A molding tool and method for producing an interior trim part. A cavity is embodied between a first element and a second element, and a slide is displaceably connected to the first element. A decorative layer is arranged on the first element and a backing is arranged on the second element. A foamable mixture is added to the hollow area between the backing and a reverse side of the decorative layer, such that a foam layer fills the hollow area. A distance between the first element and the second element is increased to enlarge the hollow area. During this process, the slide is pressed against a side facing away from the reverse side of the decorative layer, such that the hollow area is sealed with the reverse side of the decorative layer pressed against a lateral surface of the backing and/or against a lateral surface of the second element.

This invention relates to a method for manufacturing a polyurethane concrete sandwich component. The inventive method, keeping the transformation of the production flows of the present technology to the minimum, can rapidly form a seamless insulating layer system. The inventive method can prevent the condensation of water vapor between the seams of the insulating board, avoid water percolation and leakage of the walls after the building is finished, and avoid the corrosion of connecting elements and connecting steel bars due to moisture attacks. This invention also relates to a polyurethane concrete sandwich component, which is prepared from the method according to the present invention.

An apparatus and method for manufacturing a pipe assembly having an inner pipe and an outer jacket may include a support member, a pair of lance assemblies and a pair of caps. The support member supports the outer jacket of the pipe assembly and is drivable between a first position and a second position. The pair of lance assemblies are configured to be inserted into opposing ends of the inner pipe such that the pair of lance assemblies engage an inner wall of the inner pipe. One of the outer jacket and the inner pipes moves relative to the other of the outer jacket and the inner pipe to center the inner pipe within the outer jacket when the support member is driven from the first position to the second position. Insulation is inserted through at least one cap into a space between the inner pipe and outer jacket.

A method for manufacturing a seat cushion material, the seat cushion material including a front layer part and a back layer part having a back side surface, the method including: preparing for molding the seat cushion by attaching the back layer part to an upper die having an upper cavity surface; molding the seat cushion material by adding foamed resin raw material forming on a lower cavity surface of a lower die and then by closing the upper die to which the back layer part is attached, the lower cavity surface being provided with a plurality of protrusions which is configured to be brought into contact with a seating surface side of the back layer part and press the back layer part against the upper cavity surface when the upper die to which the back layer part is attached is closed; and demolding the molded seat cushion material.

A molding method of a resin molded product in which it is possible to increase the welding strength between the core member and the resin sheets. In a molding method of a resin molded product in which a core member including a foaming element is interposed between at least two resin sheets in a melted state into a laminated product, wherein the resin sheets include fibrous filler, and while melting surfaces of the core member by heat of the resin sheets, the core member and the resin sheets are welded onto each other, and the core member and the resin sheets are clamped by a metallic mold, to mold the resin molded product.

A method of forming a fin configured for use with a water sports board. The method includes providing a mold having a mold cavity and a first insert pre-preg sheet each including structural strands bonded by a first resin material. The method further includes placing the first insert pre-preg sheet within the mold cavity. The method further includes injecting a third resin material under pressure into the mold cavity. The method further includes injecting a core substance only in the form of a gaseous material into the third resin material to form a unitary hollow volume within the third resin material.

Provided are a vehicle seat member in which even when a foamed resin molded body forming the vehicle seat member shrinks after being demolded, influence of the shrinkage behavior on a frame member embedded in the foamed resin molded body can be prevented, and thus a change in the position of a protrusion, which serves as a part to be anchored to a vehicle body, of the frame member can be prevented, whereby the vehicle seat member can be attached to the vehicle body side easily and reliably, and a vehicle seat including such a vehicle seat member. A vehicle seat member includes a foamed resin molded body and a frame member integrally formed therewith, the frame member including a body portion embedded in the foamed resin molded body and protrusions each protruding from the body portion and having a tip end protruding outward from the foamed resin molded body.

A manufacturing method for a conveyance seat having a pad structure including a seat pad and a back face member includes integrally molding the seat pad with the back face member in a state where the back face member is arranged so as to cross over at least part of a parting line that is formed by laying a first sub element and a second sub element of a molding die on top of each other, the molding die being formed of at least the first sub element and the second sub element.

A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.
