Comparison between Die Casting and Sand Casting

In diecast the mold or die is usually made of steel. So, materials and alloys with an equal or higher melting point than steel cannot be cast using the diecast process.

But in sand casting, the mold is made with special reusable sand. It can withstand very high temperatures and can be easily machined to the desired dimensions. For this reason, you can cast both ferrous and nonferrous metals using the sand casting process.
