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
As this air touches the hot plastic (molten polymer), it absorbs heat. INTERNAL BUBBLE COOLING
Numerical Study of Internal Bubble Cooling (IBC) in Film Blowing Modern systems, like those from Addex Inc
Fresh, often chilled air is blown into the center of the die to inflate the bubble. Core Components As this air touches the hot
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
A complete IBC "piece" or system typically includes several integrated parts:
