Thanks for your replies, I've also obtained some more information on the oven and read up on radiative heat transfer (Thorne - Technology of Thermoforming). Hopefully I am now sufficiently armed to solve the problem.
Only one side of the sheet can be measured, however the oven has elements above and below the sheet so I've assumed the surface temperature on both sides is the same.
Hello
I've been asked to provide an estimate of the core temperature of an ABS plastic sheet heated in an oven during a thermoforming process.
I have no real knowledge of the heat input to the sheet, but I do know the skin temperature is 165-175 celsius after 180s of heating.
My question is...
