Abstract
A molded product which is free of flash resulting from application of a coating agent or the like, parting surface covering masks for preventing the flash, and producing methods of these. The mask is mounted to each of a lower mold and an upper mold, so as to cover parting surfaces which are at inner side than a rim molding portion and cover their vicinities. Adjusting portions are attached to a mask body of the mask, and are capable of correspondingly getting tight contact with the parting surfaces. Accordingly, even when the coating agent is applied to the each mold by using a spray gun or the like in this state, the coating agent is not applied to the parting surfaces and their vicinities.
