Prepping your Work Area

Heat up the oven (450 degrees Fahrenheit, 232 degrees Celcius) on the bottom burner . Do not use “preheat” (the top burner burns plastic and heats up the BACK plastic too quickly)

Position the plaster mold on the vacuum table. You can learn how to make plaster molds in the Casting Plaster Molds section.

Place a sheet of cut styrene on the frame.

Tape the edges down to ensure no slippage during the vacuuming.

Place the other frame on top of this one and lock the two together.

Test the vacuum-form machine and make sure a good amount of air is being sucked into the machine. Do not allow the plaster cast to obstruct the vacuum hole as it will hinder the vacuum-forming process.

You want air to go into the hole so that the plastic will be VACUUMED onto your plaster cast. Use small chunks of wood to keep the plaster off the hole, if need be.

Now lets heat the plastic
