Custom Component Manufacturing www.pacriment.com Phone: (800) 928-9108 Fax: (516) 797-1819 Email: info@pacriment.com lost foam aluminum 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 foam to simplify the investment casting process by removing the need to melt the wax out of the mold.
