A panel assembly that includes at least a first upper base layer made of a thermoplastic material that includes fibers therein, at least a first lower base layer made of a thermoplastic material that includes fibers therein, and at least a first reinforcement layer sandwiched or positioned between the first upper base layer and first lower base layer. The upper and lower surfaces of the first reinforcement layer have a smaller surface area than the upper and lower surfaces of the first upper and first lower base layers. The lower surface of the first upper base layer is welded to the upper surface of the first reinforcement layer, and the lower surface of the first reinforcement layer is welded to the upper surface of the first lower base layer.

A method of making a molded plastic arch shape cross section stormwater chamber having a corrugated wall comprises molding half chambers which are connected by hinges at a joint at the top of the chamber. The chambers may be compactly stored and transported in splayed out configuration. Later, upward force is applied to the hinge joint location of each chamber, so the half chambers are rotated by force of gravity, whereby a faying surface on each half chamber is urged toward the like surface of the other half chamber. The faying surfaces are then fused to each other, preferably as a result of prior heating or by melting of a fusion weld element that is captured in the space between the faying surfaces.

A vacuum insulated structure includes a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers or elastomeric or hybrid material systems. The multi-layer sheet of material is thermoformed or vacuum formed to form a non-planar first component having a central portion and four sidewalls extending transversely from the central portion. A second component having a central portion and four sidewalls extending transversely from the central portion is secured to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space by removing gasses and moisture (water vapor). The first and second components are sealed together to form a vacuum insulated structure.

A process for making a hermetically sealed package, which includes forming a sheet of wrapping made of plastic material, in particular having a thickness of less than or equal to 140 m. The process envisages: forming on the sheet a first, hollow, portion and a second, perimetral, portion, which delimits at least partially the first portion; inserting the product into the hollow portion obtained in the sheet of wrapping; applying a second sheet of wrapping in contact with the perimetral portion so as to close the hollow portion with the product inside; and welding the second sheet on the first sheet along the perimetral portion. Forming the first sheet includes providing on the second, perimetral, portion a series of pleats of the sheet, which are then sealed.

A layered sheet product formed by layering a plurality of cloths comprised of thermoplastic resin strands and formed by layering a coating layer comprised of a thermoplastic resin onto at least one surface of the cloths, in which the thermoplastic resin is comprised of the same component as the strands and has a thickness of 0.02 mm or more and 1.0 mm or less, and a storage modulus of the coating layer at 150? C. is 3.00?106 Pa or higher and 1.00?108 Pa or lower, and a method for press molding the layered sheet and releasing the molded product after cooling to a range of 70? C. or more and 120? C. or less; and subsequently lowering the molded product temperature to 60? C. or lower.

A method for forming cellulose products in a mould system from an air-formed cellulose blank structure, where the forming mould system comprises a first mould part and a second mould part. The method comprises the steps: providing the cellulose blank structure, and defining one or more product sections and a residual section; compressing at least a portion of the residual section to a first degree of compression higher than a degree of compression of the one or more product sections; feeding the cellulose blank structure in a feeding direction to a forming position in the forming mould system, where in the forming position each product section is arranged between a corresponding first mould part and second mould part; forming the cellulose products from the cellulose blank structure between the first mould part and the second mould part by heating the cellulose blank structure and pressing the cellulose blank structure.

A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100? C. to 200? C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

C. to 200? C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.

A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A mold tool includes: a first tool part and a second tool part that works together with the first tool part. In the closed state, the two tool parts are moved toward one another, and in the open state, the two tool parts are moved away from one another. The mold tool also includes a first mold half in the first tool part and a second mold half in the second tool part. The two mold halves reshape the sheet of material, arranged between the two tool parts, into at least one three-dimensional article when the two tool parts are moved toward one another. The mold tool also includes a cutting device including at least one cutting element and at least one actuating device. The actuating device extends the cutting element in the direction of the sheet of material, to cut the sheet of material.
