Abstract
An injection molding machine includes a stationary mold half and a movable mold half. The stationary and movable mold halves cooperatively define a mold cavity for injection molding an end closure article having a base and a recloseable tab molded in an open position relative to the base. A thermoplastic material is injected into the mold cavity to form the end closure article. The movable mold half is then separated from the stationary mold half to open the mold cavity, and the tab of the end closure article is closed prior to ejecting the end closure article from the open mold cavity.
