A method of manufacturing an in-mold decorative molded article capable of transferring a decorative pattern with target dimensions at a target position of a decorative molded article according to the present disclosure includes supplying an in-mold transfer foil to a metal mold, in which a clear layer having transparency and lower extensibility than a base material film is formed in the first layer on an in-mold raw fabric configured by forming a mold releasing layer and a primer layer on the base material film and a decorative figure is printed in the second and subsequent layers on the in-mold raw fabric, clamping the metal mold, injecting and cooling a molding resin and taking out an molded article formed of the molding resin cooled and cured in the metal mold in which the clear layer and a transfer layer having the decorative figure in the in-mold transfer foil are integrated on the surface by opening the mold, molding the molded article integrally with a cutting portion not necessary for a target product inside the metal mold by the molding resin at an outer periphery of the product and arranging a boundary of a printing region of the clear layer in the in-mold transfer foil in the cutting portion so as to be larger than the outer periphery of the product.

An apparatus and method for eliminating mold lines when molding a part having ferromagnetic pigments is provided. A mold assembly having a mold with a cavity and valve gates is formed. Pucks are fitted at the gates to collect residual cold plastic. The calculation of a specific sequence and timing of the opening of the valve gates is determined based on a calculation of the total number of valve gates needed to fill a part while maintaining acceptable injection molding pressure. Once calculated, the gates are positioned around the mold cavity to balance flow length ratio. A primary gate is chosen for initial injection. The time for the material to flow from the first to the second gate is established. The second gate is opened after the flow front reaches the second gate. This pattern continues until all valve gates are opened.
