Medical tube extrusion involves melting polymer resin and forcing it through a precision die to form a continuous tube. Internal air pressure is introduced to maintain the tube's inner diameter and wall thickness as it cools. MicroAir regulators precisely control this internal air pressure — even at ultra-low levels below 1 inch of water — ensuring dimensional accuracy and consistent quality throughout production.
