Solus Wax Issues
Posted: Fri Jul 20, 2018 5:37 pm
My trials have been hit and miss so far. The white gold ring was my first attempt using this resin. It was cured for 30 min and burned out with a slow ramp. This casting was salvageable but it did have a section on the shank that did not come out. Not sure if this is investment breakdown (optima) or a resin related issue.
The next batch had different results. The two yellow gold rings came out good, although one better than the other. The one with the 3 dots had been cured for 20 min and had no surface defects. Ramped straight to 1450, held for 4 hrs then down to casting temp. The other one had not been cured and had a small section of pitting toward the base of the shank.
The gents ring is silver. This one did not cast well at all and will need to be redone. It was cured for 20 minutes and ran through the furnace with the yellow gold flasks. Straight to 1450 for 4 hrs then down to casting temp. 800F. I will try not curing and see what results that brings.
The rose gold came out good. Ran through with other flasks. No cure time. Other than the grow lines which is a separate issue. (Anyone have any ideas on this?)
It seems the heavier items are not casting for me for some reason. I'm not sure if it's a resin or investment/burnout issue. Mixing at 38 to 100. I've read some mix boric acid into their mix. Wondering what effects this might have with this particular resin. Any other suggestions?
