The Sealed Ω-Shaped Vacuum Infusion Tube with Perforations is manufactured through precision extrusion using polyethylene (PE) and polypropylene (PP). It provides excellent structural stability, high temperature resistance, strong aging resistance, and outstanding anti-indentation performance. Its Ω-shaped design ensures that the tube maintains its geometry under vacuum pressure, providing smooth and stable resin flow during composite vacuum infusion.
This product is widely used in wind turbine blade manufacturing, as well as other composite vacuum infusion processes requiring durability and consistent flow channels.
