I work for a jewelry design studio and we’ve been experiencing problems with casting and I wanted to know what everyone else does. So when we send our projects to casting, they said that they “scale down” ring sizes 1/8-1/4 of a size and then there’s additional shrinkage that takes place during the process. Rings have been coming in 1/2 size too small which makes detailed rings in particular problematic.
I’ve had CAD designers say that they’ll bump up the size to account for additional shrinkage but then this messes with what size the casting partner thinks it is so they’ll try to keep the ring that size as much as possible. One way doesn’t always work. What does everyone else do, we want our rings to be 1/8-14 size smaller for obvious polishing/finishing reasons. Let me know any advice thanks!
