Yifei Sand Casting can provide all types of valve body castings, which is a process where molten metal is injected at high pressure or poured into a mold containing a hollow cavity the shape of the part to form an object to a desired shape. The solidified part is known as a casting which is broken out or ejected from the mold to complete the process. Casting is most often used for making complex shapes that would otherwise be difficult or cost prohibitive to produce by other methods.
