METHODS OF MANUFACTURING AN ARTICLE OF FOOTWEAR INCLUDING SINTERING A COPOLYMER POWDER

摘要

A method of manufacturing an article of footwear includes providing a powder including a plurality of particles each comprising ethylene vinyl acetate, delivering the powder to a cavity of a mold, the mold being at an elevated temperature, pressing the powder in the cavity of the mold between the mold and a counter-mold, the counter-mold being at an elevated temperature, to fuse the particles of the powder and thereby provide a first portion of the article of footwear, removing the first portion of the article of footwear from the cavity of the mold, cooling the first portion of the article of footwear, providing a second portion of the article of footwear, and coupling the first portion of the article of footwear to the second portion of the article of footwear.
