Shell
Molding
Casting
This
process can produce complex parts with good
surface finish 1.25 µm to 3.75 µm
(50 µin to 150 µin) rms, and dimensional
tolerance of 0.5 %. Size limits of 30 g to
12 kg (1 oz to 25 lb). Minimum thicknesses
can be as low as 1.5 mm (0.062 in) to 6.25
mm (0.25 in), depending on the material. A
good surface finish and good size tolerance
reduce the need for machining.
The
materials that can be used with this process
are cast irons, and aluminum and copper alloys.
