A highly specialized co-extrusion line producing extreme-durability suction hoses (commonly known as "ox-tendon hoses"). This PVC spiral reinforced hose making machine integrates a rigid PVC spiral skeleton inside a soft PVC wall for heavy-duty industrial ducting, agricultural pumping, and powder conveying.
Utilizes two separate extruders simultaneously in a right-angle configuration: one for the hard PVC structural spiral, and another for the highly flexible soft PVC outer body.
Creates crush-resistant, kink-proof hoses that are essential for severe environment applications including heavy-duty water suction and ventilation duct systems.
Features a specialized 3D-adjustable rotating mold utilizing rust-proof stainless steel springs to flawlessly wrap and bond the soft wall around the rigid inner spiral.
Engineered for continuous, high-yield production with absolute material integration.
Configured with two single-screw extruders positioned at a precise 90° right angle. Features optimized screw designs for distinct rigid and soft PVC processing, ensuring exceptional plasticization and high yield.
Advanced internal flow channels compress and merge soft and rigid PVC seamlessly. Fully polished and electroplated interiors prevent material sticking or burning, establishing a highly stable extrusion base.
Driven by robust sprocket and gear transmission with full 3D adjustability (X/Y/Z axis). The forming mold utilizes stainless steel springs, offering excellent flexibility and absolute rust resistance for a prolonged lifespan.
A massive 30-meter cooling unit forged from premium 304 stainless steel to guarantee rapid and thorough material cooling. Features a smart detachable modular design for highly efficient shipping and easy onsite assembly.
