Abstract: An improved a sand casting line where in sand molds are carried on cars along at least a first and second linear parallel yet opposing paths, including an endless loop conveyor positioned proximal a discharge end of one of the linear paths and a loading end of the other of the linear paths, with a plurality of car supporting elements carried thereon, such that a car can be discharged from the discharge end on to a supporting element simultaneously with a second car being loaded from a supporting element onto the loading end.

Abstract: An arrangement for forcing rapid localized directional solidification, or global homogenous accelerated solidification of a liquid or semi-solid parent material, which is contained by a media mold that possesses porous properties. The process produces solidified matrix structures and cast properties in the parent material otherwise not possible through conventional solidification methods under ambient conditions. The process is capable of enhancing ordinary production cycles by reducing the overall cycle time required to produce a normally solidified material in a porous media mold.

Abstract: A conveyor system for use in a lost foam casting system connects a plurality of stations where operations necessary to the process are carried out. The system utilizes an interconnected train of open frame gondolas supported on a set of elevated parallel horizontal rails forming a closed loop. The gondolas each support a flask wherein molds are placed and sand molds are compacted, with the flasks being removable from the gondolas as necessary for the particular operation. A programmable controller senses the status of the system and provides signals to operate the conveyor and associated components.
