Gemma Jane Posted July 14, 2009 Author Share Posted July 14, 2009 Don't be put off by glass temperatures and stuff. You don't need to know about this stuff to vac form. It's one of those things that in practice is more about feel for the material. I've heard it said that a complete novice will get it working after just a few attempts, I think that is about right.

Lindsay Todd Posted July 15, 2009 Share Posted July 15, 2009 Hi Gemma, good stuff. Back in college many moons ago, I did some vacuum forming. The preheat was like an old grill unit. I used to work in the domestic heating market and often we found the best way to develop an even temperature for a grill was to do a toast test. Yes you guessed it layers of bread all over the grill and see where the hot spots are and then you can make adjustments to the heat distribution. In our case these were ceramic tiles but the same applied to moving mesh in regarding to flame impingement. On deep drawn parts we preheated the mould, soft materials like wood or plaster benefit from the use of a hot air gun or similar. I'll continue to observe with interest!

Klippy Posted July 15, 2009 Share Posted July 15, 2009 Hi Gemma, I wondered about the peg board, not only does it allow air to pass through it. you can also have pegs on the back of your plug to stop it from moving. I've never seen one of these things in action, do you pre-heat your material in its holder and then drop it down on the vacuum box? Quote Link to comment Share on other sites More sharing options...
ERIC CLAPHAM Posted August 26, 2009 Share Posted August 26, 2009 Gemma , It looks like you are well down the line to success on your ownsome but just note that I have copies of two vac.forming techniques from the R.M. and R.C.M.E by Matthew Ivey and Robin Fowler .They were using low cost soft - drink bottle plastic and used a gas oven for heat . If you are interested.............................. About a dozen A4s in total . Rgds., Eric C. Quote Link to comment Share on other sites More sharing options...
Klippy Posted August 26, 2009 Share Posted August 26, 2009 Hi Eric, sadly after a serious disagreement with another member Gemma has left the forum. A great loss and most of us miss her! I wouldn't mind seeing these articles, perhaps I could PM you my e-mail address? Quote Link to comment Share on other sites More sharing options...
