Decoiler

Product Overview

Xinnuo’s newest Automatic Hydraulic Decoiler is engineered for demanding roll‑forming workflows, featuring coil handling capacities of 5 T, 10 T, and 15 T, with options for heavier loads. Coil widths up to 1,250 mm and material thickness from 0.3–0.8 mm are supported. Fully hydraulic drive enables seamless integration into high-efficiency production lines.

Hydraulic Unwinding & Dual‑Mandrel Flexibility

This unit includes an automated expansion mandrel that grips the coil solidly and releases safely—enabling forklift‑assisted loading. For advanced setups, dual‑mandrel (reversible) versions allow rapid switching between coils without interrupting production, minimizing downtime.

Precision Tension & Feed Control

Equipped with PLC logic and hydraulic braking, the decoiler precisely regulates unwinding tension and synchronizes coil feed with downstream roll forming speed. This avoids slack, slippage, or abrupt feed interruptions—ensuring consistent metal strip flow.

Heavy‑Duty Build & Safety Features

Constructed with a rigid welded frame and robust base, it withstands the stresses of heavy coils. Additional safety mechanisms—such as outward-facing roll holders and shock absorbers—prevent recoiling hazards. Some models have optional water-cooled brakes for extended high-speed operation.

Operational Performance

Typical decoiler feed speeds are rated between 10‑15 m/min, depending on coil load and line integration. Hydraulic motor systems (often 3 kW) paired with efficient gearbox mechanisms ensure smooth torque delivery.

Application Scenarios & Advantages

Ideal for roofing, siding, wall cladding, and sandwich panel production, this decoiler helps streamline continuous coil feeding—especially on long shifts with multiple coil changes. The reversible and automated loading design significantly improves throughput in high-volume environments.

Customization & Support

Xinnuo offers configuration flexibility—such as track-mounted decoilers for serving multiple forming lines, varied arbor diameters for different coil sizes, and upgraded control panels. International CE/ISO certifications and a full year warranty with follow-up service ensure reliable global deployment.

Summary

Xinnuo’s advanced Automatic Hydraulic Decoiler blends hydraulic mandrel automation, dual-spool capability, PLC-managed tension and braking, and high build quality. It delivers efficient feeding, fast coil switching, and robust safety—rendering it a critical component of modern high-throughput roll forming systems.
