What Is Shell Mold Casting? It is also known as resin-coated sand casting process which is an expendable casting process that uses a resin covered sand to form the mold. In this casting process the mold is made like a shell, the thin or hollow mold is used so that weight of mold is less and handling of mold becomes easier. Shell-mold casting issuit for both ferrous and non-ferrous metals, most commonly used molten metals are cast iron, carbon steel, alloy steel, stainless steel, aluminum alloys and copper alloys.
Steps
Now, we've know What Is Shell Mold Casting, let's take a look at the steps of this casting process:
1. Pattern creation---A two-piece metal pattern is created according to the casting parts required.
2. Mold creation---Each pattern half is heated to 175-370掳C and coated with a lubricant. Next, the heated pattern is covered with the sand-resin mixture to form a mold shell
3. Mold assembly---The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold.
4. Pouring---The mold is securely clamped together. The molten metal is poured from into the gating system and fills the mold cavity.
5. Cooling---After the mold has been filled, the molten metal is cooled and solidified into the shape of the desired casting.
6. Casting cleaning---After the molten metal is cooled, the mold is broken and the casting is removed. Trimming and cleaning processes are performed to remove any excess metal from the feed system and to separate small sand particles from the mold.Wholesale Shell Mold Casting
