What casting method should I use- production work

[mattsam]

I have a few production parts I will need casted. I'm thinking sand, but let me know if I'm wrong.

Material 316SS
Qty 100 pcs for now up to 5000 per year, BUT only 100 now
4" OD of part, nothing bigger than 4.5" x 4.5"
Critical features need to be machined


Thank you
Matt

Investment casting.

I agree, ceramic shell or investment casting depending on the size of the parts.
