Evaporative-pattern casting is a type of casting process that uses a pattern made from a material that will evaporate when the molten metal is poured into the molding cavity. The most common evaporative-pattern material used is polystyrene foam. [1] The two major evaporative-pattern casting processes are: [1] Lost-foam casting; Full-mold casting
Full-mold casting is an evaporative-pattern casting process which is a combination of sand casting and lost-foam casting. It uses an expanded polystyrene foam pattern which is then surrounded by sand, much like sand casting. The metal is then poured directly into the mold, which vaporizes the foam upon contact. Full-mold casting
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
Foam glass or expanded glass is a porous glass foam material. It is used as a light weight, moisture- and fireproof building material with thermal and acoustic insulating properties. It is made by heating a mixture of crushed or granulated glass and a blowing agent (chemical foaming agent ), often carbon or carbonates such as limestone .
OpenFOAM (Open Field Operation And Manipulation) [8] is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the solution of continuum mechanics problems, most prominently including computational fluid dynamics (CFD).
In cuisine, foam is a gelled or stabilized liquid in which air is suspended. Foams have been present in many forms over the history of cooking, such as whipped cream , meringue and mousse . In these cases, the incorporation of air, or another gas, creates a lighter texture and a different mouthfeel .
