Lost-foam casting 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.

Lost Foam Casting
Lost foam casting is a type of evaporative-pattern casting process that is similar to investment casting but uses foam patterns instead of wax. Here is an explanation of this casting process:
Pattern Creation:
- In lost foam casting, a foam pattern is created by molding the pattern from polystyrene foam.
- The foam pattern is then coated with a refractory material to create a shell around the pattern.
Pattern Removal:
- The coated foam pattern is then placed in a flask filled with loose sand.
- Molten metal is poured into the flask, causing the foam pattern to vaporize and leave behind a cavity in the sand.
Casting:
- The molten metal fills the cavity left by the foam pattern, solidifying to form the desired metal part.
- Once the metal has cooled and solidified, the sand is removed to reveal the final casting.
Advantages of Lost Foam Casting:
- Complex shapes can be easily produced with intricate details.
- The process is cost-effective as it eliminates the need for expensive tooling.
- Minimal finishing is required due to the high surface finish of the castings.
In conclusion, lost foam casting is a versatile and efficient casting process that is commonly used in the manufacturing industry to produce complex metal parts with high precision.
