PURPOSE:To prevent cracks or the like from developing, even when the mold temperature is low, and realize a coated molded part, the coat of which does not peel off for a long time, by a method wherein molding is performed under the condition that composite plating film consisting in eutectic dispersing fluoropolymeric material is formed onto the surface of a cavity and, in addition, coating is applied onto the necessary surface. CONSTITUTION:The formation of composite plating film consisting in eutectic dispersing fluoropolymeric material onto the surface of a cavity gives excellent heat insulating or retaining effect to a mold. Consequently, even with no extra heat retaining of the mold, the cooling rate of a molded part is made slower, resulting in preferably preventing thermal stress from generating in the molded part and enabling to mold the favorable engineering plastic molded part with no crack or the like. Further, because the molded part has excellent adhesion of coating, the obtained molded part with coated area is satisfactorily used for a long time with no peeling of the coat. The amount of fluoropolymeric material in the composite plating film is especially set to be 15-40wt%. In addition, the thickness of the plating film is preferably set to be 5-30mum. |
