Lost Foam

You are here

In lost-foam casting process a pattern of the desired cast-part is made from expanded materials (foam) , then the pattern is dipped into a ceamic coating and after drying, it is put in molding sand. After pouring the melt, the foam is lost and vaporized and the cast-part is formed . Lost foam process has several advantages over other casting methods :

1- Environmentally friendly, pollution reducing process.

2- Better quality in acquiring necessary smoother surface quality.

3- Cost reduction in cast-part machining.

4- Flexibility in designing complex components.

5- Omission of sand cores in molds.

6- Additional possibility for weight reduction.
