Abstract

PURPOSE: To perform a trial of the mold by a method wherein a special foam mixing liquid is poured into the mold and reactioned therein, thereafter a polyurethane formed product is released from the mold, a pouring of the mixing liquid into the mold may be performed under a low pressure, thereby the mold may easily be released.
CONSTITUTION: When the trial for the mold is performed in order to check a finish of a shape of the mold after its completion of manufacturing, a mixing liquid having major constituent of diisothyanate and polyohl and further having a catalyst and foaming agent therein is poured into the mold, and a polyurethane is synthesized in the mold. Upon completion of a reaction, the formed product is released from the mold, and a shape of the mold is checked in reference to the formed product.
