发明名称 FOAMED BODY AND METHOD FOR MOLDING THE SAME
摘要 PURPOSE:To easily mold a foamed body enhanced in impact strength by providing a thick skin layer to the foamed body from the other surface thereof. CONSTITUTION:In an extrusion foam-molded body having a foam layer therein and a skin layer on the outer surface thereof, a foamed body has a skin layer thicker than the skin layer on the other outer surface thereof. By differentiating the cooling temps. of outer surface resin layers at the time of the passage through a foaming die 2, a thick skin layer 31 is formed to one surface of the foamed body and the surface having the thick skin layer 31 formed thereto is sucked under vacuum at the time of the passage through the foaming die 2.
