Pressure extrusion forces molten plastic through a shaped die while internal air pressure is introduced to support and size the tubing bore. An ultra-low air pressure regulator precisely controls this internal air, determining the tubing's outside diameter, wall thickness, and structural consistency throughout the extrusion run.
