Abstract
An object of the invention is to provide a method for manufacturing a molded foam which is lightweight and excellent in strength. According to the invention, a method for manufacturing a molded foam from a foamed parison includes: an extruding step of extruding a resin blend containing a foaming agent and a thermoplastic resin to form a foamed parison; an attaching step of closely attaching facing portions of an inner wall surface of the foamed parison to each other to form a foamed parison laminated body; a mold clamping step of sealing and mold clamping the foamed parison laminated body by clamping the foamed parison laminated body by split mold blocks; and a sucking step of sucking air between the split mold blocks to reduce a pressure between the split mold blocks, after the attaching step and the mold clamping step.
