Lost foam casting, also known as solid mold casting, is a new casting method that involves bonding and assembling foam models similar in size and shape to the casting into a cluster. After applying refractory coatings and drying them, the models are buried in dry sand, vibrated to form the mold, and then cast under vacuum to vaporize the models. The molten metal takes the place of the models, solidifies, cools, and ultimately forms the casting.

The lost foam casting has the following characteristics:

Castings of high quality with low cost. Suitable for various materials and sizes; high dimensional accuracy, smooth surface finish, reduces cleaning, saves machining time; significantly reduced internal defects, dense structure.

Achieves large-scale and bulk production. Automated assembly lines promote environmental protection. Can significantly improve working conditions, reduce labor intensity, and minimize energy consumption.
