I experimented with vacuum forming inserts a few years ago, I found that you need to drill a number of small holes in the form to draw the plastic down tight.
Look on the underside of the insert and you will see little raised bumps formed when the plastic sheet was drawn into the holes, that's what I duplicated on my form. I figured whoever designed the factory form must have already worked out the ideal pattern and hole size.
I had planned to make a go at mass producing them, but my day job just kept getting in the way to devote the time to finalize my setup.
