▶ Capabilities of Lost Foam Casting

▶ Inspecting Lost Foam Castings

▶ The general lost foam casting process are as in the following:

Use foam molds to produce foam patterns and casting gating systems
Bond the patterns and runners to form a mold bundle module
Dip paint on the module with refractory materials
Dry the paint
Put the module into the sand box and fill it with dry sand
Vibrate molding in order to fill the cavity with dry sand and then compact the molding sand
Pouring molten metal to vaporize the foam and then forming the desired castings
After the castings have cooled, clean the castings. The dry sand can be recycled

▶ Post-Casting Process
