Abstract
PURPOSE: To produce a synthetic wood having a natural and uneven surface in an easy release method by pouring an expendable resin composition into the mold having a flat molding surface partially at unequal temperatures and by freely expanding all over the resin after it has been partially expanded.
CONSTITUTION: Portions of a flat moding surface 4 inside a bottom mold 5 are divided by an insulation material 6 for pouring an expandable resin composition therein. This bottom mold 5 is, then, heated in such a manner that the temperature of the molding surface partially becomes unequal and, after the expandable resin composition is partially foamed, it is taken out of the bottom mold 5. After that, this semi-finished product that has been partially expanded is heated all over without any restriction in order that the nonexpanded portions thereof are completely foamed and cured. This molded product is, therefore, made up of a flat, expanded portion 7 that has been foamed inside the mold and an expanded portion 8 having a natural and uneven surface 9 due to the expansion in a non-restrictive condition.
