Guys your molds for pre -pregs made from : polyster resin, epoxy, vinylyster? or anything more? as i know polyster molds that lots of do they from polyster but that holds not more then 60 celcius.

and what i understood dont need to buy autoclave or to make it. simply need box metal with spirals that hold good heat inside and temperature sensor and controller. from outside sitting easycomposites vacuuming pump and vacuuming black color hose that hold   temperature and not melt.
