A portable structure or hunting blind includes a floor railing or frame system for supporting side walls and a roof. The side walls and roof are formed of polyurethane foam. The side walls and roof can be manufactured by applying uncured polyurethane foam over a sheeting material, which is supported by a removable set of forms. The polyurethane foam is then allowed to cure, and once cured the forms are removed. A door and windows and floor decking can then be installed to finish out the hunting blind. The exterior of the polyurethane foam walls and roof can be coated with an elastomer coating for UV protection.

A method of manufacturing a fluid control device includes extruding a polymer melt into a chamber defined by an outer surface of a support structure and a disintegrable metallic tubular member disposed at the support structure, the polymer melt comprising a high heat polymer and a foaming agent, the high heat polymer having a heat deflection temperature of about 100° C. to about 300° C. measured at 1.82 MPa in accordance with ASTM D648-18; sealing the chamber; and foaming the high heat polymer to produce a porous filtration medium in a compacted shape.

A method of manufacturing a headrest including a stay, a skin material, a cushion material, and a dynamic damper is provided. The method includes arranging the skin material in a molding die, arranging the stay, to which an air bag is attached in such a manner as to cover the dynamic damper, inside the skin material, and injecting a foamable synthetic resin raw material into the skin material to foam-mold the injected foamable synthetic resin raw material integrally with the stay.

Fabricate a panel (5) by building a sacrificial relief (10) by an additive process of multilayer deposition, applying a facade layer (20,30) over the sacrificial relief so as to conform to the contour of the sacrificial relief, depositing a foamable composition (40, 50, 60) over the facade layer.

The invention relates to a process for producing complex, mould-foamed rigid foam materials, more particularly of poly(meth)acrylimide (P(M)I) cores, preferably of polymethacrylimide (PMI) cores, which may be employed, for example, in carmaking or aircraft construction. A feature of the process is that through use of a particulate core during foam, it is possible to achieve an additional weight saving relative to foam materials or sandwich materials of the prior art.

A method for selectively producing a first or a second variant of a multi-layer plastic component, where both variants have a substrate part, a decorative layer, and a foam layer between the substrate part and the decorative layer, includes producing the foam layer in a foaming mold which has a first mold half, into which the substrate part is inserted before the foaming process. To produce the first variant, the decorative layer is inserted into a second mold half of the foaming mold before the foaming process. To produce the second variant, a spacer layer is inserted into the second mold half before the foaming process where, after the foaming process, the spacer layer is removed from the foam layer and the decorative layer is applied to the foam layer. The foam layer includes at least one first portion having a higher contour stability than a second portion.

A floral arrangement insert comprising: a foam insert; a plurality of tubes arranged and removably secured in the foam insert in a pre-designed configuration; and a plurality of artificial foliage inserted into the foam insert and around the plurality of tubes in a pre-designed configuration. A method of manufacturing a floral arrangement insert comprising: obtaining or preparing a mold; filling the mold with an expandable, curable foam to form a foam insert; inserting a plurality of tubes into the foam in a pre-designed configuration; causing or allowing the foam to cure after insertion of the plurality of tubes; and removing the foam insert from the mold after the foam has cured. The plurality of tubes can be filled with water and an artificial or fresh flower and/or foliage can be inserted into the plurality of tubes to create a beautiful floral piece.

The present disclosure discloses an anti-fatigue mat and methods for making the same. The method for making an anti-fatigue mat includes providing a leather comprising a first surface and a second surface opposite to the first surface, forming a color layer on the first surface, cutting the leather, putting the cut leather into a mold, injecting an elastomeric material into the mold, curing the elastomeric material to form an elastic layer on the second surface and a plurality of concave structures corresponding to the plurality of protruding structures on the first surface, and polishing the first surface to remove the color layer without caving towards the second surface. The anti-fatigue mat can have anti-fatigue performance and vivid stereoscopic impression, where being simple to fabricate with low costs and can be industrialized.

A method of forming wrapped components includes positioning an injection molded skin in a mold, forming a foam-in-place (FIP) foam substrate against the injection molded skin, removing the injection molded skin from the FIP foam substrate, bonding an external wrap to the FIP foam substrate, and reusing the injection molded polyolefin skin to form additional FIP foam substrates. A spacer layer may be bonded between and to the FIP foam substrate and the external wrap. The injection molded skin may be formed from a polyolefin polymer and may be a thermoplastic elastomer such as a thermoplastic vulcanizate. The FIP foam substrate may a FIP urethane foam substrate and the external wrap may be a leather wrap or a faux leather wrap. The injection molded skin reusable and may used a predetermined number of times, e.g., at least ten times, before being replaced by a replacement injection molded skin.

A headrest includes a stay, a skin material, a cushion material and a dynamic damper. The cushion material is foam-molded integrally with the stay inside the skin material, and has a hollow portion therein. The dynamic damper is attached to the stay, and is disposed in the hollow portion in such a manner as not to abut on the cushion material.
