“Visando adequar a mesma qualidade que tínhamos na co-extrusão de 3 camadas, optamos em retirar o sistema que tínhamos na co-extrusão de 7 camadas e adotar o sistema da Octagon que já era conhecido e utilizado por nossa empresa há mais de 10 anos. Após visita e esclarecimentos técnicos, resolvemos atualizar o sistema que já possuíamos. Hoje, com os sistemas da Octagon, atingimos uma qualidade excepcional em nosso filme e comprovadamente um aumento de nossa produtividade, pois também adotamos os softwares de gerenciamento.”
What is SmartLip?
SmartLip is an air ring for automatic control of the thickness profile of blown film.
Reducing tolerances by up to 70%, this special air ring ensures optimal properties for the manufacture of technical films. In addition to standardizing quality, it reduces production cost and increases extruder production capacity by up to 30%.
Why use SmartLip in your company?
The unique difference of the SmartLip DL air ring lies in its mechanical design of the automatic control of the air flow where control elements position themselves automatically.
The process of thickness profile correction in the SmartLip air ring is achieved by internal movement of the elements that control the zones of the cooled airflow.
This gives the edge over other systems for better control of geometry, bubble stability and thickness profile correction.

Capacitive sensor for measuring thickness profile
Octagon offers several sensor models for thickness measurement. All of them can be connected to the SmartLip Air Ring for automatic thickness profile control.
Upon activating the system, the sensor starts to measure the thickness variations around the film. After completing a full rotation of 360º, the thick and thin spots of the profile are identified.
With completion of each sensor rotation, a complete thickness profile is displayed on the computer screen. Simultaneously the automatic air ring receives the information where the thickness variations need to be corrected.
Increase in production
How can increases in production be achieved with the SmartLip TL air ring?
1st. The internal airflow distribution is uniform reducing the risk of bubble collapse to a minimum. This allows the operator to “pump” more air during the process.
2nd. The automatic adjustment of mechanical settings allows the operator to make fine adjustments.
3rd. With the air flow being automatically controlled the operator is able to accelerate the extruder. Example: an extruder without the automatic air ring has an operating limit when the balloon starts to wobble (flatter). With the SmartLip air ring the bubble begins to flatter at a later point due to special design of lipset and the operator can make fine adjustments while accelerating the extruder. In parallel he can follow the thickness variations on the monitor.
4th. In the Triple Lip model the third air outlet “pre-cools” the hot melt coming out of the head, allowing the operator to increase the extrusion capacity without losing neither bubble stability nor the mechanical properties of the film such as shrinkage, brightness, etc.
