2021-04-29

A spiral protective sleeve is a helical‑shaped cover manufactured from materials such as polypropylene (PP), polyethylene (PE), or nylon (PA) using a hot‑state winding and extrusion‑forming process. It serves as a modern alternative to traditional metal spring protectors used for hose protection. Other names for this product include spiral protective sleeve, hose protective sleeve, and wire protective sleeve. Spiral protective sleeves can be produced using reinforced nylon, modified PE, and other plastic materials. The manufacturing processes include extruding sheet material followed by helical winding, or extruding tubular material and then forming it through rotary cutting. Hebei Shuangda Rubber & Plastics Machinery Co., Ltd. is a modern enterprise integrating research, development, production, and sales of complete sets of extrusion machinery for rubber, silicone, and plastics. The company’s main products include rubber extruders, rubber hose extrusion lines, three‑layer composite sealing strip extrusion lines, silicone sealing strip production lines, plastic sealing strip production lines, plastic profile production lines, plastic pipe production lines, elastomer extruders, and various other extrusion equipment. Additionally, the company provides production equipment for engineering seals, automotive seals, wire and cable applications, air‑conditioning hoses, braided hoses, automotive hoses, waterstop strips, and related products.
