Bubble Cooling
Bubble cooling is one of
the major factors to
consider during the
extrusion process; the
introduction of the internal
bubble cooling system has
allowed considerable
progress. There are now
viable systems for precise
control of air temperature
for cooling the external air
ring.
Control of the air ring
temperature ensures that the
geometric shape of the
bubble, the "neck", the
"frost line" position and
the bubble's diameter is
maintained.
Benefits
Variations between day
and night temperatures,
typically 15 to 45șC, can
result in fluctuations in
output between 10% to 15%.
