摘要： An injection moulding apparatus (10) includes similar co-injection modules (12) each provided with common supplies (238-242) and supplied with different polymer materials at intermediate pressure by common plasticisers (14-18). Each module has a co-injection nozzle assembly (70) in wich each nozzle (148-154) is supplied with polymer at injection pressure by an injector (208) which receives polymer through a non-return valve (220). The injector is mounted alongside the nozzle on a polymer transfer plate (138-146), and has the position of its piston (212) controlled by a hydraulic actuator (214) under the control of a dedicated micro-processor (164) in accordance with a stored injection control program. Each polymer is injected by an injector (208) directly into the associated nozzle (148-154) and is controlled solely by injector operation, and without the use of any control valve between the injector and the nozzle. The module micro-processors are controlled by a host processor which organizes the operations of the apparatus.

摘要： Methods of injecting into a cavity an at least three-layer flow stream having a fast flow stream line, are provided which include establishing the flow of material of first and second layers of the flow stream to form an interface therebetween at a first location not coincident with the fast flow stream line, interposing the flow of material of a third layer in the interface, and moving the third layer to a second location relatively more proximate to, substantially coincident with, or across from and not substantially coincident with the fast flow stream line. This moving achieves foldover of the third layer and can be effected by selectively changing the flow of material(s) on one side of the third layer relative to the flow of material(s) on the other side thereof, at or shortly after the interposition of the third layer. Preferably, the interface is annular and the interposition is at substantially all places around the interface. These methods can be used to prevent, reduce or overcome bias of the terminal or marginal end portion of the third layer during multi-layer injection of a container, to provide a substantially unbiased overall leading edge of the third layer, such that the folded over portion and the unfolded portion of the marginal end portion is finally positioned in the sidewall of the container in a substantially unbiased plane relative to the axis of the container.

摘要： An injection molding machine for simultaneously injection molding a plurality of articles each made of plural polymeric materials. The injection molding machine includes a source of a first polymeric material and a source of a second polymeric material. The injection molding machine also includes a plurality of co-injection nozzles, each of the nozzles has an associated injection cavity mold. Each of the nozzles also has a first flow channel for providing a stream of said first polymeric material to said mold and a second flow channel for providing a stream of said second polymeric material to said mold. The machine further includes a manifold for feeding the polymeric materials from their sources to each of the nozzles and each of the associated molds, such that each of the streams of the first polymeric materials flows from each nozzles into each associated mold simultaneously and each of the streams of the second polymeric materials flows from each nozzle into each associated mold simultaneously.
