This process can be fully automated

Gives parts made a smoother surface

This process is able to produce a more accurate surface

This process uses permanent steel which is expensive

 This process allows metal to cool down and harden rapidly

This process uses high pressure by using a pump

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.

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.
