Vacuum Forming

Locating Stock

Polystyrene seems to be the stock of choice?

Locally

I haven't bought plastic in a while but generally these guys will sell to walk-ins. Scrap from sign shops used to be a good way of getting stuff to mess with, not sure if it isn't all recycled these days.

Process

• Heating the sheet in an oven for 10-20 min. at 100 degrees will dry it out and helps make the form.
• A heat gun while drawing the plastic down over the mold is an enormous help.
• There should be a book in the library on vacuum forming that might help a bit.
