Shell Molding Process

Shell molding process offers better surface finish, better dimensional tolerances, and higher throughput due to reduced cycle times. 
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. 
A fairly high capital investment is required, but high production rates can be achieved. The process overall is quite cost effective due to reduced machining and cleanup costs.
The materials that can be used with this process are cast irons, and aluminum and copper alloys. Typical parts made with this process are connecting rods, gear housings, lever arms etc.
