Comparison of casting processes

Here are the Comparison of casting processes in a table. Thanks. Feel free to comment. 
Castings process name
advantages
Disadvantages
Sand castings
Ä      Any metal can be cast
Ä      No limit size and shape
Ä      Less equipment cost
Ä      Economic for low volume production
Ä      Coarse final
Ä      Dimensional accuracy is not good
Ä      Finishing required
Ä      Less production rate
Individual casting
Ä      Any metal can be cast
Ä      Good surface finish and dimensional accuracy
Ä      Fairly high production rate
Ä      Less finishing cost
Ä      Interlaced shape can be cast
Ä      High labor cost
Ä      Expensive patterns and mold
Ä      Limitation on part size
Die castings
Ä      Excellent surface finish
Ä      Excellent dimensional accuracy
Ä      High production rate
Ä      Complex shape can be cast
Ä      Little or no finish cost
Ä      Limitation on part size
Ä      High cost of die
Ä      Generally limited to casting of non ferrous metal
Lost-wax casting
Ä      High production rate
Ä      Good dimensional accuracy
Ä      Good surface finishing
Ä      Expensive setup
Ä      Good for production of cylindrical parts only
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
