    Generally we(Radicons) don't seem to melt existing plastics down for mold work and casting. Seems most of us are using two part resins in one form or another. That being said, I belive a plastic that can be melted down and formed is called plasticene. It comes in little beads and you can microwave it to melt it down. only used it once though, so my expertise iss very limited.

    Plastic used in Transformers is ABS. if you find anything made from ABS, that should be fine. Clear parts use Polycarbonates.

    There is no plastic melted in mold making.

    There are mold making kits, or seperate liquid plastic compounds that can be bought online or in your local hobby shop.

    Beings it sounds as if you are a beginer, I recomend you get a kit by "Smooth-on." "Mold making kit", and Smooth-on, Smooth Cast- 320." These kits are inexpensive (around $28.00 each) And the rubber molds can be reused many times (i have been using a few them still from about a year or so ago).

    They have a web site Smooth-On - Mold Making and Casting Materials for a World of Applications!.
    Check it out, and or google mold making for plastics. Alot of sites and others experiences are very informative. (Thats how I started out)

    Let me know if you need more help.

    I do not recommend you trying to use raw or recycled crushed plastic to do your replications. Very dangerous and unless you have the proper heating and extruder you will no doubt make a mess and get hurt.

    What you do want is a 2 part resin compound(Or Urethane Plastic). Macross gave you the best option and site for this. The Smoothcast 305 is your best bet to start out with if you want some good heads, weapons, etc...
