A method for mounting a preformed seal on a substrate comprises the steps of providing the preformed seal at a predetermined position relative to the substrate, at least a part of the preformed seal being spaced at a distance from the substrate; arranging a mold in contact with the substrate and the preformed seal, wherein the mold holds the preformed seal at the predetermined position and wherein the mold, the substrate and the preformed seal delimit a mold cavity. Further, the method comprises at least partially filling the mold cavity with a solidifiable composition, wherein the solidifiable composition is in contact with the substrate and the preformed seal bridging the distance; and solidifying the solidifiable composition, whereby the solidifiable composition forms a molded part adhering to the preformed seal and to the substrate. The preformed seal and the solidifiable composition are configured to adhere to each other.

A molding device and an injection molding method thereof are provided. The molding device includes a first mold, a second mold and a sealing ring. The first mold includes a first body and at least one slide. The at least one slide is movably and detachably disposed on the first body, and has an undercut. The injection molding method includes operations of: engaging the first mold with the second mold of the molding device; filling a mold cavity defined by the first mold and the second mold with a gas, wherein the gas is blocked by the sealing ring disposed between the first mold and the second mold; injecting a molding material into the mold cavity; and opening the first mold and the second mold of the molding device.

A rotary core includes an undercut portion molding section for molding an undercut portion in a resin-molded article, and a seal portion abutting on a mold main body. In a side view viewed from a direction orthogonal to the direction in which a shaft member serving as the rotation center of the rotary core extends, a first imaginary line extending along the inner edge of the seal portion, and a second imaginary line extending from the rotation center to the first imaginary line and orthogonal to the first imaginary line are drawn. The seal portion includes a portion that is located on a lower side of the second imaginary line and is bent inward in the width direction as compared with a portion of the seal portion that is located on an upper side of the second imaginary line.

A mold for casting a polymeric aircraft window panel includes a first mold half having a first mold surface, and a second mold half having a second mold surface. The first mold surface and/or the second mold surface have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half and/or the second mold half can be formed of rolled, hydroformed, or stamped metal.

A rotary core includes an undercut portion molding section for molding an undercut portion in a resin-molded article, and a seal portion abutting on a mold main body. In a side view viewed from a direction orthogonal to the direction in which a shaft member serving as the rotation center of the rotary core extends, a first imaginary line extending along the inner edge of the seal portion, and a second imaginary line extending from the rotation center to the first imaginary line and orthogonal to the first imaginary line are drawn. The seal portion includes a portion that is located on a lower side of the second imaginary line and is bent inward in the width direction as compared with a portion of the seal portion that is located on an upper side of the second imaginary line.

A method for forming a seal between structural components includes placing a retainer flap on a first side of a first structural component over a first channel within the first structural component and over a second channel within the first structural component such that the retainer flap, the first side of the first structural component, and a second structural component form a cavity. The first channel extends between the first side of the first structural component and a second side of the first structural component that is opposite the first side. The second channel extends between the first side of the first structural component and the second side of the first structural component. The method also includes evacuating the cavity through the first channel, thereby forcing the retainer flap against the second structural component and forcing a sealant to flow through the second channel into the cavity.

A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the sealing step, the conductive members are sealed with a resin injected into a die while a force is applied by the resin to the individual conductive members in directions to approach each other in a facing orientation of the pair of conductive members.

A mold die includes a resin injection gate through which fluid resin serving as mold resin is injected toward a cavity, a resin reservoir to store the fluid resin flowing through the cavity, and a resin reservoir gate. The resin reservoir is provided on the side opposite to the side on which the resin injection gate is arranged with the cavity interposed. The resin reservoir gate communicatively connects the cavity and the resin reservoir. The opening cross-sectional area of the resin reservoir gate is smaller than the opening cross-sectional area of the resin injection gate.

A method for forming a seal between structural components includes placing a retainer flap on a first side of a first structural component over a first channel within the first structural component and over a second channel within the first structural component such that the retainer flap, the first side of the first structural component, and a second structural component form a cavity. The first channel extends between the first side of the first structural component and a second side of the first structural component that is opposite the first side. The second channel extends between the first side of the first structural component and the second side of the first structural component. The method also includes evacuating the cavity through the first channel, thereby forcing the retainer flap against the second structural component and forcing a sealant to flow through the second channel into the cavity.

A mold for casting a polymeric aircraft window panel includes a first mold half (12) having a first mold surface (24), and a second mold half (14) having a second mold surface (50). The first mold surface (24) and/or the second mold surface (50) have a shape conforming to a final shape for the major surfaces of the aircraft window panel. The first mold half (12) and/or the second mold half (14) can be formed of rolled, hydroformed, or stamped metal.
