Investment Casting can yield any required shape using almost any metal alloy; design functionality can be maximized due to the amount of materials to choose from. Various features can also be incorporated with the right mold. The most popular materials that are suitable for Investment Casting are stainless steel, carbon steel, copper, aluminum, and superalloys.
Investment Casting is the preferred process for creating complex castings as it allows for complex parts and components to be cast. Sections with thin walls and features, such as undercuts, can be cast with ease. Investment Casting can also produce a superior surface finish up to Ra 3.2 and achieve dimensional and geometrical accuracy to meet special requirements such as weight.
With Investment Casting, designs do not have to be altered to add different angles or taper. In addition to providing design flexibility for manufacturing complex, one-piece structures, this is an added advantage as it reduces secondary machining time and also drastically reduces material and processing cost.
