Investment Casting Lot Traceability
Investment Casting Lot Traceability
(OP)
I work in an industry where lot traceability of each individual component is of the utmost importance. To control lot ID during the casting process, the lot ID is hand etched into the wax and thus transferred to the part. The part once casted is then laser etched and the original lot ID is belted off. This process really bugs me. Im thinking of switching to a cast-in lot code where a ID tab is placed in the wax prior to casting. This process does not eliminate the human element though, and still provides an opportunity for lot tracebility problems. The idea of laser etching the wax prior to casting is also being investigated.
Those that utilize investment casting or similar process, how do you provide lot traceibility per component?

That is what I referred to as a cast-in lot code. Essentially a tab is placed in the wax with the lot ID on it and thus be transferred to the casting.
Again, ideally I would like to minimize the human element as much as possible. Placing each individual lot code tab in the wax as well as the cost of each tab almost off-sets quality/cost savings.
Thanks
