Internal Bubble Cooling May 2026

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

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 INTERNAL BUBBLE COOLING

Fresh, often chilled air is blown into the center of the die to inflate the bubble. A dedicated exhaust pipe, usually located in the

Numerical Study of Internal Bubble Cooling (IBC) in Film Blowing These sensors trigger automated blowers or valves to

As this air touches the hot plastic (molten polymer), it absorbs heat.

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

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