of the material during cooling after removal from the mold, so that, after shrinkage, the shields fit onto the conveyor chain bottle chucks with a friction fit.
