The Silica Sol process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances.
This process can range from a weight of just a few grams to approximately 50 kilograms. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations.
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.
This process may range in weight from several grams to approximately 120 kilograms.
First article layouts and spectrometer material certifications are provided with all first article samples.
Custom service: 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.
