Our factory is equipped with professional circular sewing machines, which boast aesthetically pleasing appearances, smooth interiors, and meticulous craftsmanship. They are durable, capable of over a million uses. The lining with steel wire frame provides flexibility, resistance to deformation, and friction. Made with abrasion-resistant industrial canvas, they offer high cost-performance ratios and have received positive feedback from numerous customers. They feature compact structures, ease of use, high distribution efficiency, and dust-free loading and unloading. They are not only used for the automated or semi-automated unloading of cement 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.

The flexible and expandable coupling can be used both horizontally and vertically. When used horizontally, it typically employs a hoop-type manufacturing process, ensuring a certain uniform distance between the sheath and cylinder, reducing friction and extending service life. For greater stretch lengths, a metal ring can be added to each fold to enhance the stability of the sheath. Installation and fixation methods are unrestricted; they can be flange-mounted or collar-fastened.
