No-bake is a casting process that involves the use of chemical binders to bond the molding sand. Sand is conveyed to the mold fill station in preparation for filling of the mold. A mixer is used to blend the sand with the chemical binder and catalyst. As the sand exits the mixer, the binder begins the chemical process of hardening.

molding sand and core sands, controls both the surface area and the packing density or porosity of the mold. The porosity of the mold controls its permeability, which is the ability of the mold to allow gases generated during pouring to escape through the mold. The highest porosity will result from grains that are all approximately the same size.

To produce a typical mold using no-bake binders, the pattern is covered to a depth of four to five inches with no-bake sand mixture. The sand is then allowed to set for a period of time at room temperature before the pattern is removed from the mold. The depth of the no-bake binders will vary depending on the size and weight of the casting.
