Abstract

PURPOSE:To obtain favorable quality in an external appearance under coating condition of 80 deg.C or higher, by a method wherein a split mold where the backside for a product has been formed of a mold material having better heat insulating properties than that of a surface side is heated at a temperature in the vicinity of the glass transition temperature or higher and the product is held for a predetermined period of time within the mold after a backside mold temperature has been raised to the temperature in the vicinity of the glass transition temperature or higher within the mold after molding. CONSTITUTION:A split mold for the backside of a product is formed of mold material having better heat insulating properties than that of a mold 3 for a surface side or in mold dimensions therefore. When the molds 3, 4 are heated at a temperature in the vicinity of the glass transition temperature or higher, reaction injection molding of the mold 3 for the surface side of the product is performed under a state where a temperature of the mold 3 is higher than the mold temperature of the backside of the product. As the heat insulation properties of the mold 4 for the backside of the product is higher than those of the mold 3 for the surface side of the product, a temperature of the backside of the product raised due to reaction heat falls gradually and the product is held at 80 deg.C or higher for a long period of time. In other wards, the product is kept at the temperature in the vicinity of the glass transition temperature or higher while the product is held within the split mold, internal stress on the backside of the product is eliminated, the product does not deform even if coating or drying or baking or curing is performed at the temperature of 80 deg.C or higher and favorable quality in an external appearance is obtained.
