The investment casting process is generally used for small castings. It is generally more expensive per unit than die casting or sand casting, but has lower equipment costs. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
    Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems.Blades produced by investment casting can include single-crystal (SX), directionally solidified (DS), or conventional equiaxed blades.
    Investment casting is also widely used by firearms manufacturers to fabricate firearm receivers, triggers, hammers, and other precision parts at low cost. Other industries that use standard investment-cast parts include military, medical, commercial and automotive.

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.

Casting tolerance can be controled within +-0.15mm.

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.
