<p><P>PROBLEM TO BE SOLVED: To eliminate defect due to presence of air during thermal compressing in a resinified portion when resinifying an urethan foam by thermally compressing to cause permanent strain. <P>SOLUTION: In the method in which the portion is resinified by thermally compressing a part or whole of the soft urethan foam to cause permanent strain, in the compressing molding method of the urethan foam in which the urethan foam is resinified by compressing the portion to be resinified from both faces by molding mold and heating the portion to be compressed under reduced pressure, a highly compressed portion and lowly compressed portion can be compatibly present in the resinified portion. Molding molds:5, 6, a chamber:7, the urethan foam:1, a dent:5b, a mountain portion:6b, a step portion:D, gaps between both molds:S1, S2, vacuum:Q. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
