SYSTEMS AND METHODS FOR MANUFACTURING A PORTION OF AN ARTICLE OF FOOTWEAR FROM A MOLD

A method for manufacturing a sole assembly of an article of footwear includes injecting a first material into a first mold to forming a first component. A second material is injected into a second mold to form a second component in the second mold. The first component is formed from a first material and includes a first plurality of channel elements. The second component is formed from a second material and includes a second plurality of channel elements. Each of the first plurality of channel elements is aligned with a corresponding one of the second plurality of channel elements, and the first component is secured to the second component to form an initial sole assembly.

Articles and methods of making articles including a coating
11647809 · 2023-05-16 · ·

The present disclosure is directed to articles that include a cured coating that includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating can include a matrix of crosslinked polymers. The cured coating is a product of crosslinking a coating composition comprising uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier to form the matrix of crosslinked polymers), wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers. The matrix of crosslinked polymers can be elastomeric. The present disclosure is also directed to articles including these bladders, methods of forming these bladders, and methods of making articles including these bladders, where the bladders include the cured coating.

CORED MIDSOLE WITH DIAGONAL GEOMETRY

A sole for an article of footwear includes a cored midsole defining a top surface, a bottom surface, and a perimeter surface extending from the top surface to the bottom surface. The cored midsole defines apertures extending diagonally from the top surface of the cored midsole to the bottom surface of the cored midsole.

Roofing membranes, compositions, and methods of making the same

A roofing membrane and a method of making the same is provided. The roofing membrane includes a top layer having a flame retardant and a first silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3; a scrim layer; and a bottom layer having a flame retardant and a second silane-crosslinked polyolefin elastomer with a density less than 0.90 g/cm.sup.3. The top and bottom layers of the roofing membrane both exhibit a compression set of from about 5.0% to about 35.0%, as measured according to ASTM D 395 (22 hrs @ 70° C.).

A method of using a marriage mold includes providing an upper plate having a first wall and at least one second wall, and a lower plate having a marriage cavity and a top wall. At least two midsole components are provided, which are made of a first material, and each have a first region and a void structure. The at least two midsole components are positioned into the marriage cavity. The upper plate is secured to the lower plate such that the first wall and the top wall form a seal. The at least two midsole components are joined together to form a midsole having a second void structure.

ECO-FRIENDLY METHOD OF MANUFACTURING SHOE MATERIAL, SEMI-FINISHED, AND FOAMED SHOE MATERIAL MADE THEREBY
20230189924 · 2023-06-22 · ·

A method of manufacturing the foamed shoe material and semi-finished product including the following steps. Step S1: a foamable material is injected into a cavity of a blank mold to solidify, thereby generating a semi-finished product of the shoe material and a runner waste that are unfoamed. The runner waste could be shed for reusing directly as the foamable material without a granulating process. Step S2: the semi-finished product is cooled down and put into a cavity of the foaming mold, and the semi-finished product is evenly foamed in the cavity of the foaming mold to obtain a shoe material wherein the waste generated during the method of manufacturing the foamed shoe material could be effectively reused, and the yield rate of the shoe material thereby enhanced.
