As the melt moves up from the die the flow is directed and cooled
by an air ring for external bubble cooling.
The Eliminator Air Ring The Eliminator provides
·
adjustable primary orifice
·
secondary cone with independently adjustable vents for
maximum flexibility in controlling bubble stability and
improving the cooling rate.
The Eliminator has proven to demonstrate
·
improved cooling efficiency
·
ease of operation
·
better lock-in over a wider range of operating conditions
which resulted in significant (30-50%) improvement in
gauge consistency
·
higher output rates (as much as 35%)
·
improved clarity
·
better roll geometry
·
lower blower speeds for quieter operation and less energy
consumption.
The Eliminator for all materials including LDPE, LLDPE, mLLDPE, PP,
PVC and all coextrusion structures containing PA and EVOH.
UNI-FLO Dual-Lip Air Ring
The
UNI-FLO Dual-Lip Air Ring delivers two air streams from a common chamber
to the exterior of a blown film bubble
·
a gentle stream pre-cools and stabilizes the bubble
as it expands upwards along the forming cone
·
a high velocity, high volume stream draws the partially
cooled bubble radially outwards. This action thins the
melt stream to improve thermal conductivity.
