Abstract
A method and system is provided for operating a molding machine to prevent damage when replacing a mold. The molding machine includes movable and fixed magnetic platens to open and close a mold. The system includes a flux sensor. When a set-up mode is selected, an electronic processor is configured to: enable movement of the movable magnetic platen when the crane is above the molding machine; the molding machine receives a crane load signal that is less than a marginal load value; and the flux sensor senses that the magnetic platens are magnetized and the magnetic circuit is completed; and enable movement of the movable platen to remove/insert the mold when the crane is above the molding machine; the molding machine receives a crane load signal wherein a load is greater than the marginal load value; and the flux sensor senses that the magnetic circuit is not completed.
