Method for manufacturing laminate and apparatus for manufacturing same |
摘要 |
<p>A method for manufacturing a laminate includes steps of forming a laminated combination of synthetic resin sheet material with a metal foil laminated each other, thermoforming under a pressure the laminated combination while supplying an electric current to the metal foil, and, after termination of the current supply, cooling thus obtained laminate while further applying a pressure, whereby the laminated combination can be uniformly heated into its core part to allow the laminate of uniform quality to be obtained, while shortening manufacturing lead time and minimizing surface roughness. <IMAGE></p> |
