contents, especially high Al + Ti, which renders the superalloys virtually impossible to hot working (e.g. Alloy 939) must be cast into rather small diameter ingot sticks typically 5 inch diameter as stock for small castings – and directly suitable for the re-melting in an investment casting furnace.
Our inventory of superalloys includes duplex alloys, hastelloys, nickel based, nickel-chromium, cobalt based, and proprietary combination alloys. We specialize in highly repeatable short production runs of superalloy investment castings in the 0 to 20 lbs range, and can produce 100+ lbs castings when required, as well as:

Investment casting of nozzle guide vanes - SpringerLink
Nov 20, 2014 · Nozzle guide vanes (NGVs) are important structural parts of gas turbines .NGVs are typically made from Ni-based superalloys because they have to withstand very high temperatures and aggressive environments .Investment casting in vacuum, also often referred to as lost-wax process, is the only commercially used manufacturing route of these parts that have very complex shapes .
Tech Castings produces both vacuum and air melt lost wax investment castings. We have a pouring capacity of 50 pounds and part dimension capabilities up to 20" x 20". This allows us to handle larger castings with ease.

Investment Casting Foundry Investment Casting Company
American Casting Company is an ISO 9001 and AS9100 certified investment casting foundry and investment casting manufacturing company that delivers premier quality investment castings with the industry’s shortest lead times.
Investment casting is a precision casting method which is growing steadily in international significance for reason of economy. The method is being used to produce larger and larger castings. Investment castings is also employed on an increasing scale for so-called super alloys which require ever more complex smelting processes.

Materials that are suitable for investment casting include stainless steel, aluminum, superalloys, low alloy steel, and titanium. The process can be used for castings of various sizes, from a few ounces to several hundred pounds. Investment casting first involves a wax pattern being enclosed in a ceramic shell to create a ceramic mold.
Process Description. Waukesha’s Investment Castings are produced using the Full Mold process. Full Mold Investment Casting (FMIC) is a type of evaporative-pattern casting process where special foam is used for the pattern material instead of wax as in the traditional investment cast process.
