Sand Mechanical Process Rectorite

The Nobake Process Nobake 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.

Shifting sand variables also may have a notable effect on the speed of a no-bake molding process. One of the most commonly overlooked and misunderstood sand-system variable is ADV (acid demand value). ADV is an indirect measure of the acidic or basic materials contained within the raw molding sand before the addition of chemicals.
