Plastic vacuum formers are an important part of prototyping. If you need a nice plastic robot body, or custom case for a project you are doing, get your tools, 'cause this one's easy to build and fun to play with.
The vacuum former uses a simple concept. They use the power of a vacuum to suck gooey plastic sheets very tightly around an object you place in them, making a 3D copy of pretty much what ever you want.
Plastic vacuum formers are usually big, expensive machines; however we don't always need to make huge pieces for our projects, so these machines would be pointless to have, or at least that's what I tell myself so I won't want one ;)
Our molder will have a good size for most projects that you probably deal with. If you get confused or just want to see what I am talking about, watch this short clip showing the video of a vacuum form I made.
