For vacuumforming, I use medium sized sheets of plastic sandwiched between two wooden frames and heated in an oven. These sheets of plastic will for formed over a mold on a vacuum table. STYRENE and ABS are the types of plastic sheets that I use to vacuumform parts with.

Styrene is also know as “Polytyrene” or “HIPS” (Hi-Impact Polystyrene).

ABS stands for Acrylonitrile Butadiene Styrene. It basically a form of Styrene plastic with an added elastisomer.

Styrene usually comes in a matte color, heats up easy in an oven, and takes paint very well. But, styrene is not as flexible as ABS plastic.

ABS plastic comes natually glossy , and flexes well under pressure without snapping or breaking as easy. Paint has been known to flake off the surface over 10 or 20 years time if flexed and used enough.

I recommend you using styrene if this is your first time vacuumforming. ABS plastic does not heat up as evenly as styrene, and hot spots in the heating process can ruin a vacuumpull. Using the easier to use styrene will save you time and money in the long run if this is your first time vacuumforming.

Buy the sheets of plastic from a local plastic supplier. I use www.gepolymershapes.com as my supplier. They cut the plastic to size and ship directly to my door. You can purchase styrene or “polystyrene” in an .080 gauge (OH-eight-gauge) thickness, or a glossy ABS plastic in .090 guage thickness.

Cut the large sheets down to fit the wooden vacuum form frame, and allow 1 -to- 2 inches of play on all sides. Notice that in the picture I have some EXTRA left over from the cutting . that is due to the fact that my Vac-frame is only 21 x 24 inches. I had to go with what fit in my oven. (grin)
