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.

A bushing for a foam mix-head includes an injection port wall surrounding a vestigial area for foam accumulation, a substrate opening transition segment configured to be situated with an opening of a substrate, a seal housing, and a seal seated in a seal seat of the seal housing. The seal helps prevent leakage during a foaming operation, such as when manufacturing a vehicle interior panel having a foam layer between a skin layer and a substrate.

A method and device for manufacturing a sandwich structure comprising at least one foam layer of a first thermoplastic comprising a chemical blowing agent and two cover layers. The decomposition temperature of the chemical blowing agent is higher than the melting point or range of the first thermoplastic. The method comprises a series of steps performed on an advancing starting structure including heating under pressure in order to cause decomposition of the blowing agent, intermediate cooling, foaming at a constant volume and further cooling.

A mold for in-mold foam molding of polyolefin-based resin that prevents the occurrence of burrs at the time of molding to control productivity reduction and labor cost rising caused by burr trimming. A mold is configured to mold an insert member including an embedded part to be embedded into a foaming molded body formed from a polyolefin-based resin and a protrusion part protruding from the foaming molded body integrally with the foaming molded body. The mold is provided with an accommodation concave part capable of accommodating the protrusion part and an opening/closing part capable of opening and closing a cavity-side opening in conjunction with insertion and extraction of the protrusion part into and from the accommodation concave part such that, while the protrusion part is inserted into the accommodation concave part, and the cavity-side opening is closed.

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 and device for manufacturing a sandwich structure comprising at least one foam layer of a first thermoplastic comprising a chemical blowing agent and two fibre-reinforced cover layers of a second thermoplastic. The decomposition temperature of the chemical blowing agent is higher than the melting point or range of the first thermoplastic. The method comprises a series of steps performed on a starting structure including heating under pressure in order to cause decomposition of the blowing agent, cooling, foaming and further cooling in contact with the press tools.

A molded foam member manufacturing method including: a first process of placing a foam molded first portion and a rigid member in a second portion forming mold, and pressing and fixing the rigid member against the second portion forming mold; and a second process of pouring a second portion-forming synthetic resin raw material into the second portion forming mold and foam molding a second portion so as to surround at least a portion of the rigid member and to form an integral unit with the first portion.

A refrigeration apparatus and a production method thereof. The refrigeration apparatus includes a silencing device. The silencing device includes a silencing channel, and the silencing channel is communicated with an inner vent of a compressor bin and an outer vent of a housing. The silencing device is provided in a foaming space and thus does not occupy a space inside the refrigeration apparatus. The compressor bin is connected with the outside through the silencing channel, thus reducing noise radiated outwards from the compressor bin.

A member (10) for providing sealing, baffling, and/or reinforcement to a cavity member (30) comprising: (a) a carrier (12) with an insertion end (13) and a base end (11) having: (i) a base (16) at the base end (11) adapted for engaging with a wall (36) of the cavity member (30); (ii) a fastener (20) adapted for passing through an opening of the cavity member (32) and retaining the member (10) to the cavity member (30); (iii) a center portion (18) extending from the insertion end (13) to the base end (11); and (b) activatable material (26) disposed on the carrier (12).

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.
