fiberglass is cooled, we remove it and start
preparing it for the hot tub structure.

To
make the acrylic finish of your hot tub, we will
put a sheet of the Acrylic into the Hydraulic
Clamping Frame and place it in the Vacuum
Forming Machine. We heat the acrylic sheet to
395° Fahrenheit until it is semi-molten. 
The
molten acrylic sheet is then stretched over a
vacuum mold. As the acrylic sheet sags into the
form we apply a vacuum to the underside of the
sheet and it vacuums it into the form of the
mold of the hot tub.
