摘要： A cylindrical switch has one or more passages which open onto a lateral cylindrical surface of the switch. The switch is capable of being tightly received in a cylindrical hole in a hot plate and of being selectively orientated so that the passages are angularly in line with or offset from two or more channels in the hot plate which open onto the hole in order to selectively permit, interrupt or divert the flow of molten plastics material between the aforesaid channels. The switch incorporates a circuit for a cooling fluid.

摘要： Disclosed herein are methods and systems for forming a plurality of multiple layer plastic articles. The methods and systems utilize shooting pot technology in combination with a combination of thermal control elements and in some instances, specialized flow bore geometries to control a thermal property and a flow parameter of selected polymeric material flowing through the system to mold the plurality of multiple layer plastic articles. Both the systems and methods are well suited for use to perform simultaneous flow injection or sequential flow injection to form the plurality of multiple layer plastic articles. The systems and methods described therein beneficially reduce the mold cavity pitch size for multiple layer molds used with systems having shooting pot technology to a mold cavity pitch size found on conventional monolayer molds to provide a plurality of multiple layer plastic articles having a cost similar to monolayer plastic articles.

摘要： A method for producing components for injection moulding comprising a body made of thermally conducting material with expansion coefficient matching that of the insulating layers and provided with a passage for the material to be injected. At least one strip of electrically conducting material with high change of resistance with temperature, forming a heating resistor or inductor is applied on a electrically insulating base layer previously directly applied on the body. At least one final insulating layer with low thermal emissivity is then applied to optimise electrical efficiency. The method utilises thermal spray techniques and can be applied also for production of other heating equipment.

摘要： Coinjection molding shooting pot cooling apparatus and method are configured to cool a shooting pot cylinder which, in combination with a shooting pot piston, injects a melt through a coinjection nozzle having at least two melt channels ending at the same gate. Preferably, a heat sink sleeve is disposed to contact an outer surface of a rear portion of the shooting pot cylinder. The heat sink sleeve is configured to remove sufficient heat from the shooting pot cylinder to increase the viscosity of the melt therein, thus reducing melt leakage between the shooting pot piston and the shooting pot cylinder.

摘要： An injection molding apparatus used comprises a molten resin injector 15 for injecting a molten resin, and a die 12 connected to the molten resin injector and communicating with the molten resin injector so that the molten resin is injected into the die. A cavity having a prescribed shape is formed within the die in order to mold the injected molten resin into the prescribed shape. An opening of the die for guiding the molten resin to the outside is blocked so as to confine a molding object as an object for molding the resin member. A plate member 10 as a molding object is compressed onto the die 12, and the molten resin is injected into the die while compressing the molding object. The molten resin is adhered on the molding object by being guided from the opening, and a solidified resin member comprising the solidified molten resin is bonded on the surface of the molding object. Consequently, the resin member having a prescribed shape is readily and promptly formed on the surface of the molding object.
