Friends, this may seem a very basic query but if I had the answer, I
wouldn’t be asking.
When I’m heating a sheet of polypropylene or PE for any drape and vacuum
moulding, the sheet invariably ends up with air pockets between it and
the teflon oven sheet I use. Of course these air bubbles then translate
to the outside surface of the finished orthosis as lines on the finish.
This is a minor detail but one that would/should obviously be better
done without in terms of professional finish. What am I missing? What
have I forgotten from school? Please teach this shamefaced P & O.
