A manufacturing method of a sports ball, comprising the steps of: forming a cover of the sports ball, comprising: a. cutting outer layer cutouts (310, 402, 404) from an outer layer (100, 200, 300) for a plurality of panels, the outer layer (100, 200, 300) consisting at least of a fabric and one of ethylene propylene diene monomer (EPDM) foam (106, 206), Ethylene Vinyl Acteate, or synthetic leather; b. creating a valve panel by inserting a valve in one of the outer layer cutouts (310, 402, 404); c. determining attachment lines (410, 412, 414, 416) on each of the outer layer cutouts (310, 402, 404), the attachments lines (410, 412, 414, 416) at a distance of 2 to 6 mm from edges of each of the outer layer cutouts (310, 402, 404); d. connecting the outer layer cutouts (310, 402, 404) together using machine stitching or using glue at the attachment lines (410, 412, 414, 416); e. inverting the cover inside out so that respective inner surfaces of the outer layer cutouts (310, 402, 404) are within the cover; and f. hand stitching or applying glue to any remaining unattached attachment lines (410, 412, 414, 416); placing the cover in a mold; forming a solid cellular foam within the cover by inserting a plurality of liquids through the valve, the plurality of liquids comprising of polyol polyether and isocyanates; and solidifying shape of the cover and the foam by applying heat to the cover in the mold. forming a cover of the sports ball, comprising: a. cutting outer layer cutouts (310, 402, 404) from an outer layer (100, 200, 300) for a plurality of panels, the outer layer (100, 200, 300) consisting at least of a fabric and one of ethylene propylene diene monomer (EPDM) foam (106, 206), Ethylene Vinyl Acteate, or synthetic leather; b. creating a valve panel by inserting a valve in one of the outer layer cutouts (310, 402, 404); c. determining attachment lines (410, 412, 414, 416) on each of the outer layer cutouts (310, 402, 404), the attachments lines (410, 412, 414, 416) at a distance of 2 to 6 mm from edges of each of the outer layer cutouts (310, 402, 404); d. connecting the outer layer cutouts (310, 402, 404) together using machine stitching or using glue at the attachment lines (410, 412, 414, 416); e. inverting the cover inside out so that respective inner surfaces of the outer layer cutouts (310, 402, 404) are within the cover; and f. hand stitching or applying glue to any remaining unattached attachment lines (410, 412, 414, 416); a. cutting outer layer cutouts (310, 402, 404) from an outer layer (100, 200, 300) for a plurality of panels, the outer layer (100, 200, 300) consisting at least of a fabric and one of ethylene propylene diene monomer (EPDM) foam (106, 206), Ethylene Vinyl Acteate, or synthetic leather; b. creating a valve panel by inserting a valve in one of the outer layer cutouts (310, 402, 404); c. determining attachment lines (410, 412, 414, 416) on each of the outer layer cutouts (310, 402, 404), the attachments lines (410, 412, 414, 416) at a distance of 2 to 6 mm from edges of each of the outer layer cutouts (310, 402, 404); d. connecting the outer layer cutouts (310, 402, 404) together using machine stitching or using glue at the attachment lines (410, 412, 414, 416); e. inverting the cover inside out so that respective inner surfaces of the outer layer cutouts (310, 402, 404) are within the cover; and f. hand stitching or applying glue to any remaining unattached attachment lines (410, 412, 414, 416); placing the cover in a mold; forming a solid cellular foam within the cover by inserting a plurality of liquids through the valve, the plurality of liquids comprising of polyol polyether and isocyanates; and solidifying shape of the cover and the foam by applying heat to the cover in the mold.
