Adding to what Tim has said

There are a few cast items used in climbing equipment, but not many. Things like the tradition Jumar ascenders are cast, as are the spelean whaletales*

* this may have altered, since I bought mine, some time ago.

Castings are quite safe, when the casting process is done correctly, but mast casting aren't done through bottom casting at a low velocity. Poor casting techniques can lead to heaps of mechanical properties.

For prototype development, it might be cheaper just to get the equipment machined. There are a couple of manufacturing that might be simplier (although I don't know the costs) to do investment (lost wax casting) or to get the prototype HiPPed (metal powder heated and compressed)
