Does anyone know about this strange process?

In Dutch, but pretty self explanatory. You can use bottles, ore shrink-wrap. What could work as well is some flat sheet of clear plastic, like the back of a blister pack, heat it up, and pull it over the mould.

Ahh, ok. So you heat it up to melt it into shape. Just use any old kind of plastic. Thanks.

About materials: If you know any high school teachers, or ask an unfamiliar one nicely, you can ask them if you can take the rolls of sheet acetate they use for their projectors once they're done with it. Most teachers, especially math teachers, who go through them really quickly if they don't use whiteboard, usually throw them away instead of bothering to wash them.

PS forgot to mention that reusing acetate would probably be good for stencilling, too. I'm a packrat, and I'm sure there's others like me on /po/, and there's a kajillion uses for stuff like that if you're into handicraft and/or DIY projects.

Or an art major. You would not believe some of the uses I know of for acetate. One of the more interesting uses is to take a sheet of colored acetate and use it to find out how much grey is in colors. The teacher suggested red acetate, but the problem with any color acetate being used for this is that whatever color it is, it will not work on that color.

Now if I can ever come across some colored acetate that someone else has thrown away. You would not believe what awesome stuff can be made from what people throw away.

This is basically a simplified form of vacu-forming. You can use clear styrene sheets (found in most RC and Hobby stores), acetate transparencies (available at office supply stores), or the PVC-based packaging. Styrene is the easiest to form this way but the clear styrene is very brittle. Acetate and PVC take a lot more heat to form properly, so you want to make sure you're using something that can take the heat when you make the "plug" (the part you're forming the plastic over).

I may sound like a noob, but I'd like to know, how hot should you heat it, and by which means, to obtain such results?

(damn, we need a /hc/ for handycraft ... well, maybe /hc/ isn't really the best board name...)

I recommend using blister packs, either the back side, or even the boxy side itself. Make sure your piece is longer and wider than the base of your plug. It is good to have a frame around the soft, heated part so you can pull it down. If you use the box, you can use the rest as a frame, or if you have a flat piece of plastic, make a frame from some scrap wood.
A heat gun is great as you can control the temperature and you can apply the heat evenly without burning holes.
When the plastic begins to sag, and maybe even wave from the air flow, it should be okay. Just pull the frame down over your plug. As long as you dont rip it, you could even reheat it, and try again, only then watch out for creases.
One more tip: Make sure your plug is elevated and fixed on your workbench, so you can pull the frame down far enough (below the plug itself).

so what would you make the plug out of i was thinking you could use some kind of modeling clay that could be fired but i don't really know

If you're using something like styrene that melts at a low enough temperature, you might be able to get away with Sculpey (you'll want to coat it with something to keep it from bonding to the plastic, though). Otherwise, use epoxy putty, polyester putty, or some sort of resin that is fairly heat resistant.

Interesting. Could you tell me more? If you don't want to derail the thread, please email.

Thanks :)

Not any old plastic. Number 6 recyclable will shrink with heat - it's the same sort of plastic "Shrinky Dinks" are made from. You can shape the stuff once it shrinks. Usually this plastic is found on bakery containers (like plastic cookie boxes and stuff.)

I'd suggest acetate sheets, like others in the thread.
