The difference Between Investment Casting and Precision Casting
Investment casting is a casting technique for making accurate castings in steel and iron materials by using a mold formed around a pattern of wax, then melted the wax and pouring the steel or iron water into the sand shell.
Precision casting is another name of investment casting. It’s called by different people from different countries. By using precision, people can know that the dimension accuracy for castings made in investment casting or precision casting is much better than sand casting.
Materials used for investment casting and precision castings are almost the same. The mainly used are carbon steel, alloy steel, stainless steel, grey iron, gray iron, and ductile irons. Some white irons, such as Ni-hard 4, Hi chrome, or high nickel, can also be used for precision casting or investment casting processes. The specific casting process is lost foam casting.
