Re: A good melting polymer

Thank you very much for answering.

This is the initial condition before melting.
___________
___________  <--- Hot Plate
    ___
    | |
    | |      <--- Cylinder
    | |
|   | |    |
|___|_|____| <---- Circolar box


This is the desired final condition: moving the hot plate towards the
head of the cylinder, it melts, pours in the box and fill it.
___________
___________  <--- Hot Plate
 __________   
|          |
|__________| <---- Circolar box now filled with the melted cylinder.

I hope that I have made my self more clear this time :-)

I would prefer to search among commercial available polymers first.

Thank you very much again.

I'll keep your message.

Regards,
Ruggiero
