Stainless steel investment casting with CNC machining and polishing surface
We have two types of investment cast processes: Silica Sol process and the water glass process.
The Silica Sol 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 is capable of much larger castings than the
Silica Sol process, but does not have as good of surface finish or
tolerances. The water glass process provides parts that have better
surface finish and dimensional tolerances than sand castings.
Silica Sol investment cast parts can range from a weight of just a
few ounces to approximately 80 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
200 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 include heat treatment, machining,
plating, painting, polishing and buffing, assembly services and
even custom packaging.
