Polyurethane coiled mandrel sleeves are widely used in industrial applications such as hose manufacturing, composite layups, and forming processes. Their flexible, durable design supports the internal shaping of rubber, silicone, or thermoplastic hoses during curing or extrusion. In aerospace and automotive composite fabrication, they maintain internal structure and allow easy removal post-curing. With excellent abrasion resistance, non-stick properties, and tolerance to heat and chemicals, these sleeves are ideal for demanding environments across industries like automotive, aerospace, medical, and oil & gas.
