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

A complete IBC "piece" or system typically includes several integrated parts:

Numerical Study of Internal Bubble Cooling (IBC) in Film Blowing INTERNAL BUBBLE COOLING

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:

Modern systems, like those from Addex Inc. or TSM Control Systems , use ultrasonic sensors to monitor the bubble's diameter. These sensors trigger automated blowers or valves to maintain a perfectly stable size. Core Components The numerical results suggest that Internal Bubble Cooling

A dedicated exhaust pipe, usually located in the middle of the die, pulls the warm air out.

As this air touches the hot plastic (molten polymer), it absorbs heat. IBC systems add a sophisticated air-exchange loop inside

Fresh, often chilled air is blown into the center of the die to inflate the bubble.
