Investment Casting


INVESTMENT CASTINGĀ I023

Also called the “lost wax” process.

The piece is shaped from wax, coated with ceramic and then the wax is melted out to leave a hollow vessel for the metal to be poured in.

Investment cast impellers are preferred because you can cast in a compound curve that allows the impeller to pump abrasives with less energy and wear.

The compound curve in the impeller acts in the same manner as the angle on a snowplow. Without the angle directing the snow to the curb, it would require a lot of energy to push the plow.
