Casting temperature:

100° C over its melting temperature to cast with centrifugal machines.

140° C over its melting temperature to cast in outdoor cylinders with vacuum.

120° C over its melting temperature to cast in vacuum machines with controlled atmosphere.

Cylinders temperature: from 550° C to 650° C depending on the machine and

objects dimensions.

Cooling casted objects: in water after 10 minutes.

Cooling casted objects (with stones): in water after 30/40 minutes.

Annealing: 620° C for 20 minutes followed by a quick cooling in hot

water (40° C min.)
