Methods for forming carbon-based cellular structures and 3D structures that can be formed by use of the methods are described. Methods include shaping an essentially 2D sheet that includes an organic polymer to form a 3D precursor followed by heat treatment of the 3D precursor. Heat treatment carbonizes the polymer to form an amorphous carbon. A metal precursor solution can be applied to the 3D precursor, and subsequent heat treatment can form a metal carbide, metal nanoparticles, or other carbon-based materials on/in the cellular structures.

A disclosed sizing roller apparatus for a folding process of a battery cell includes: a table fixing and supporting a battery cell; a base plate disposed on a side of the table; a plurality of sizing rollers disposed on the base plate and each having a rotation axis, which is inclined inward toward a folding portion of the battery cell, to press the folding portion of the battery cell in contact with the folding portion; and a plurality of air spray nozzles disposed on the base plate and spraying air to the plurality of sizing rollers.

There is disclosed a mould for forming a collapsible container from an expandable material, the container comprising, when assembled, at least a base and a two pairs of a side walls extending at right angles from opposing sides of the base, the mould comprising: a first mould member and a second mould member movable with respect to each other between an open and a closed moulding position to define a mould cavity; a control means for delivering expandable material into said mould cavity and for delivering steam to facilitate expansion of the expandable material within said mould cavity to form said container; and a plurality of anvils mounted on a rear surface of at least one of the first mould member and/or second mould member, each anvil being movable so as to be extended into the mould cavity so as to form one or more hinges in the expandable material at predetermined locations within the mould cavity; wherein the mould cavity defined by the first mould member and the second mould member is a three-dimensional representation of an inside-out configuration of the assembled container.

A method for manufacturing a liner, in particular for the cabinet of a refrigerator, allowing to leave out a deep thermoforming step. The method includes extruding a sheet, trimming the sheet, folding the sheet and joining adjacent edges of the sheet.

A method for creating a flexible portion or bending portion within a rigid structure. The method can also be used for creating a flexible structure from a rigid material. The method includes providing a substantially rigid material, such as, but not limited to, metals, alloys, hard plastics, and the like, and selectively removing portions of the rigid material defining a geometric pattern in the rigid material. A bending radius of the flexible portion is defined by the geometric pattern. The rigid structure may be used to create an enclosure, a cover for an electronic device, one or more hinges, or the like.

A beverage vending machine with a stirrer dispenser configured to form and dispense disposable stirrers from a strip made of food-grade material, preferably biodegradable or compostable and preferably plastic-free and waterproof. The stirrer dispenser comprises a detaching device configured either to detach, or to allow manual detachment of, an end piece of the strip with such a length as to be usable as a stirrer.

The present disclosure provides a display motherboard and a method for manufacturing the same, a display substrate and a method for manufacturing the same, and a display device, and belongs to the field of display technology. In the method for manufacturing the display motherboard of the present disclosure, the display motherboard includes a plurality of display substrate areas each including a sub display area and a sub bending area; and the method for manufacturing the display motherboard includes: forming an adhesive force variable back film material having a first adhesive force on a flexible underlying substrate; removing the back film material in positions above the sub bending areas; and treating the remaining back film material to form a back film having a second adhesive force, wherein the second adhesive force is greater than the first adhesive force.

A blank for a box made from an expandable material, which is initially molded to be substantially flat and in which folds forming hinges are to be made to enable the formation of the box. The tooling defines the shape of the blank is such as to provide a thickness of the expanded material that is less than the thickness of a major portion of the blank, in which folds are to be made having defined edges, generally in the direction of each fold; the fold and subsequently applying pressure along an area where folds are to be permitted to reduce the blank are made without removing material therefrom for providing hinges to permit formation of the box. A related method for making the blank and a box that is made from the blank are further provided.

A reusable plastic container is provided. The container includes a plastic container body having opposing side panels and opposing end panels. The container body also includes top side panel flaps attached to a top portion of each side panel, and bottom side panel flaps attached to a bottom portion of each side panel. The container body has top end panel flaps attached to a top portion of each end panel, and bottom end panel flaps attached to a bottom portion of each end panel. The top and bottom side panel flaps are each defined with respect to the side panels by a fold line. The fold lines including at least one scored portion and at least one welded portion.

A duct that, in cross section, has one or more rounded portions is disclosed together with a method and a machine for producing it. The duct can be made from rigid foam panels with a facing on at east one side of the panels. A crimping element is used to form several substantially parallel indentations or crimps on a faced side of a panel, without breaching the facing, so that the crimped panel can be manipulated to form a section of duct with the crimps extending longitudinally. Depending on the number of crimps, the duct will appear more or less round in cross section although the crimped foam panels can be manipulated to have cross sections of different shapes such as oval. Adjacent duct sections may be joined, for example, with tape or bands, several of which are described.
