A method and apparatus for producing hollow articles made of injection moulded plastic material by a mould having a die within which there is inserted a core, and at least one injector including a pin valve displaceable between a closing position and an opening position for injecting the pressurized plastic material into a space comprised between the die and the core. During the injection, any flexural deflection of the core is detected and the pin valve of the or of each injector is displaced in a controlled fashion to adjust a pressure and a flow rate of the injected plastic material, so as to reduce or eliminate such deflection of the core.

An insert molding component includes a primary molding section having a concave portion formed in one surface thereof, the concave portion including stepped lower and upper concave portions, an insert component disposed on a bottom surface of the lower concave portion, a heat-insulating component disposed in the upper concave portion above an opening of the lower concave portion in which the insert component is disposed, and a secondary molding section disposed in contact with the one surface of the primary molding section.

An injection molded composite component includes a groove extending from a first surface of the composite component and a tubing material placed within the groove and formed integrally with the composite component such that the tubing material forms an integrated conduit on the first surface of the composite component.

A fixing member-attached resin pipe manufacturing method including a process of placing a part of a resin pipe inside a mold for molding a fixing member, and a process of causing a molten resin to flow into the mold so as to mold the fixing member in a state in which the resin pipe is pressurized from an inside of the resin pipe by supplying a fluid into the resin pipe.

The invention relates to a method for producing decorative parts with a rear plastic carrier element, which is poured over with plastic under process pressure in a casting tool for producing an upper layer on a front visible side, characterized in that the carrier element is fixed in the casting tool and is impinged upon with pressure at least during the production of the upper layer at the rear and in the direction of the upper layer that is to be produced on the front visible side, said pressure counteracting the process pressure during the overmolding with plastic.

According to one embodiment, a method for manufacturing an iron core product includes providing an iron core body which includes a magnet insertion hole in which a permanent magnet is disposed, injecting a molten resin into the magnet insertion hole of the iron core body at a first pressure, and setting a pressure applied to the molten resin to a second pressure lower than the first pressure after the molten resin is injected into the magnet insertion hole and before the molten resin is cured.

An insert-molded container in which a secondary container made of transparent synthetic resin is integrally provided to the outside of a primary container, the secondary container includes a gate mark, and a vapor-deposited layer is provided on the outer surface of the primary container in a peripheral area of the gate mark is manufactured by a manufacturing method of insert-molded container. The method includes: a cover attaching step of attaching a cover member made of transparent synthetic resin to the outer surface of a part of the primary container where a vapor-deposited layer is provided; a placing step of placing the primary container in a mold with the cover member facing a gate; and an insert molding step of injecting a transparent synthetic resin material from the gate.

A connector device that includes a circuit board; a connector attached to the circuit board; a plurality of collars for external attachment; a first molded resin that is made of a first resin material whose melting point or softening point is 230° C. or less, and covers the entire circuit board and part of the connector; and a second molded resin that is welded to the first molded resin, is made of a second resin material whose melting point or softening point is higher than that of the first resin material for the first molded resin, and covers outer circumferences of the collars.

An injection mold for encapsulating a substrate comprises a lower mold component and an upper mold component adapted to form an encapsulation mold at an edge of the substrate when the upper mold component engages the lower mold component. The lower mold component comprises a substrate support and wherein the upper mold component comprises a recess. The injection mold includes a tiltable insert sized and shaped to slide within the recess to form a seal for the encapsulation mold, the insert having a substrate-contacting surface defining an area of the substrate contacted by the insert. The injection mold includes a plurality of pressure-exerting actuators connected to the tiltable insert and each being configured to independently apply pressure on the substrate via the insert, wherein the plurality of pressure-exerting actuators are adapted to equilibrate a total predetermined pressure exerted by the insert substantially evenly across the area of the substrate-contacting surface.
