LOST WAX CASTING | PROCESS

1 Creating an object 3 Fireproof clay is put into the impression, making a sharply defined duplicate of the original model.

5 Hot wax is poured into the gap which produces a clay model covered in wax

7 A finely granulated flour is applied to the surface of the model for making an “investment mold"

8 Pouring in the liquid bronze at the top

2 The model is put into a bed of elastic and shapable material held in place by a rigid outer mold. When the model is removed, its impression remains.

4 When this second model is returned to the mold, there is a gap between the model and the mold for pouring wax.

6 Wax pipes are attached to the wax-covered model for flowing molten wax, molten metal and air when pouring metal in.

9 Breaking the cladding and investment mold for getting the bronze model
