ABSTRACT:
A method and apparatus for resin molding upon an insert-member. The molding machine includes an upper die and a lower die, a cavity in at least one of the dies, a pot in which resin is introduced, and a resin path which allows the resin to flow from the pot into the cavity and onto the insert-member set in the dies. A film member is set between a parting face of the die and the insert-member. The film member covers a part of the insert-member corresponding to the resin path. An edge of the film member coincides with at least one of side edges of the cavity. The insert-member is clamped by the dies together with the film member when molding occurs.
