RE: [Inventor's club] Melting Plastic

Hi,

yes the vacuum cleaner is just fine and hair dryer can do the job as
well.
infact i dont want to use coal.. it is hard to work with it plus dirty.
it is ok in melting iron because iron melts in 1600 C. and aluminum in
660 C. and iron has carbon in it and it improves mechanical properties.
so the impurites of coal dont effect iron. but i want to just melt
plastic coke bottles. they have lower melting point. the problem is
how..
By the way what about the oil drum? it is steel as well.. didnt it melt
or have you coated it up with isolating material?
i thought about using kitchen oven or make something using electrical
heaters parts.. what do you think?

By the way i would wanted to include another mail message and my reply
for it..
=====here======
First i would like to thank you about the warning.
What i meant was the plastic coke bottles.
I visited a iron-casting company and seen that they cast iron by
following method:
they place the model they want to produce in a box, and fill with sand.
and they cut the top half of the sand box, take out the model. so there
is a gap in the sand box having the shape of the model along with some
entrances. and they melt the iron at 1600 C . fill the box with
melted-iron, so the iron gets the models shape in sand. they wait for it
to cool off.. and after that they clean the iron from sand and they have
the product.

So i thought i could use the same thing. with lower melting point
material: plastic. that is the whole story. they melt the iron in a
furnace, every body are near the furnace and breaths it. and they dont
only add pure iron to melt. the junk iron that they place to reduce cost
contains plastic junks as well. but since iron is more dense then
plastic , it floats over iron when they both melt and they add a special
collector, and separate the slag phase. so, people work to get off the
slag phase from the melted iron smoke the air.

And in hot melt glue guns. they melt silicon like thing. are they
harmful to breathe as well?

Well.. maybe you meant burning plastic is toxic instead of melting? or?
well.. im just trying to imagine and understand how toxic it could be
when melted...

Are you sure you mean "Can's" and not bottles???

Firstly I'd like to give you a friendly caution
regarding the melting of any plastic! IT IS HORRIBLE
TOXIC!!! You will need to take serious precautions not
to inhale or pollute the area your working in and
unless you have special ventilation or other seriously
costly industrial equipment, I would not be doing
anything like this at all!

What is it your trying to achive? You might be able to
accomplish the same thing faster and cheaper by
aquiring the pre processed materials without
endangering yourself or others! I would seriously
recommend that you investigate this to the "INTH"
degree before you carry it out. Others will likely try
to talk you ut of it!
