Investment Casting's advantages

There are a lot of advantages and disadvantages about the casting process on the Internet,but the details are not clear enough for the differences between the processes.
You can also find relevant casting process introductions and advantages and disadvantages on the wiki.

This article is used to compare the details between investment casting and other processes.


Die Casting vs. Investment Casting (precision casting)


Die casting is a metal casting process characterized by high pressure applied to molten metal by the mold cavity, similar to plastic injection molding.Die-casting is especially suitable for large and medium sized castings, so die-casting is one of the most widely used in various casting processes.Compared with other casting techniques, the die-casting surface is more flat and has higher dimensional consistency.

The biggest disadvantages is cost performance.

Using molten metal requires tooling that is made of hardened tool steel, which causes start-up costs to new programs to be extremely expensive.

Ferrous metals, like carbon steel and stainless steel, cannot be cast using this method, further limiting its usefulness.

Sand Casting vs. Investment Casting (precision casting)


Typical surface finish of sand castings are 250 Ra(which is 125Ra for investment casting) as cast, and need extensive work afterwards to create a surface finish. Sand castings can also not hold as tight of tolerances and will likely need more machining.
