Unscrewing / Rotating-Core Molds

Unscrewing / rotating-core plastic injection molds

When internal or external threads are required on a plastic part, unscrewing or rotating core molds are utilized. In order to actuate the rotating cores, different drive systems can be incorporated and the action is coordinated with the press cycle so that extraction occurs when the mold is opened. As one of the pioneers with unscrewing molds, Janler brought the first unscrewing stack mold to market.
