I just picked up a Mattel Injector toy injection molding machine. Does
anyone have any idea what plastic resin was used in these? Google hasn't
turned up much so far.

Also do a Google search of the newsgroups. I just did, and there are
some threads from RCM that showed up. One suggestion was milk jug
strips, another 35mm film canisters...

Thanks - I'd tried Google Groups but missed those. More creative search
strings are in order, it seems.

[I've got one of those; it's basically a piece of junk. It's supposed to
work with regular styrene plastic, the type that airplane models, etc. are
made of. Probably the easiest thing would be to recycle some kid's toys for
material; just chop them into pieces small enough to fill the melting
chamber. But it doesn't work too well; the heater's inefficient and the
pressure (from leaning on a lever) insufficient. I couldn't get the
(supplied) molds to fill completely; maybe another thermoplastic would have
worked better, but I gave up in disgust...]

The resin used for the Mattel molder was of course sold by Mattel as a
refill and is probably not available. It was a very low melting point
material more like wax or sort of in between wax and plastic. An item
called "Friendly Plastic" by Amaco® would probably work, as it softens
in hot water; quite expensive however. I've seen it and other brands on
ebay, so you might do a search. It is also available through some craft
suppliers. A low density polyethylene might also work as it molds very
easily with minimum heat and pressure. Some jewelry waxes would also
work but are not very durable.

Good luck,

Good luck,
My brother had some of this wax/plastic mix when I was a little kid.
It was weird enough compared to either wax or plastic that even a 7
year old (me) could figure out it wasn't either but a combo of the
two. It was very weak compared to styrene but stronger than wax.

If you don't care about the color you could try hot melt glue. Probably
would need to coat the molds with a release to prevent sticking.
