    摘要: Methods for manufacturing three-dimensional components of articles, including articles of footwear, apparel, and sporting equipment are provided. The disclosed methods comprise providing a first composition comprising a plurality of foam particles suspended in a liquid polymerizable composition, polymerizing a first portion of the liquid polymerizable composition to form a first layer of polymeric material at least partially encapsulating a first portion of the plurality of foam particles, repeating the polymerizing and forming for at least a second and third iteration, each iteration forming a layer on the previous layer, thereby forming a three-dimensional component having at least three layers, each layer including foam particles at least partially encapsulated by the first polymeric material. Articles manufactured using the disclosed methods are also provided.

    摘要: A method of forming a composite article includes constructing a preform having a strand layer including an interior portion and a peripheral portion surrounding the interior portion. The strand layer includes a plurality of strand segments traversing the interior portion and defining a first strand segment population density and a second strand segment population density. The preform is inserted into the mold cavity so that the interior portion of the preform is received in a molding region of the mold cavity. The molding region has a first thickness corresponding to the first strand segment population density and a second thickness corresponding to the second strand segment population density. Following the inserting, the mold is closed and the interior portion of the preform is compressed within the molding region. In the closed mold, the peripheral portion of the strand layer may be maintained in a loose state within the relief region.

    摘要: This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.
