Investment Casting Part

We have two types of investment cast processes. They are the shell process (Colloidal Silica process) and the water glass process. A wide range of alloys is available for both processes. They include carbon steels, low alloy steels, stainless steels, tool steels and copper based alloys. Please check the technical specification sheet for materials available. Shell investment cast parts can range from a weight of just a few ounces to approximately 100 pounds-45Kg. Water glass castings may range in weight from several ounces to approximately 200 pounds-90Kg. 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.
