Investment castings are typically selected because they can be produced with fine detail, excellent "as-cast" surface finish, shape into internal or external features, thin walls, and internal passageways to get to a near-net shape. This often leads to significant customer cost savings in material, labor and machining.

In lost wax investment casting, a sacrificial detailed wax pattern of the desired finished part is created and mounted onto a wax "tree", which includes the metal delivery system (gates and risers). The tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and is allowed to dry. This process is repeated until a thick shell is created over the wax pattern. The wax pattern is melted out leaving a cavity in the shape of the pattern. The cavity is filled with molten metal. After solidification, the shell is broken away, the gating material removed, and the finished part remains. Check out the below video to learn more.
