Improved injection molding methods and molds, for forming TPU layers, especially thin TPU covers, into golf ball constructions, and having improved number, shape and placement of both the injection gates and the cold slugs within the mold in order to minimize/eliminate damage to dimples strategically positioned close to the parting line of a mold in order to maximize aerodynamic properties of the resulting golf ball.

A tool system for producing a workpiece by injection-molding includes: a tool part which has a cavity for shaping the workpiece from an injection-molding compound; and an adjusting device, which has a drive, a drive shaft, and a plurality of adjusting elements which are operatively connected to the drive shaft and are adjustable via the drive shaft. Driven by the drive, the adjusting elements, each with an actuating section for acting on at least one portion of the workpiece, are adjustable relative to the cavity.

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.

A method of fabricating an optical assembly includes positioning an optical structure between a first portion of a mold tool and a second portion of the mold tool and providing a transparent liquid optical material into a first cavity of the mold tool and into the second cavity of the mold tool while the optical structure is positioned between the first portion of the mold tool and the second portion of the mold tool. The first cavity is defined by the first portion of the mold tool and the second cavity is defined by the second portion of the mold tool. The liquid optical material is cured to form the optical assembly.

A method forms a frame of a seat back for a vehicle. The frame includes a first polymeric material and a reinforcing composite layer that includes a second polymeric material and a plurality of fibers impregnated in the second polymeric material. The method includes the steps of supporting the reinforcing composite layer on moveable members in a mold and extending the moveable members relative to the mold to an extended position in the mold. The method also includes the steps of introducing the first polymeric material in a molten state into the mold and into contact with the reinforcing composite layer and displacing the reinforcing composite layer away from the moveable members by introducing the first polymeric material in the molten state between the moveable members and the reinforcing composite layer while the moveable members are in the extended position. The method further includes the steps of causing the first polymeric material to solidify in the mold and retracting the moveable members from the first polymeric material.
