Once you have pulled out the frame, do not delay in getting the plastic to the vacuum-form table.

Push the frame down onto the cast on the vacuum-table. Do not go at an angle. You want to go STRAIGHT DOWN. If you push at an angle, you will stretch one side more than the other and this will cause that side to be THINNER . This is not what we want. PUSH STRAIGHT DOWN !!!

Once the frame is securely down, turn on the shop vacuum. If everything went right, the plastic will be sucked right down.

Use the heat gun on spots that are not fully heated or that cooled too quickly. Be careful not to heat the plastic up in JUST one spot. Try to heat up an area of about 10 inches in diameter. This will let the plastic suck down in a uniform manner.

Continue the vacuum for at least 1 minute. This should give the plastic enough time to cool down. Turn off the heat gun at this point, if you haven’t already.

Use your fingers to push down pieces that may need it. Be careful!

Watch out for the plastic BUNCHING up in spots. Notice how the plastic got sucked together at the sides. This happens for HARD corners. The only way to alieviate them is to have the mould a few inches off the table so that the plastic will have a BIUFFER AREA to suck down onto.

Turn OFF and release pressure from the vacuum once the plastic has cooled enough to remain rigid.
