ABSTRACT:
A molding system comprising molding units mounted on a truck on rails laid at right angles to a plurality of equi-spaced, parallel pouring lines. Each molding unit consists of a flaskless molding machine and a pusher for the product molds. The molding machines are operated with different but coordinated fluid pressure settings for the drag, cope, and match plate in such a manner that those components do not put any restraint upon the movement of a squeeze table.
