PUT ON GLOVES!

Turn the Heat Gun on.

Open the oven when it is ready

Slide the two frames and plastic into the oven and make sure that the frame will stay put.

You do not want the frame to fall while the plastic is heating up (a frame holding rack maybe necessary).

Close the oven door.

If the door will not close all the way, use the heat gun to “heat” up the side nearest you during the heating process.

As the plastic starts to warm up, it will begin to warp into a wavy shape. Do not be alarmed. This is normal. The plastic is just becoming soft in different areas as it heats up, and this causes warping. The plastic will go back to a flat surface as the entire piece evenly warms up to an equal temperature.

Once the plastic starts to sag in the middle by about 2 inches, prepare to get the plastic out. Open the door and start pulling the frame out of the oven.

Once the sagging reaches a certain point, it will sag faster. It is imperative that you catch it at the right moment. TRIAL AND ERROR are your allies at this stage.

Try to heat the plastic as evenly as possible. See the droop for a good vacuuming. I stopped it here for demonstration. IF you had a Professional vacuumform machine… this droop would not be needed.

Trial and Error are the key. Do not get too upset if the first 8 or 9 go bad.

Once the plastic is sagging by 3 inches, pull out the frame.
