Lost foam casting(EPC)
Lost foam casting process can be used for iron casting and steel casting making. EPC (Expendable casting process) is to use metal patterns to create Foam patterns and assemble the foams into a foam pattern which is exactly like the parts to be made and later to use the coated foam pattern with loose sand to create the mould system by vacuum system for pouring. The foam will disappear during the pouring. Lost foam is one of the most eco-friendly casting processes. This process can also ensure very good dimensional precision.
