Are you trimming the metal too thin? That's the only thing I can think of that might be causing you problems.
hi aidhira, you are right. That was happened to me before when I trimmed NP too thin. Dr. send the case back after he took a new impression, but the redo failed again. Margin shorted after de-oxidized (1000 F),three bakes and finished. It drives me crazy.
I wanted to share one more experience with our forum is when I use NP contained Be, and high casting temp (1550 F),creeping does not appear, and I am sure that I trimmed metal the same way I did before. Short margin on metal happens only with the metal contained no Be, and casting temp is lower at 1450 F.
Any body have an answer?
However like AL, Sixonice, John Wilson suggested, I changed my metal and kept the margin thicker.
Next question is for BMS. How much Talladium charged you per Tillite ounce? I have a quote from Talladium six months ago and they charge about $40.00/ounce?!
Thanks every one
