ok, I gotcha Lake. more to do with the materials than the actual molding process then?
Usually sand casting is done for low volume production or R&D because the setup for die casting requires more $ to get started. There can be a problem with core shift not to mention the sand will work it's way out for a long time. In the case of China, I'm sure cost isn't much of an issue and probably the easiest for them. You can sand cast in your garage if you wanted. For producing alot of units and minimizing machining, die casting is the way to go.
