Ok first of all, this term I know because I study urban design and refers to the joining of plastic pipes such as polyethylene, polypropylene, PVC, and other plastics, using heat and pressure. To learn more visit http://www.fullmecanica.com/u/union-de-tubos-con-termofusion
Here I apply a smaller scale with the accessories of plastic, if you started to use for errors that arose in several projects, but had no photos, nor the expertise to make a tutorial, until I made the costume of Bishamon and claws Hsien-ko.
WARNING: Do not use this technique if you have not read all the recommendations and use the necessary precautions so could cause injury or fire. Be cautious.
basically heating plastic to its melting point (more or less when this soft), not to be incinerated, just this soft and once this is done have to apply pressure and let it cool, that's all.
Now everything is not so simple, there are several aspects to be covered to prevent accidents (such as burn wounds):
How we heat the plastic? I have seen many tutorials on the internet where they shape the plastic in the heat of the stove, and good is an option, but wastes a lot of energy, I recommend you use a candle, its flame and not look down at its tip is about of 1100-1200 or C. [1] The second option is a lighter, which is the one used in the photos.
How should see the plastic melting point? For will simply softens, if a painting can be seen little dark, but this is by burning plastic colors, to avoid arguments, most of the plastic "thin" reach its melting point within 5 seconds of exposure to heat from the candle, and "thick" as PET, which reach to 10 seconds.
How long piece should be heated? Although parts which only requires a junction point have no problems, long pieces, require a skill a little faster, since it has to pass the flame, for the fusion line rapidly and continuously, about 7 seconds if it was timely.
How and to apply pressure to join the pieces? Initially use bottle caps, because their shape allows its use, like a paste and rub the spot or allow the fusion line, for a better finish, but then use my fingers, because the plastic does not as hot, just needed a little wet my fingers before rubbing the area to unite and avoid burn, also use tweezers. But I recommend the bottle caps.
Finally, remember that fire is a very dangerous if you use this technique to avoid having a flammable liquid near the candle can put you on a piece of cardboard, so that will not stain anything, do not want to bother with us, avoid working on carpets, beds, sofas or any combustible surface.
Above all do not bring his face to the fire, the heat can burn the eyebrows, eyelashes or hair. When finished using the candle turn it off. Be cautious and if they are under age, ask an adult for help, beware, the most valuable tool we have is the body.
