Originally, full mold process was referred to as Lost Foam Casting . But, later the two processes were clearly differentiated by the use unboned dry silica in LFC while bonded sand was used in full mold process. This process gained world famous, when General Motors first implemented it to manufacture 4.3L, V 6 diesel cylinder head, in 1981.
Vacuum molding (V process) is a variation of the sand casting process for most ferrous and non ferrous metals, in which unbonded sand is held in the flask with a vacuum. The pattern is specially vented so that a vacuum can be pulled through it.
Lost Foam Casting is a method that was developed in 1964 by M.C. Flemmings where he perfected an already existing foam casting process developed by H.F. Shroyer in 1958 known as quot;full mold processquot;. Both casting processes use foam patterns placed in compacted sand to form a mold.

The full mold process was originally known as the lost foam process. However, current patents have required that the generic term for the process be full mold. In 1964, M.C. Flemmings used unbounded sand with the process. This is known today as lost foam casting (LFC). With LFC, the foam pattern is molded from polystyrene beads.
Vacuum mold casting, also known in manufacturing industry as the V process, employs a sand mold that contains no moisture or binders. The internal cavity of the mold holds the shape of the casting due to forces exerted by the pressure of a vacuum.

THE LOST FOAM CASTING PROCESS Process Steps. 1. Mold foam pattern sections. 2. Age pattern to allow dimensional shrinkage. 3. Assemble pattern if it is a multiple piece pattern. 4. Build cluster (multiple patterns per cluster). 5. Coat cluster. 6. Dry coating. 7. Compact cluster in flask. 8. Pour metal. 9. Extract cluster from flask.
Lost Foam casting surface is usually better than all of the processes with the exception of die casting. In addition, the surface finish in the Lost Foam process should be consistent throughout the tool life cycle. Die cast and permanent mold surface finish will deteriorate as more cycles are run. ALUMINUM CASTING PROCESS COMPARISON

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.

DISAmatic casting The DISAmatic casting process is a container less sand casting process. The mold is divided upright. Front and rear mold half are formed by the shaped faces of every sand block. Stacked on a conveyor belt, the pouring cavity is between two blocks each.
The Lost Foam Casting Process This process eliminates the need for sand binders and cores. The sand is unbonded and a foam pattern is used to form the shape of the casting. The foam pattern is invested into the sand at the Fill amp; Compact process station allowing the sand into all voids and supporting the foam patterns external form.
