I want to make a 5" diameter shallow dome using transparent Plasticard. This stuff is as clear as acrylic (Perspex). The material I'm using is 1mm thick. I'm making a Airbox with a removable plate that has a 5" diameter hole in it which determines the diameter of the dome. The dishing required is very slight, 1½" to 2" max. I gather that Plasticard softens at 80ºC. I have an airline which is fully variable from 0 to 120psi (up to 8CFM! LOL)
Question: Will it be possible to immerse in a container of hot water , slowly bringing up the temperature to 80ºC or more? Will it blow to shape at 80º or will it need to be 100º or more? Seems easier to soften using near boiling water than placing in the oven?
Advice please
