The present invention is intended to provide a manufacturing method of an insert molded article that makes it possible to manufacture efficiently the insert molded article including a metallic insert, an inside member made of a synthetic resin and covering a portion of the insert, and an outside member made of a synthetic resin different from the material of the inside member and covering a portion of the inside member using general molding machines, not a dedicated two-color molding machine.

General molding machines are used to manufacture the insert molded article formed by injection molding of a resin part in twice. An insert core 7 is used in common in primary molding using a primary molding die C1 and in a secondary molding using a secondary molding die. A round shaft 7C of the insert core 7 is fitted into an internal hole 2C of an insert 2 to form a coupled body 10 in which the insert 2 and the insert core 7 are coupled together. The coupled body 10 is used in common at the primary molding step and the secondary molding step.

A molded resin body for surface-mounted light-emitting device has a cured resin body integrally molded with a plurality of leads and a concave portion to which the plurality of leads are exposed at the bottom portion, in which the ten-point average roughness (Rz) of the opening surface of the concave portion is 1 μm to 10 μm, the glass transition temperature of the cured resin body is 10° C. or higher and the glass transition temperature is a value measured using a thermomechanical analyzer (TMA) under the conditions of a temperature range of −50 to 250° C., a temperature elevation rate of 5° C./min, and a sample size length of 1 to 5 mm, and the optical reflectance at 460 nm of the opening surface of the concave portion is 80% or more and the optical reflectance retention rate on the opening surface after heating the molded resin body at 180° C. for 72 hours is 90% or more.

The present invention is directed to a golf ball having a non-planar parting line on its spherical surface.

A method and device for injection moulding micro-components, including an injection moulding machine having a mould carrier, which supports a removable mould in which at least one mould cavity is provided; and a counter mould, which is arranged so as to be closed against the mould in such a way as to apply a centering force as well as moulding pressure to the mould when the counter mould is closed against the mould.

A process produces an electrical line which extends in the longitudinal direction and the line has a line core and an outer shell. In a continuous shaping process, individual shell portions of the outer shell are formed successively by surrounding the line core with a curable plastic substance. In at least one portion, the outer shell is produced having a cross-sectional geometry which can be varied in the longitudinal direction of the line.

A component with a customized exterior surface and a method and tool for manufacturing the same are provided. The component may be formed via a plastic forming process with a forming tool, such that it has a surface texture formed on its exterior surface. The forming tool has at least one tool surface, which defines a mold cavity. The tool surface has a textured layer coupled thereto, such that the textured layer directly contacts a moldable material supplied to the mold cavity. The textured layer has a surface texture formed thereon resulting in the surface texture present on the textured layer being transferred to and formed on the exterior surface of the component during forming. The textured layer may be changeable or replaceable with respect to the at least one tool surface, such that a single tool may form components with different surface textures formed on the exterior surface thereof.
