Functions of Hose Mandrel in Rubber Hose Production

1. Sizing & Shaping: Acting as the inner mould, hose mandrel defines the hose's inner diameter, roundness and straightness to ensure consistent dimensions.

2. Body Support: Hose mandrel supports the inner bore during winding and vulcanization, preventing collapse, deformation and inner wrinkles.

3. Smooth Inner Surface: Hose mandrel's sleek surface delivers a flawless inner bore, optimizing fluid flow performance.

4. Process Assistance: Hose mandrel facilitates winding of steel wire/textile reinforcement and applying outer rubber layers, enabling tight lamination and reducing air bubbles and delamination.

5. Demoulding Reference: Hose mandrel is extracted after vulcanization to complete hose forming, serving as a key tool for continuous production.
