[QUOTE="lcmlabforum, post: 64123, member: 3238"] Now there is 2 Chris's - same person? Thanks Zubler Chris - good to have a well thought out explanation. Not that I don't trust you, but being a 'scientific' person, are there publications to support the hypothesis - ie. that a faster rate of heat and dropping it after reaching the temp, would bring temperature of all parts of the investment, ring and chamber to the same temperature? I supposed being used to old rings/ringless investments, we were trained to raise at 15 degrees/minute or something like that, to hold for some time to let all parts of pattern burn out and reach the right casting temperature, etc. This would seem counter intuitive that a faster rate of climb would create a more even temperature distribution pattern . . . but you guys probably have proprietary research data you cannot share? Would your technique work for conventional ring for casting alloys or only for a pressed method? LCM [/QUOTE]
