Advantages of investment casting:

Investment casting surface finish is generally 3.2 to 6.3 Ra that is much smoother than sand casting or shell molding this means you have a finer detailed parts.
Tight tolerances CT3-CT6 and great repeatability are possible so you get more accurate and consistent parts.
Aluminum molds can be used for low qty production runs which will save you money.
The range of alloys that can be investment cast is very large so you can optimize your parts to take advantage of economical or performance alloys.
The parts have superior structure and metallurgical properties.
Cost savings are possible because of the complex design that are possible to cast using this process. Also the elimination of many secondary machining operation also reduce costs.
Fine details like lettering, logo, slot and holes are easily done with lost wax casting
