Ä
Limitation on part size
Ä
High cost of die
Ä
Generally limited to casting of non ferrous metal
|
Lost-wax
casting

|
Centrifugal
casting
|
Ä
No limit size and shape but mainly spherical
Ä
Surface finishing smooth
|
Ä
Not all alloys can be cast in this way
Ä
An inaccurate diameter of the inner surface of the casting
