发明名称 Method for manufacturing E.V.A. foamed sports equipment
摘要 A method for manufacturing an E.V.A. foamed sports equipment includes preparing and stirring an E.V.A. foamable mixture, then integrally forming the foamable mixture into a sports equipment blank with a constantly reduced scale, the constantly reduced scaled sports equipment blank being placed in a reduced scaled heat forming mold to be heated at the temperature of 180° C., then opening the reduced scaled heat forming mold after a pre-determined period of time, the constantly reduced scaled sports equipment blank in contact with the air being expanded into a foamed sports equipment blank, then, placing the foamed sports equipment blank and ornamental strips into a constantly scaled pattern generating mold to be heat pressed and melted into a unity, the generating mold being evacuated so that the periphery of the foamed sports equipment blank is attached to the pattern generating mold so as to form a foamed sports equipment product with a precise knurl pattern being formed thereon.
