An Example in Steel  Casting  --  Lever Arm in the BMW Engine Valve Train

Conventional Gravity Casting 

Gravity Casting

In gravity casting  the melting and pouring process consists of two steps in an open atmosphere.

1. Heat the metal in the crucible to the casting temperature.   

2. Tilt the crucible and pour the liquid metal into the mold.

Allow the mold and casting to cool. Remove the ceramic mold, leaving individual castings connected to the central sprue and gate system.

Which casting process (Conventional Gravity or Countergravity Low Pressure Air - CLA ) is best suited for producing the lever arms?
