can you melt plastic into a mold like plastic water bottles and if you can how hot would it need to be and does it have toxic fumes or something?
You can melt plastic to make parts (injection molding) but water bottles actually start from a plastic tube that re-symbols a cigar tube and gets blown with air inside a bottle shaped mold (blow molding) and then you can heat plastic sheets to melting point and use vacuum to pull the plastic over a mold (vacuum molding) but yes all plastic smells and has toxic fumes when melted...theres also a plastic that looks like putty that you melt in boiling water to make it soft...you can mold it into any shape and when it cools it turns into a hard plastic...no smell and not toxic...
In short, with the plastics you're suggesting, no. It's like saying if you melt a car down, could you form another one? That answer is no because more than just heat was required to form the vehicle; The same goes for most plastics. You're probably associating the idea with candle wax which just requires heat to establish the form, so only heat is required to reform it; Same with many base metals. Most modern plastics are formed from a combination of heat, pressure and chemical reactions all of which would be need to recycle the unit into something new. Would need a lot more details but there is probably a better way to accomplish what it is you are trying to do.
