Pressure forming involved forcing a hot plastic sheet against a mold
by introducing compresses air to the sheet's outer side. ThermoFab,
the leading thermoforming provider, recommends pressure forming when
your custom plastic enclosure requires features that cannot be achieved
by vacuum forming alone.
Pressure-formed parts compare favorably to injection-molded
parts. For smaller volume runs, pressure forming offers injection-molded
quality and details. The pressure applied (up to 100 pounds per square
inch) is approximately five times higher than with vacuum
forming, which makes it possible to obtain highly detailed parts
and textured finishes.
Pressure forming uses air pressure to achieve an unparalleled level
of detail on the mold side and a higher quality finish that leads
to sharp edges, undercuts, and other close tolerance details. The
end result? You receive a product with the look and feel of an injection
or structural foam molded part.
