Good Afternoon,
We have measured temperatures of the positive plaster molds and the
heated thermoplastic prior to vacuum forming ankle foot orthoses.
The AFO positive plaster mold temperature is approximately 65 - 75 F,
and the heated thermoplastic temperature just prior to vacuum form is
approximately 350 F.
Do you ever preheat the plaster model to decrease this variance in
temperature?
If so, what method do you use to increase the temperature of the plaster
molds?
Heating blanket, oven at low temperature, etc?
Thank you for your time.
