Precise stable air pressure is a critical component in the extrusion of small plastic tubes. A precision internal air adjustment is needed for sizing and structure in the free extrusion of tubing. The outside diameter can be maintained for a wide range of varying flow rates such as when a cut is made or the tubing coiled.
MicroAirs provide air support through the pin inside the die to maintain the tubing’s shape and prevent a collapse during the extrusion process. Used to make single-lumen, multi-lumen, balloon, taper, catheters, automotive and medical tubing.
