When manufacturing metal models with complex shape and irregular curved surface, if there are a large number and they are required to be accurately interchangeable, they can be manufactured by gypsum model. The metal model made of gypsum model is different from that made of wood. It can only be made of "complex model", that is, the gypsum slurry is poured on a solid model to obtain a discordant mold completely consistent with the practical model, and then the metal mold is cast in the gypsum model. The following is an example of an iron mold for a plowshare to illustrate the engineering procedure for manufacturing a gypsum mold.
