The TDK-500 Insta Gauge Automatic Air Ring provides a reliable and effective solution for controlling transverse direction film thickness, which ensures uniform profile control on blown film extrusion lines. The TDK-500 auto cooling ring quickly puts production on gauge, on time, by using a re-envisioned approach to air modulated gauge control. See below how the TDK-500 Insta Gauge exceeds expectations in auto gauge air ring design and performance! Secondary lip air modulation for quick, precise auto profile control of the gauge Low pressure design to maintain maximum cooling ring efficiency and high production rates The TDK-500 improves on the implementation of airflow modulation for gauge control by using secondary lip air modulation where the velocity changes are more effective. Firstly, this leads to a quicker reaction time and higher control resolution than primary lip air modulation. Secondly this also fully permits the primary lip to achieve its job of holding a stable bubble by isolating the primary lip cooling from the gauge control air adjustments. Controlling transverse direction film thickness significantly reduces resin costs by only producing the required film gauge. It also simultaneously guarantees that thin spots do not effect the film integrity or processability. The air flow from each control zone is constrained in an independent channel that extends to just before the secondary lip exit. This eliminates zone cross mixing and provides a more direct and effective control response to the film for the best auto profile control (see orange zone, to right).
