METHOD AND APPARATUS FOR MANUFACTURING FOAMED RESIN METAL LAMINATED SHEET

摘要

When a foamed resin metal laminated sheet (1) heated in a heating furnace (11) is cooled to room temperature, the foamed resin metal laminated sheet (1) is held at soaking temperature in a soaking bath (21) to make the temperature of the foamed resin sheet uniform over the entire area of the foamed resin metal laminated sheet (1), and then cooled to room temperature in a room temperature cooling unit (22). Thus, rippling due to thermal strain can be suppressed.

主权项

1. A method for manufacturing a foamed resin metal laminated sheet, comprising:
a laminating step for laminating metal plates on both sides of a foamable resin sheet in an unfoamed state to form a foamable resin metal laminated sheet; a heating step for heating the foamable resin metal laminated sheet and foaming the foamable resin sheet to form a foamed resin metal laminated sheet; and a cooling step for cooling the foamed resin metal laminated sheet to room temperature, the cooling step comprising: a soaking step for cooling the foamed resin metal laminated sheet to a soaking temperature lower than a foaming temperature of the foamable resin sheet and higher than the room temperature, and holding the foamed resin metal laminated sheet at the soaking temperature; and a room temperature cooling step for cooling the foamed resin metal laminated sheet to the room temperature after the soaking step.
