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.

Sep 6, 2023 · Lost-foam casting is a sophisticated technique for crafting intricate metal components by using expanded polystyrene (EPS) foam molds. Learn more about it here. How this metal casting process works and its best uses

Jun 17, 2024 · Lost foam casting is a type of evaporative-pattern casting process that utilizes foam patterns to create metal parts. The foam pattern, typically made from polystyrene, is coated with a refractory material and then buried in sand.

Lost foam casting is a type of evaporative pattern casting. This method is quite similar to investment casting which uses wax instead of foam in the pattern making process. The foam pattern was first used in metalworking in 1958.

Feb 2, 2025 · Lost foam casting involves creating a model cluster by bonding paraffin or foamed resin models similar in size and shape to the final casting. After applying refractory coating and drying, the model cluster is buried in dry quartz sand and vibrated to form a mold.

Production patterns are assembled using a precision, automated gluing machine. Glue is printed to one section of the foam and then pressed against the adjoining piece. Mold foam pattern sections. Age pattern to allow dimensional shrinkage. Assemble pattern if it is a multiple piece pattern. Build cluster (multiple patterns per cluster).

Apr 8, 2024 · Lost Foam Casting is an advanced casting process that offers several advantages over traditional casting methods, including greater design freedom, higher dimensional accuracy, and smoother surface finishes.

Lost-foam casting is a type of casting that leverages polystyrene pallets or molds to create high-detail metal pieces and parts. The process is ideal for casting complex small to medium metal products that maintain excellent surface finishes and high precision.

Feb 17, 2023 · What is lost foam casting? Lost foam casting is a casting method that uses expanded polystyrene (EPS) material, also known as styrofoam, as a patterned material and is planted in silica sand with the compaction of sand molds using a …

Jan 30, 2025 · The lost foam casting process is a method of metal casting where foam patterns are used instead of traditional metal molds. This process involves creating a foam model of the object you want to cast, coating it with a refractory material, and then using sand to create a mold around the foam.
