Investment casting is metalworking process which molten metal is poured into a mold. This mold is covered by several ceramic shells. Afterward the mold is left to be cold and the molten liquid metal takes the exact shape and size of the mold.

Investment casting is one of the casting process that is different from sand casting and die casting which traces back to centuries ago.

This method is considered to be the best method of casting. Because of remarkable surface finish and delicacy it’s known as precision casting too.

Most of parts with complex geometry and internal shapes can be created by investment casting and as a single part with zero draft angle.

Reducing secondary operation: With the great surface finish of investment casting there is less needing for secondary operation and welding so it saved a lot of labor cost and materials.

Complexity: If you have complex part with cavity and thin walled thickness investment casting is the right choice for you due to less machining.
