Air Support for Extruded Plastic Tubing

MicroAir

The MicroAir provides high precision control of tubing outside diameter by regulating air pressure to a set point during the manufacture and extrusion of all types of profile extrusion for plastic medical, catheter, and automotive tubing. Our precision ultra low pressure air regulators are used for precise air sizing and ovality of extruded plastic tubing. Support air pressure control keeps the diameter variations during extrusion from occurring. Internal air pressure is applied through the DIE and is maintained constant for widely varying flow rates such as when a cut is made or variations in your process, etc. Multi-lumen tubes can be made using an air support for each lumen.
