This process can be fully automated

Gives parts made a smoother surface

This process is able to produce a more accurate surface

That the pattern can be easily taken out of the sand without damaging the cavity in the sand.

The cope and drag are clamped together securely during the pouring of the molten metal.

The desired cavity in the final castings are formed

There is adequate material to fill the cavity during the cooling and solidification of the molten metal.

The desired cavity in the final castings are formed.

That the pattern can be easily taken out of the sand without damaging the cavity in the sand.

The cavity in the sand in the cope and drag matches up to form the intended geometry.

The cope and drag are clamped together during the pouring of the molten metal.

There is adequate material to fill the cavity during the cooling and solidification of the molten metal.

Machining is needed to ensure a smooth surface and precision in location.

Machining should be kept to a minimal to save cost.

Cores can be used to reduce the amount of material removed during machining, saving on machining cost and material usage.

Casting usually leaves a slightly rough surface. For regions that do not interact with other parts, machining is not required.

Molten steel is highly reactive with the gasses in the environment.

Cast steel products are unsuitable for machining and hot forming.

Steel has a high melting point.

Molten steel does not flow easily.

Casting does not bring out the good mechanical properties compared to other means such as hot forming processes such as forging and hot rolling.

The part need to be lightweight.

The part needs to be made out of metal.
