Has anyone experimented with using an inital dip in Investmnet prior to dipping in SS? I want to make little intricate things but the SS is nearly impossible to remove entirely. I was thinking that it would make clean up much easier. I cast 12-16 pieces in a single mold at a time. Investment casting that many pieces at a time is not efficient at all.
sounds like a good idea. Im having big problems getting shell out of deep detailing even with a sand blaster. Let us know how it works if you give it a go
Thought it might be a good idea, so I clicked his posts and got a surprise.. Check out the second one down. If it works, it would make clean up a lot easier.. Maybe dry wall mud would work as well as investment.
I tried it using RanCast investment. One cast was a 3" bust of Walt Disney out of PLA. tried one coat of Rancast and then 5 dips of SS. Burned out fine. Did not work. Pitted and just ugly. Just using SS they are beautiful. The other was a 6" US Parks plaque out of wax. I encased it in a 1" deep flat mold then dipped in SS when it was mostly dry. only did 3 dips. Burned out nicely. No cracking. Mold blew out and was a total loss. One using SS was perfect. So I will not be trying that method again again. Btw, all Brass castings
