    摘要: [Problem] The present invention relates to a manufacturing method for obtaining a molded article having an expanded layer in the molded article, wherein an expanding agent and device used to manufacture a resin having expansion properties, and a means for increasing expansion ratio are provided.[Solution] In the present invention, an expanding agent placed in a heating cylinder of a molding machine is configured as a liquid, the volume of the expanding agent is controlled, and the expanding agent is injected into a molten resin in the heating cylinder of the molding machine. The volume of the injected expanding agent can thereby be accurately measured each time. When a low-boiling liquid such as water, an alcohol, or an ether is used as the injected expanding agent, all of the liquid is vaporized by the temperature of the heating cylinder of the molding machine, and no residue thereof is therefore left in the molded article. When sodium bicarbonate water is used as the injected expanding agent, solvent water vaporizes and water vapor also becomes expandable gas, which is less expensive than using sodium bicarbonate as the expanding agent for a master batch using the resin that is to be molded.

    摘要: A mold apparatus and method is used to form a solid injection molded plastic part having no internal voids, a Class A finish, a sink-free exterior appearance surface, and unevenly distributed structural detail extending from the opposite surface, the detail including free-standing reinforcement ribs, attachment bosses, and the like. A charge of hot melted thermoplastic and pressurized gas are sequentially injected into a mold cavity defining the shape of the desired part, the plastic not filling the cavity and being simultaneously received in shaped recesses and grooves which form the structural detail. The pressurized gas forces the hot plastic from one mold half against the other mold half, and into the recesses and grooves, and is maintained during cooling. A gas seal is formed by the plastic to prevent gas in the mold cavity from reaching the finished exterior surface of the part during shrinkage of the plastic. Gas inlets and plastic volume areas cooperate with rib forming chambers to enhance resin distribution in the cavity. Importantly, the gas can be reclaimed, such as for recirculation and cooling.

    摘要: A center-portion molding member having a center-portion transfer shape surface and a side wall surface is inserted and fitted in a frame-portion molding member having a frame-portion transfer shape surface to form a part of a cavity. The center-portion molding member has a groove portion in the side wall surface. The groove portion protrudes from the frame-portion transfer shape surface. Before injected resin transfers a shape of the center-portion transfer shape surface, the side wall surface of the center-portion molding member is sealed with the resin to form, between the center-portion transfer shape surface and the resin, a space in which gas is confined.

    摘要: To cause uniform infiltration in a thermoplastic resin surface in a short time using a small amount of a surface reforming material. A surface reforming method of a thermoplastic resin includes a step of opening a movable mold after a thermoplastic resin is molded in a cavity to form a gap between a portion of a molded product and a stationary mold, a step of introducing supercritical fluid, subcritical fluid, or high pressure gas including a surface reforming material into the gap, a step of narrowing the gap by closing the movable mold by a predetermined amount to prevent leaking of the introduced supercritical fluid, subcritical fluid, or high pressure gas from the gap, and of charging the supercritical fluid, the subcritical fluid, or the high pressure gas into a narrowed second gap, and a step of clamping and compressing the molded product.
