Revolutionary Two-Stage Integration: Unlike traditional conduits, the COD process first extrudes high-clarity Silicon Core Sub-Ducts, which are then bundled and seamlessly encased within a heavy-duty corrugated outer jacket. This turnkey technology ensures maximum cable protection and zero friction for long-distance 5G and fiber optic deployments.
Utilizes silicon-core inner tubes to reduce friction by 70%, allowing for effortless fiber pulling over kilometers of network.
Bundles up to 7 sub-ducts into a single corrugated profile in a single pass, saving 60% of site installation labor costs.
Precision-engineered rotary forming and high-torque co-extrusion guarantee compliance with the strictest telecom infrastructure standards.
A precision-engineered combinational extrusion system optimized for advanced telecommunication conduits.
Driven by a 22kW AC motor (Frequency Inverter motor) and Delta inverter. Features a 38CrMoAla nitrided screw and Omron temperature controllers for robust, continuous production of the outer corrugated duct.
Forged from tempered 40Cr mold steel. Features mica heating and copper sizing molds for specific pipe diameters of 50mm-160mm, ensuring non-stop encapsulation of inner ducts.
A heavy-duty vertical or horizontal forming unit with a rotary mold block system, compatible with 50mm-160mm specifications. Integrated with up to 8 core-pipe unwinding units for multi-hole duct combination.
Driven by a 4kW AC motor (ABB brand inverter), providing a precise tension-controlled line speed from 0-3m/min using rubber block pulling.
Features a 16N.M torque motor for manageability, rotary encoder for metering, and manage massive 1000m rolls. Winding diameter supports 50-160mm.
Utilizes a specialized Saw cutting way driven by a 1.5kW motor and Autonics metering brand for accurate, burr-free cuts on corrugated pipe.
Designed for managed unwinding of silicon-core inner ducts. Winding diameter supports 20-42mm and can hold spools up to 1000 meters.
Tailored for producing low-friction silicon core inner ducts (e.g., 28mm) with a dual-layer co-extrusion system (SJ-70/32 and SJ-45/30), achieving a combined output of 130+30kg/h.
Equipped with vacuum calibration,torque-controlled winding for massive 1000m+ spools, to ensure maximum core integrity, zero crosstalk, and long-term network flexibility.
