Internal Bubble Cooling Page

is a specialized air-management technology used in blown film extrusion to increase production speed and film quality. By constantly exchanging the air inside the inflated plastic "bubble," IBC systems remove heat from the internal surface, allowing the plastic to solidify faster than with external cooling alone. How IBC Works

The numerical results suggest that Internal Bubble Cooling (IBC) equipment introduces distinctive design and operation challenges. ResearchGate Digital Internal Bubble Cooling - Addex Inc. INTERNAL BUBBLE COOLING

A dedicated exhaust pipe, usually located in the middle of the die, pulls the warm air out. ResearchGate Digital Internal Bubble Cooling - Addex Inc

In a standard blown film process, molten plastic is extruded through a circular die to form a tube, which is then inflated into a bubble. IBC systems add a sophisticated air-exchange loop inside this tube:
