Investment casting process describing:
We offer customers two types of investment cast processes
They are the shell(Silicasol) process and the water glass process
The shell process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances
The water glass process is typical of the process in the early stages of investment castings
It generally capable of much larger castings than the shell process, but does not have as good of surface finish or tolerances
Water glass process provides parts that have better surface finish and dimensional tolerances than sand castings
A wide range of alloys is available for both processes
They includes carbon steels, low alloy steels, stainless steels, tool steels and copper based alloys
Other material may be available upon request
Shell investment cast parts can range from a weight of just a few ounces to approximately 50 pounds
If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations
Water glass castings may range in weight from several ounces to approximately 175 pounds
First article layouts and spectrometer material certifications are provided with all first article samples
A variety of secondary operations can be performed on both types of investment castings
They includes heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging
