Metal Casting Processes user's Blog!. NO BAKE As well known, there are several modalities to obtain excellent castings, no matter whether made of cast iron, steel, or aluminium. Among the most diffused methods, it is possible to list processes of sand/resin, green, die-and lost-wax casting, as well as fully different processes like pressure die-casting. Each of them features, For example, a cold-box sand casting core binder is sodium silicate which hardens on exposure to carbon dioxide. Special binders are used in air-set sands to produce core at room temperature. These sands do not require a gas catalyst because organic binders and a curing catalyst are mixed together in the sand which initiates the curing process.

Our No-Bake Casting Foundry consists of two production molding areas producing castings up to 36,000 pounds. The lines are equipped to support flask sizes up to 144"Г—144". In addition to standard flask molds, Willman is capable of producing no-bake molds in mold boxes or with loose patterns. 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.
