Abstract: A molded article suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion; a gate portion; and a body portion extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article into the final-shaped container.

Abstract: A method of heating plastic blanks for molding comprises, for each blank in a sequence of blanks of different types, determining a heating requirement corresponding to characteristics of the blank a molding process to be applied and heating each blank according to its heating requirement. A microwave field is generated having a defined heating rate, and the blank is placed in the microwave field for a period of time equal to the heating duration, such that the heating duration and the heating rate correspond to the heating requirement.

Abstract: Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

Abstract: A plastic molding method comprises moving each part of a plurality of parts along a selected one of a plurality of possible paths through dispensing and molding stations of a molding system. A controller tracks an operating state of each station, selects process stations capable of receiving a part for processing; identifies parts capable of processing at the selected process stations, and assigns individual parts to individual process stations.

Abstract: A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.
