Abstract

PURPOSE: To release a residual stress quickly and completely, by heating rapidly only a resin part holding an insert in a molded-in insert article above the softening point of the resin.
CONSTITUTION: The resin part 2 which holds the insert member 1 in the molded-in insert article 10 molded by infection molding is heated above the softening point of the resin, by bringing it into contact with the heating plate 3 having the heater 4 or by blowing hot air on it, thus releasing a residual strain in the resin part 2.
