摘要： After heating the expandable resin beads to sealing temperature of expandable resin beads in the presence of heated steam, foam cells are sealed and cooled while controlling the foaming amount. Preferably, the foaming amount is controlled by pressure control on the expandable resin beads in the mold. Mutually adjacent foam cells are softened, fused, and bonded on contact faces, and thereby a foamed molding is manufactured. This foamed molding is characterized by three-dimensional permeable pores of volume porosity of 10 to 40% among foam cells, having bending limit strength of at least 10N. Without using adhesive resin, a foamed molding having enough strength and desired porous structure is obtained.
