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.
