In investment casting,wax is used for the casting,generally
it is made for the small pieces and is made 100s of pieces
per casting while in other casting process,we cant make this
amount of casting at a time.
In this,initially the wax is injected in the die,then it is
allowed to cool down,then the wax object is removed from the
dies and the trees is made from this wax object. Then
plaster of paris is into the cylinder and the tree will be
already there in the cylinder.Then after this cylinder is
allowed to solidify and then after it is heated.
due to this heating process,the wax will evaporate and will
stick with wall and thus cavity will be created.
So then after the molten metal will be poured in the cavity.

When in other casting,simply molten metal is poured in moulding.
