Soft PVC Braided Hose Extrusion Line
The Soft PVC Braided Hose Extrusion Line is engineered to manufacture high-performance PVC braided and steel-wire reinforced hoses. Utilizing stable plasticizing technology and precision braiding systems, these hoses deliver exceptional flexibility and durability.
Featuring a three-layer composite structure—a soft PVC inner tube, a reinforcement layer of polyester fiber or steel wire, and a protective PVC outer coating—the hoses perfectly balance flexibility with mechanical strength. This robust construction ensures outstanding abrasion resistance, pressure resistance, and chemical resistance.
Consequently, these hoses are extensively utilized in demanding environments such as gardening irrigation, household water supply, industrial fluid delivery, construction sites, food processing, and medical equipment.

Advantages of Soft PVC Braided Hose Extrusion Line:
Exceptional Plasticizing & Structural Integrity – At the heart of the line lies an optimized screw design that guarantees superior PVC plasticizing. This ensures uniform wall thickness and consistent quality. Coupled with high-speed precision braiding, the hose achieves remarkable pressure resistance and tensile strength, forming a durable composite structure ready for demanding environments.
Precision Shaping & Automated Efficiency – The process utilizes stainless steel cooling tanks to maintain perfect roundness and diameter stability, resulting in a flawless surface finish. Downstream, a fully automated cutting and winding system handles custom roll lengths with ease, drastically boosting production efficiency while lowering labor intensity.
Robust Build with Premium Components – Durability is paramount. The screws and barrels are crafted from high-strength 38CrMoAlA alloy steel with nitriding treatment for extended service life. We integrate world-class electrical components from SIEMENS, OMRON, and SCHNEIDER to ensure the entire line operates with long-term stability and reliability.
Smart Control & Energy-Saving Design – Operated via an intuitive PLC interface, the system manages tension adjustment, braiding synchronization, and real-time fault alarms, significantly reducing manual intervention. Furthermore, the optimized mechanical design minimizes energy consumption without compromising high-speed output, effectively reducing your overall production costs.
Flexible Configuration Options – To meet diverse market demands, the line supports modular upgrades, including co-extruders for multi-layer structures, stripe marking units, and high-speed braiding machines, allowing you to customize the equipment to your exact specifications.
Working principle of Soft PVC Braided Hose Extrusion Line:
Inner Layer Extrusion
A high-efficiency single-screw or twin-screw extruder uniformly melts PVC material to form a smooth, precise inner tube. Optional co-extrusion technology enables the production of advanced multi-layer structures for enhanced performance.
Reinforcement Braiding
A high-speed braiding machine accurately wraps high-stensile polyester fiber or steel wire around the tube, creating a dense mesh structure. This critical step dramatically increases pressure resistance, tensile strength, and anti-burst performance.
Outer Layer Extrusion
The outer PVC layer is extruded and tightly bonded over the reinforcement layer, delivering a seamless, wear-resistant, and visually clean surface finish that protects the hose from external damage.
Cooling and Shaping
Passing through a stainless-steel vacuum cooling tank, the hose is rapidly stabilized to maintain precise diameter tolerance and prevent thermal deformation.
Haul-off, Cutting, and Winding
A heavy-duty haul-off unit provides steady traction, while an automatic cutter and winder execute precise length control and neat packaging—maximizing production efficiency and minimizing labor costs.
Centralized System Control
The entire line operates under a centralized PLC intelligent control system, ensuring perfect synchronization across all sections. This guarantees stable output, uniform hose dimensions, and consistent surface quality.
