Undermold Lid System

The Martin Automated undermold lid system is designed to orient lids molded with a four-cavity stack mold. The system starts with a lid catcher. And the lids are conveyed out from under the molding machine in single file with the lid’s bottom side up. The ultimate purpose is to convey the lids to a gasket and spout installing machine. The lid stacker provides a buffer if the automated lid system is halted. To watch the function of the machine, please see the video.
