INVESTMENT CASTING

Investment Casting, also known as Lost Wax Casting, is a precision casting process that provides design flexibility and significant cost advantages.

Investment casting is an industrial process based on lost-wax casting or precision casting.

Investment casting derives its name from the pattern being invested (surrounded) with a refractory material. Many materials are suitable for investment casting; examples are stainless steel alloys, brass, aluminium, carbon steel and glass. The material is poured into a cavity in a refractory material that is an exact duplicate of the desired part. Due to the hardness of refractory materials used, investment casting can produce products with exceptional surface qualities, which can reduce the need for secondary machine processes.

The process can be used for both small castings of a few ounces and large castings weighing several hundred pounds.

Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required.

Advantages

  • Excellent surface finish
  • High dimensional accuracy
  • Extremely intricate parts are castable
  • Almost any metal can be cast
  • No flash or parting lines

Applications

Investment casting is used in the aerospace and power generation industries to produce turbine blades with complex shapes or cooling systems.[13] Blades produced by investment casting can include single-crystal (SX), directionally solidified (DS), or conventional equiaxed blades.

Investment Casting Materials

  • Carbon Steel
  • Stainless Steel
  • Nickel
  • Ductile Iron
  • Grey Iron
  • There are several advantages of using investment casting to get the part you designed. One such advantage is the ability to make more intricate forms—even forms with undercuts. Also, the investment casting process leaves a very smooth surface, which is created without a parting line—something that would be unavoidable in other processes.

    The accuracy of investment casting is second to none. Even parts with the higher precision can be casted with little to no machining or detailing required. And since the finished piece will need no welding or assembling, you save on time and cost that would be required using other methods.

    With new alloys developed that allow for more complex parts to be cast, the process of combining several parts together to get the intricate shape can be eliminated. This not only saves time and money, but it also diminishes the chances that an error could occur while combining the parts.

    One of the biggest advantages of investment casting is that it is possible to produce a very wide variety of products across different industries. This versatility is a definite plus over other casting methods that either have difficulty producing some designs or cannot produce them at all. Also, many different metals and alloys can be used in investment casting, diminishing the need for designers to worry about the production of the casting they have visualized.
