The investment casting shell is a repetition of the process of "coating-sand-drying. However, for castings with long holes and narrow grooves, it is difficult to cast them when the ratio of hole depth to hole diameter H/d>5, and the ratio of groove depth or length to width of narrow grooves is greater than a certain proportion, which is often realized by mechanical processing. For long holes with slightly larger diameter, although the shell can be made, it has been filled with slurry and sand, increasing the probability of shrinkage and porosity defects. Today, Yufeng metal, a precision casting manufacturer, discusses several methods of investment casting for this kind of castings.
