Abstract:
Recycling of exhausted wax in a process of lost wax micro casting.

Claim (Index 1):
Process of lost wax micro casting with recycling of exhausted wax, comprising the steps of:\n molding of one or more wax models, identical to the end pieces to produce, using a first formulation of wax; molding of one or more molds of sprues (connecting passages), using a second formulation of wax; assembling of said one or more models and said one or more molds of sprues, to form a cluster; coating of said cluster with a ceramic shell; removing of wax from said shell; treating of said shell in an oven; casting of molten metal alloy within said shell and subsequent cooling to obtain a solidified casting; cracking of the shell to release the solidified casting; removing of the sprues and finishing of the pieces; and characterised in that it additionally comprises the following steps: melting of the exhausted wax coming from said step of removing wax from said shell, to obtain a molten exhausted wax; removing of water from said molten exhausted wax, to obtain de-hydrated molten exhausted wax; removing of ceramic residues, ashes or other impurity by filtration of said de-hydrated molten exhausted wax, to obtain recycled wax; adding virgin wax (grade 50-60\u00b0 C.) in a quantity equal to at least 30% by weight of the total of the recycled wax, and at least equal to the amount of recycled wax in the case in which the same has been already obtained following a process of lost wax micro casting in which a wax formulation that contain recycled wax was used, to obtain said second formulation of wax; delivering of said second formulation of wax to said molding of one or more molds of sprues; wherein said second formulation of wax has the following properties: freezing point: 58-64\u00b0 C. metting point (drop melt point): 65-71\u00b0 C. ash content: \u22640.05% by weight penetration: 8-14 dmm viscosity at 70\u00b0 C.: 0.6-1.3 Pa\u00b7s where the penetration is measured accordin to ASTM D1321 needle enetration of petroleum waxes), using a weight equal to 250 g and the viscosity is measured using a Haake RV1 absolute viscometer with a ISO 3219 Z34 DIN cylindrical rotor with, a diameter of 34 mm, using a cutting speed of 54.5 s-1 and a cooling rate of 1 degree per minute in a temperature range that starts from 85\u00b0 C. to 60\u00b0 C.
