Internal Bubble Cooling 〈2025〉

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

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

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: is a specialized air-management technology used in blown

A dedicated exhaust pipe, usually located in the middle of the die, pulls the warm air out. or TSM Control Systems , use ultrasonic sensors
