A method for manufacturing a component with moulded-on seal, in particular a pump component. The component is laid in an injection-moulding tool, then a sealing material is injected from an injection gate into the injection-moulding tool and fills a cavity on one side of the component. Sufficient sealing material is injected for a part of the sealing material to pass from the cavity, via an overflow channel connected to the cavity, into an overflow chamber which is provided inside the contour of the component. A component can includes the moulded-on seal.

The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.

An injection mould and an injection moulding method are provided. The injection mould includes a base plate used to place a packaged chip to be injection moulded including a substrate and at least one of the chips fixed on the front substrate by a flip chip process. The substrate has a gas hole. Two or more gas ducts that extend in at least two intersected directions and connect with one another are formed in the base plate. Two ends of each one of gas ducts are open, and at least one of the gas ducts is buried into the base plate. Each one of gas ducts is provided with a gas outlet. When the packaged chip is placed on the base plate, the gas outlet connects with the gas hole of the substrate.

A resin detection system for closing an automated valve to prevent resin entering a vacuum line portion of an outlet line is described. The resin detection system comprises a support (300) to a pneumatically-actuated device (320), a capacitive sensor (380) and a valve (410) are mounted. The sensor is configured to provide at least one signal indicative of the presence of resin in the outlet line which is used to close the valve automatically once the presence of resin is sensed by the capacitive sensor. The resin detection system forms part of an injection moulding apparatus and receives signals from a processor thereof to ensure that, if too much resin is injected, the valve is automatically closed even in the event that the sensor does not detect the presence of resin in the outlet line.

The invention relates to a method for producing a liquid con-tainer (2) for a motor vehicle, which is assembled from at least two shells (4, 6). Furthermore, the invention relates to a liquid container (2) for a motor vehicle.

This invention relates generally to an apparatus for casting a portion of a tire or other article of manufacture, and, more specifically, to an apparatus that has a gate design that has a circular runner and concentric channel or waste reservoir for separating off-ratio material before it enters the cavity that forms a portion of the fire or oilier article of manufacture. The design may further include a passage that connects the runner to the waste reservoir as well as an air vent that allows trapped gas or air to exit the waste reservoir as it fills with waste material, a valve that Is operative!) associated with the passage for closing and opening the passage at appropriate times, and a nozzle for initially introducing material into the waste reservoir and subsequently into runner.

A method for molding a connector boot over a connector of a wire harness comprises positioning the connector of the wire harness into a mold cavity of a mold. A resin mixture is de-aerated to provide a de-aerated resin mixture including a synthetic resin and a hardener. The de-aerated resin mixture is injected into the mold cavity to gradually fill the mold cavity from bottom to top. The injected de-aerated resin mixture is then allowed to harden to form the connector boot around the connector of the wire harness under isothermal conditions. Once cured, the connector boot is demolded.

In this pump apparatus, each of plural gate marks formed in a second blade member is formed at an intermediate position in a circumferential direction of a rotor between two blades that are adjacent to each other in the circumferential direction of the rotor, and the even number of blades are disposed between the gate marks in the circumferential direction of the rotor. The plural gate marks are disposed on an outer side, in the radial direction of the rotor, of an outer circumferential surface of a portion, which is connected to the second blade member, in a magnet holding member formed in a tubular shape.
