Abstract
A manufacturing method forms flanges for use in a film cartridge which are made of resin. Each flange is made of the resin by an injection molding process. Gates to cavities provided in a mold are located such that residual portions of solidified resin at the gates, remaining after the injection molding process has been completed, do not come into contact with a film in the cartridge as the film is moved into and out of the cartridge.
