An injection molding method for a semifinished product includes a semifinished product emplacement step, a semifinished product pre-compression step and a forming step. First, a pair of mold with a forming space is provided. A semifinished product is put into the mold, and a first joint is performed to the mold by a press-fit jig, fixing the semifinished product in the forming space. The semifinished product is also tightly fitted with the mold. Next, a first open-die is performed and the press-fit jig is removed. After that, a second joint is performed, and a forming material is injected into the forming space. Finally, a second open-die is performed, and then a finished product is formed. By the semifinished product pre-compression step, the forming material can be prevented from resulting in spill or burr on the semifinished product, thereby improving the yield of injection molding.

The disclosure relates to a method for injection-molding a device, in particular a cable tie, with an integrated wireless tag, comprising the method steps of a) putting a tagging foil with two main surfaces which are separated by an edge, into a mold cavity of an open mold, where the tagging foil is held in place by a supporting device; b) closing the mold; c) injecting an injection material into the mold cavity parts adjoining the two main surfaces of the tagging foil simultaneously and symmetrically with respect to a main extension plane of the tagging foil which is parallel to the two main surfaces of the tagging foil so as to simplify and speed up the manufacturing process of a device with an integrated wireless tag or label. The disclosure furthermore relates to a corresponding molding device as well as a corresponding device with an integrated wireless tag.

An example mold assembly includes a first core, a second core, and a retaining cap. The first core defines an insert seat configured to receive a mold insert. The first core and the second core are configured to define a mold volume adjacent the mold insert. The retaining cap is disposed about a curved end portion defined by the second core, and defines a curved cap surface in contact with the curved end portion. The retaining cap is configured to secure the second core at a predetermined orientation relative to the first core within predetermined tolerances. An example technique includes positioning a mold insert in the mold assembly, disposing the retaining cap about the second core, securing the second core at a predetermined orientation relative to the first core within predetermined tolerances, and depositing mold material within the mold volume.

A golf ball 2 includes a core 4 and a cover 6 positioned outside the core 4. The cover 6 is formed in a mold having support pins by injection molding. A ratio (V/S) of a volume V (mm.sup.3) of the cover 6 to an amount of compressive deformation S (mm) of the core 4 is not less than 1000 and not greater than 1900. The cover 6 has a shore D hardness of not greater than 62. The golf ball 2 has a plurality of dimples 8 on a surface thereof. A total volume W of these dimples is not less than 490 mm.sup.3 and not greater than 620 mm.sup.3. A ratio (α/P) of a latitude α (degree) of each support pin to a total cross-sectional area P (mm.sup.2) of the support pins is not less than 0.35 and not greater than 0.60.

Provided is a bevel gear component including a plurality of teeth protruding in an axial direction, extending toward an outer peripheral side, and arranged at equal pitches in a circumferential direction, the bevel gear component including a fiber material having a shape corresponding to an arrangement pattern of the plurality of teeth and wound around a center axis.

An airbag lid reinforcing member includes a door part, a flange part, a leg part and a hinge member. The flange part surrounds an outer periphery of the door part. The leg part is arranged on the flange part. An inside surface of the leg part defines support ribs supporting the hinge member. The support ribs are arranged with a gap in a width direction of the leg part. A portion of the hinge member is buried in the flange part. In a region of the hinge member between a tip of each of the support ribs and an end surface of the flange part, at least an upper part in a thickness direction of the hinge member is exposed from the support ribs. A portion of the hinge member positioned between adjacent ones of the support ribs is exposed from the support ribs and the flange part.

An injection moulding apparatus and method for producing a moulded article is disclosed herein. In a described embodiment, the method comprises: (i) securing a layer of film to a part of a first mould half at step 504; (ii) adjusting relative position of the first mould component and a second mould component to an initial moulding position at step 506 to define a mould cavity; (iii) injecting molten moulding material into the mould cavity at step 508 to enable the molten moulding material to contact the layer of protective film; (iv) moving a movable core at step 510 to compress the molten moulding material in the mould cavity; and (v) cooling the compressed molten moulding material at step 514 to bond the layer of film to the cooled moulding material to form the moulded article.

A semiconductor package is provided which addresses problems of mold cap heel cracking. The package may made by using a cavity die and a gate insertion tool. The gate insertion tool, which fits into the cavity die, has an elongated body and includes a nozzle head with an edge which is contoured in relation to a mold cap formed on a substrate. The edge defines a curved border, for the mold cap, from a plane above the substrate to a plane lying on the substrate. The nozzle head includes a slot, for admitting a cull runner tip, centered on an axis of the elongated body.

The invention is directed to an overmolded two-component friction element in a plastic pallet and to a method for forming the pallet. The friction element includes a rigid outer carrier member and an elastomeric material that is exposed at one or more ends. The friction element is first formed in an injection mold, and then is placed in a pallet mold. Resin is injected into the pallet mold around the sides of the friction element leaving the exposed elastomeric material form part of the pallet surface.
