Internal Bubble Cooling May 2026

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

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

A complete IBC "piece" or system typically includes several integrated parts: As this air touches the hot plastic (molten

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 or TSM Control Systems , use ultrasonic sensors

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.
