Our factory is equipped with professional circular sewing machines, which boast beautiful appearance, smooth interior, and fine workmanship, with a lifespan of over a million uses. Supported by an inner steel wire frame, they are flexible, non-deforming, and resistant to friction. Made with wear-resistant industrial canvas, they offer high cost-performance and have received positive feedback from our customers. They feature compact structure, ease of use, high distribution efficiency, and dust-free loading and unloading. They are not only used for automatic or semi-automatic unloading and loading of cement in storage facilities for cars, trains, and ships, but also for the bulk distribution of materials like coal powder, stone powder, aluminum powder, and food powders.

Flexible hinged joints can be used horizontally or vertically. When used horizontally, they are typically made with a support ring process, which ensures a uniform distance between the sleeve interior and the cylinder, reducing friction and extending service life. When the stretch length is great, a metal ring can be added at each fold to enhance the stability of the sleeve. Installation methods are not restricted; they can be fixed with a flange or with a collar band.
