Method and apparatus for recycling metal sheet-thermoplastic resin laminate composites

摘要

Metal sheet-thermoplastic resin laminate composites may be effectively separated into their component metal sheet(s) and thermoplastic resin sheet or core by first pressing the laminate composite through a pair of opposing rollers in which the roller(s) making contact with the metal surface(s) of the laminate composite is an embossing roller having projecting pins to obtain a laminate composite having a metal surface(s) with impressions and then heating the metal surface(s) of the laminate composite to separate the metal sheet(s) from the thermoplastic resin.
