Precision Investment Castings
Investment Casting, also known as Lost Wax Casting, is a precision casting process that provides design flexibility and significant cost advantages.
Investment Molding Process
The Investment Casting process involves pouring molten metal into a mold that has been created using a wax model. Once the mold is made, the wax model is melted and drained away. Hollow cores can be affected by using a heat-proof core that prevents the molten metal from totally filling the mold.
Investment Casting is generally used for small castings, though it can be used to produce much larger components.
Dimensional tolerances of ± 0.003 in./in. are readily achieved with the investment casting method.
Delicate parts with walls as thin as 0.025 in. can be created by utilizing investment casting.
