Die Casting has less size limitation than investment casting and can creat larger components, but it will cost more in both tooling cost and unit cost for larger products.
So it seems like a high cost casting method. Investment casting is also the most possible technique to reduce or aviod seconary machining, which reduce both time and money.
Die casting cost more due to its high tooling cost and sometimes post machining operations for finished components. So die casting is more cost effective for large order quantity. While die casting produces good surface finish, more machining is usually needed to get the product to its final state.
But we can both improve the surface finish of investment casting and die casting by secondary machining and other surface treatment ways. No matter which process is choosed for your project, it all depends on your specific needs of products, as each process has its own benefits. Investment casting is considered when you have a small product with complex shape.
And the material is steel or iron. If you are looking for a casting method with high volume, and the material is alunumin or zinc, then die casting is your right option.

Investment casting may also be called precision casting, or in some cases, lost wax casting. It starts by the caster creating a wax pattern in the shape of the desired part.
The wax shape is attached to a tool called a sprue and then repeatedly dipped into liquid ceramic until the ceramic hardens around the wax shape, taking the shape of the casting.
The caster then heats the mold so the wax melts away, leaving a cavity within the ceramic, which the caster can then fill with molted metal. Once the metal cools and hardens within the ceramic mold, the mold is shattered, leaving the cast metal part complete. Investment casting is used if you need zero draft angles on the part, something die casting cannot offer.
Investment is more suited to lower volume quantities since the tooling is less but the part prices is higher than die casting. Die casting works by forcing molten metal into a die cavity with high pressure. The caster machines a die cavity tree with hardened tool steel in the shape of the desired parts. Investment casting is capable of casting cast those metals along with ferrous metals, including stainless steel.
If you are looking to use a non-ferrous material, both processes offer comparable features. However, if you are looking to use stainless steels or copper alloys, investment casting is the better option. When deciding which casting process to use, decide what your desired payback period is for the tool cost. With any casting process, tolerance capabilities are largely influenced by the shape of the part and the type of material used.
The table below compares general linear tolerances for conventional die casting and investment casting. The multi-slide die casting process is capable of holding even tighter tolerances. While investment casting and die casting both produce complex parts, the cycle times differ greatly. Traditional investment casting is a timely process that requires quite a bit of labor and hours of work, while die casting can produce shots per minute for conventional die casting and upwards of 45 shots per minute with multi-slide die casting.
A die cast part can often times be created without the touch of a human hand—complete automation!
