Short explantion of Lost Wax Process:
The model of the part is made of wax from an aluminum die, then the wax patterns are connected onto the runner system which is also made of wax - it becomes a pattern tree or called pattern assembly. Then, the pattern tree will be dipped into ceramic slurry or stucco sand, with drying process between each coating until the shell is thick enough to hold the weight of molten metal which will be poured later.
Then the Pattern tree with wax in it is going to a high pressure autoclave which melt the wax out. It forms a hollow inside the shell. The shell is preheated before pouring, to help fluidity of the melton metal.
In the following process, the shell is broken and removed, so the castings can be seen now. The castings are then cut off from the metal tree and shot blast/polished/machined to get better tolerance and surface.
