Retouch / Filing gold castings

Hello all list members,

I am new to jewelry line and have recently set up a factory in
Thailand for manufacturing Gold & Silver Jewelry. After casting
the usual practice is to file and retouch each and every piece
and I observe this process is most expensive in terms of time
and metal loss. I am looking for some solution which could avoid
this step; I mean is there any way that the casted metal is
received in such fine condition that it would not require any
filing / retouching. I appreciate advise from experienced
members. Regards
