Casting modeling method and production system

The invention discloses a casting modeling method and production system. The casting modeling production system comprises a conveying rail and a plurality of treating devices arranged along the conveying rail, at least one of the treating devices is a linkage treating device which comprises at least two treating mechanisms, and all treating mechanisms in the same linkage treating device act at the same time to simultaneously treat at least two objects to be treated, which are conveyed along the conveying rail. Since at least one of the treating devices in the casting modeling production system is a linkage treating device used for simultaneously treating multiple objects to be treated on the casting modeling production system, so the working efficiency of the casting modeling is improved.
