Although hair driers and heat guns may be cheap to buy, its a pretty inefficient way to heat it and so the cost of running them long enough to heat the entire mold may end up costing much more, and no way to control the exact temperature (which depending on your epoxy may or may not be critical).
Heat blankets are expensive to buy, but PID controllers are cheap, and then you get very accurate heat control, to as high a temperature as you want (within reason)

cheap option for moderate heat that is semi controlled is seedlig heat mats with a thermostat. see my set up at: http://www.flicker.com/photos/rfa2009
i was able to get and maintain 105deg F for the entire pressing.
heat guns & hair dryers w/ ducting will be a pain, wont heat evenly, and be noisy as hell

Agree that using hot air is just wrong.thefreshpimpofbigair wrote:...

I also think that 105F is practically useless. Read question #1 in the Ski

With so much invested in ski press tooling and materials, what's a couple hundy more for an MEI heater blanket? Using high temperatures to cure and post-cure bake your skis will make all the difference in their durability. I cure at 190F and my skis keep their camber and maintain great "pop" energy, even after 40 days on the mountains, Wasatch of course!

yeah, that was him...but he built it himself "ghetto style"
mine is a standard product used in industrial heating applications.
width is about 59cm, it's supposed to reach 90°C at 100V (at least thats what the letter that came with it says) and the max. temp is 130°C.
only downer is that we have to wrap it in plastic ourselves since it's not isolated...shouldn't be a big problem though.
as i said, first tests will be held in may.
if they're successful i might be able to place a group order...i guess there's a couple of people here and at grafsnowboards that would love to have a less cost intensive alternative to their silicone blankets.

can you provide some more info on your heaters?

i'll do an in depth description as soon as i find the time to do so...one thing i can tell you already is: they work! tested them on a ski and they heated the press to 180F in no time.

Hi
I want to talk about profesional heating group in ski,snow,kite industry.
I can see on this youtubes videos that the wire go to the aluminium plate in one side and out in another side. I think that is hot water vapor or something like that.Quastion is how looks like this plate and how this hot vapor moves in that thin aluminium plate. Maybe someone see on reality this item.
