I have a suspicion you posted this for the coffee-cup contest, but it's no good as an entry as the cups must be paper.
Also you need to actually do something and post photographs, theory and internet-images don't make an Instructable.

I am not sure I can see how "liquid" this process would be. The best I have ever seen melted Styrofoam is the consistency of marshmallow cream. I would love to see some form of pictures on this.
Also, I know that the fumes from melted Styrofoam are dangerous and can lead to some serious health issue even from limited (few minutes) exposure.

thars why we use safety gear :] apron, googles, gloves,respiorator , and a face shield if you got it.
btw for the foam problem: this is why you have to vibrate the hell out of the stuff!

Better bet is to reduce the styrofoam back to the pellet form (hot pressure pot and agitation), then re-expand it in a new mold (heat at atmospheric pressure).
yea i actually figured out how to do this with a old pressure cooker. the problem was though is that when i got it out of the pot, it ruined the gasket on the pot so it was a major bummer:( but i plan to get my hands on a better system to do this,
Mmm the lack of action pictures suggests this may be a theory only.
1. The styro foam when melted tend to give off cyanide gas.
2. The resultant plastic will not remain foamed when reheated so the package will be thin and insubstantial.
3. There isn't any detail about how to make the mould. How do you get the melted styro-foam to coat the insides?
4. What release agent should you use to get the plastic out again?
5. What about forms with under cuts?
I don't think this is practical. If you wanted to make such containers vacuum forming would be much easier and there are lots of detailed instructables on how to do this.
On a positive not broken up styro-foam cups make great packing beads for your delicate things.

yes, you are correct about the fumes, but this is why i recommended this done out doors, with a resporator! also the mold making is really specific to your application. this is best for when you have to only make one part!. (as the mold is essentially destroyed in the process)
