Abstract: The method employs a stationary mold having depositing recesses equipped in its inside with a deposition element such as a target electrode, and movable molds made slidable. A primary molding is performed to form a body portion and a cover member to have joint portions around their opening. The body portion left in the vertically sliding mold is deposited after it was densely covered with the depositing recesses. Next, the deposited body portion and the cover member, as left in the molds, are registered and mold clamped, and the molten metal is injected to integrated the joint portions.

Abstract: A molding apparatus is configured by a first, a second sliding die, a first, a second fixed die, and a sliding film forming chamber. The first, the second sliding dies are moved in directions reverse to each other to take a primary molding position, a film forming position and a secondary molding position. The sliding film forming chamber includes a first, a second masking plate and are arranged to be remote from the first, the second fixed dies. Further, the sliding film forming chamber is slid in an up and down direction. The first, the second sliding dies are respectively formed with recess portions and cores, the first, the second fixed dies are respectively formed with cores and recess portions.

Abstract: First and second semi-finished molded articles and a third semi-finished molded article are molded simultaneously so as to have joint end faces by using a slide die, a fixed die, and first and second slide cores fitted to the fixed die. The slide die with the third semi-finished molded article remaining thereon is moved toward the first and second slide cores, and their respective joint end faces are registered. Heating surfaces are inserted between the joint end faces. After melting the joint end faces, the heating surfaces are retracted, and the molding device is closed to weld the joint end faces.

Abstract: A pair of primary semi-hollow bodies formed by primary injection molding are united together by the molten resin injected for secondary injection molding to fill a joining space defined about the butt ends of the primary semi-hollow bodies having their open ends butted against each other. The molten resin for secondary molding fills the space between the butt ends, or the notch portion, too. Alternatively, the molten resin is compressed after filling the joining space and the space between the butt ends.

Abstract: A movable mold and a slide mold are employed. There is also employed a deposition apparatus which is equipped with a deposition element such as a target electrode in the inside of a depositing chamber. A body portion and a cover member are primarily molded by the movable mold and the slide mold. The molds are opened while the body portion being left in the movable mold and while cover member being left in slide mold. The body portion left in the movable mold is deposited in the molds with its inner surface being covered with the depositing chamber. Next, the slide mold is driven so that the cover member may be registered with the deposited body portion. Then, a secondary molding resin is injected to integrate the body portion and the cover member.

Abstract: Method and apparatus for manufacturing a synthetic resin-made hollow member incorporating an intermediate element are provided which enable operations of molding half bodies, abutting and joining the half bodies together, and molding an intermediate element in a series of steps, and which eliminate the necessity of such a manual work as may otherwise be required in incorporating the intermediate element into the half bodies. A pair of rotary injection molding dies are used which can be opened and closed relative to each other and are rotatable relative to each other over an angle of 60° for each turn, each die having a half body molding section including one male molding portion and two female molding portions in the direction of rotation for each rotational run over an angle of 120°, each die also having an intermediate element molding portion provided between specified half body molding portions in the direction of each rotational run over an angle of 120°.
