The resin injection gate is disposed at the pillar part. When the bearing cage is divided into first and second regions by an imaginary line connecting the resin injection gate and a weld to be formed at a position radially facing the resin injection gate, a resin reservoir that can store therein the melted resin is formed at the pillar part in only one of the regions. A circumferential distance between the resin reservoir and the weld is smaller than a circumferential distance between the resin reservoir and the resin injection gate. A cross-sectional area of a communicating part of the resin reservoir, which is configured to communicate with the pillar part, is equal to or less than a quarter of a cross-sectional area of the resin injection gate.

A method of manufacturing an electronic device includes a step of housing an electronic component in a metal mold, then filling the metal mold with a molding material, wherein the metal mold includes a cavity having a rectangular planar shape and housing the electronic component, and a dummy cavity communicated with a side surface having the smallest gap with the electronic component out of four side surfaces included in the cavity, and in the step of filling the metal mold with the molding material, the molding material inflows into the cavity, and the molding material in the cavity inflows into the dummy cavity.

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.

An injection molding apparatus including a mold, an injection device and at least one sensor is provided. The mold has a mold cavity. The injection device is adapted to inject a material into the mold cavity such that the material is formed into a forming article. The at least one sensor is disposed on the mold and adapted to sense at least one of a temperature and a pressure in the mold cavity. The at least one sensor is located at an inner surface of the mold cavity and corresponds to a non-appearance surface of the forming article. In addition, an injection molding method is also provided.

The invention relates to a mold (200) for producing a foam cladding (120) made of plastic on a planar component (100) or for producing a foamed plastic part (120), comprising a mixing head (300) for producing liquid plastic from at least two components, at least one first cavity (240) for receiving the plastic in order to form the foam cladding (120) or to produce the foamed plastic part (120), a sprue channel (210) for connecting the mixing head (300) to the at least one first cavity (240), and a further cavity (220), which is formed at the transition of the sprue channel (210) to the first cavity (240) and widens the sprue channel (210). For automated cutting of a tag-like sprue, which would otherwise adhere to the foam cladding, the invention provides that a sprue cutter (400) having at least one slide (410) is movably mounted on the mold (200), which slide can be moved by means of at least one actuating cylinder (450) in the direction of the sprue channel (210) toward the first cavity (240) and, in an end position of the movement of the slide, closes off the first cavity (240) from the sprue channel (210) and/or from the further cavity (220) by means of at least one edge (414) and/or contour (412).

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.

An object of the present invention is to provide a technique by which, when producing a resin molded article using an insert member having low pressure resistance, molding can be easily performed, and deformation of the insert member can be suppressed. A method for producing a resin molded article of the present invention, the method includes the steps of disposing an insert member in a cavity of a mold; performing injection of molten resin into the cavity; terminating the injection on and after the molten resin reaches an overflow portion in the cavity and before the molten resin fills the overflow portion; and separating resin in the overflow portion.

A mold, system and method for manufacturing a part includes injection molding a substrate in a single injection mold and optionally trimming the panel substrate. The substrate can have a first configuration or a second, different configuration. Trimming of the substrate can occur when the substrate has the first configuration to define an aperture in the substrate.

A method of over-molding a thermoplastic elastomer over fabric includes: precision forming a mold cavity to match the final dimensions of a finished product; cutting a piece of fabric to a correct size; fixedly securing the fabric piece in the mold cavity; and injecting a thermoplastic elastomer into the mold cavity at an appropriate temperature and pressure, on top of the fabric piece. The method may further include heating the thermoplastic elastomer to a temperature for melting a surface layer of the fabric when injected thereon, and cooling of the thermoplastic elastomer and fabric for bonding of the thermoplastic elastomer to the surface of the fabric. The method may further include adding one or more additives from the group of additives consisting of: a UV stabilizer, an anti-blocking agent, a slip agents, a plasticizer, and a flame retardant; and securing a cord member onto an exposed portion of the fabric.
