Investment Casting for Aerospace

Many aerospace components are produced through investment casting. Aerospace components must withstand extreme weather conditions, pressure, and other factors that cause operational wear—thus, these components require superior inherent durability. The consistency and precision of parts provided by investment casting can significantly improve tensile strength. Manufacturing aerospace parts through investment casting also ensures that interlocking parts can mate quickly and easily, preventing assembly errors that can cause excessive wear or failure.

Key Benefits of Investment Casting for Aerospace Components

Investment casting is ideal for producing aerospace components for the following reasons:
Investment casting produces parts with the delicate designs, thin walls, undercut holes, and slots that are often required for aerospace components.
Parts made with investment casting will have an excellent surface finish, reducing or eliminating the need for secondary operations.
Investment casting produces parts in a variety of sizes and weights.

If you are evaluating investment casting for your aerospace component needs, consider the following:

Variety of Alloys and Materials

Investment castings can be made from a variety of alloys, and the final product can gain the benefits of multiple metal qualities at the same time. Alloys frequently used in the aerospace industry include:

Aluminum
Stainless steel
Titanium
Superalloys

Material selection is critical because it affects the unique physical properties that the final part possesses. These properties include enhanced chemical and corrosion resistance, durability in extreme temperatures or other hazardous operating conditions.

Tight tolerance ranges

Every measurement is allowed to have a certain degree of deviation from the set specification, including thickness, diameter, and other related measurements. The closer the final part can adhere to the measurement requirements of the application, the better its performance. Investment casting can adhere to very tight tolerance ranges, thereby improving the functionality of complex single parts and complex systems containing multiple parts.

Comprehensive design process

Designers rely on a variety of software (such as CAD and CAM) and technologies when they begin to create investment casting parts and prototypes. Successfully completing the steps in the initial design phase is critical to the long-term performance of the component. For example, prototyping allows designers to stress test the part and determine its operability in the actual environment.

Thin and streamlined parts

Investment casting designs can be created with thin walls without the risk of losing structural integrity. These examples include undercuts, grooves, threads, etc. Integrating critical assembly requirements into components is not a problem for the investment casting process.
