1. Low initial tooling costs : Initial tooling costs averaged over the parts produced are often less than other manufacturing tooling costs.

2. Elimination of material waste : Investment castings are essentially cast to size, thus decreasing the amount of machining required.

3. Design flexibility and capability: Infinite choice of alloys and design flexibility for internal and external configurations is seen as a plus.

4. Design enhancements: There is no draft requirements in the investment casting process.

5. Consistency: The process gives a reliable and consistent product order to order.

6. Close Tolerances: Consistently produced close tolerances over other processes is seen as an advantage.

7. Surface Finish Improvement: A surface finish of about 125 RMS is common for an investment casting.
