Solid Mould
The mould block : Around the assembly of wax models, we place a metallic chassis.
A ceramic refractory is poured in vacuum, thus forming a mould that will be heated in an autoclave to eliminate the wax, and then fired in order to carry out a preheating of the ceramic. The temperature homogeneity in the mould, confers an advantage to the casting of light alloys.

Shell
The assembly is emerged into a slurry and is then covered in zirconium sand until a crust is obtained with a thickness of 8 mm (5/16 inch) around the model which is then called a shell.

N.B. : Parts made by both of these techniques have dimensional capacities of over 1m long (40 inches) in each direction.

Ceramic Cores
One facility has elaborated a composition of special ceramic to produce ceramic cores compatible with the casting of the aluminium, easily removable.
This technology allows us to obtain a good price/performance ratio and to assure a perfect mastery of the surface finishing of the more complex parts.
