I. NE、Decoiler Machine Introduction

The Decoiler Machine (also referred to as Uncoiler Machine) is an indispensable primary equipment at the front end of any metal sheet processing or roll forming production line.

This machine is specifically engineered for:

• Heavy-duty loading

• Non-destructive uncoiling

• Smooth feeding of various metal coils

Applicable materials:

• Hot-rolled steel

• Cold-rolled steel

• Stainless steel

• Galvanized steel

• Aluminum

As a world-leading Decoiler Machine Manufacturer & Supplier, our advanced Steel Coil Decoiler Machine line integrates:

• Heavy-duty spindle bearings

• Hydraulic/mechanical mandrel expansion

• VFD-driven automatic loop-sensing control

Engineered to match high-speed stamping presses or heavy-duty roll forming machinery, our Automatic Decoiler Machine series ensures:

• Zero coil slippage

• Flawless material alignment during high-speed payoff

• Maximized feeding efficiency

II. Key Features & Advantages

1. Heavy-Duty Rigid Structure & Durability

• Base and cantilever mandrel made from high-strength premium steel plates and large-diameter solid forged shafts

• Stress-relief annealing and precision machining ensure zero spindle deformation under heavy loads (5–20 tons)

• Provides rock-solid stability and extended service life

2. High Efficiency & Automated Synchronization

• VFD-driven automatic loop-sensing control (photoelectric or ultrasonic sensors)

• Payoff speed synchronizes with downstream roll forming machinery

• Optional hydraulic coil car enables one-touch automatic centering and loading, reducing downtime

3. High Versatility & Wide Coil Adaptability

• Stepless mandrel expansion (manual or hydraulic)

• Handles various inner/outer diameters, widths, and materials

• Satisfies diverse production requirements

4. Low Failure Rate & Low Maintenance Design

• Core components (gear reducers, hydraulic pumps, electrical parts) from world-renowned industrial-grade brands

• Modular layout with centralized lubrication ports for quick maintenance

• Minimizes unplanned downtime

5. 100% Tailored Engineering & Customization Support

• Supports single-head/double-head configurations

• Optional pneumatic/hydraulic snubber arm or inverted-U support arm

• Customizable load capacities (3T–20T) and processing widths

• Fully tailored to factory layout

III. Strict Quality Control & Acceptance Process

1. Incoming Materials & Core Components Inspection

• 100% dimensional and non-destructive testing for structural steel, forged spindles, and bearings

• Hydraulic cylinders and sealing components pass IQC and pressure-retention tests

2. Mechanical Assembly & Mandrel Concentricity Check

• Precision dial indicators and laser alignment tools used

• Checks radial runout of main spindle, mandrel concentricity, and expansion parallelism

3. Circuit & Electrical Safety Testing

• Insulation resistance, dielectric voltage, and ground continuity tests

• Ensures emergency stops and hydraulic/pneumatic interlocks respond accurately

4. Full-Line No-Load Simulation & Pressure Test

• Continuous no-load trial and hydraulic pressure-retention test for at least 48 hours

• Monitors spindle bearing temperature, hydraulic oil stability, and VFD loop-sensing logic

5. Load Trial & Factory Acceptance Test (FAT)

• Real production trials with client-specified steel coils

• Measures spindle vibration, mandrel smoothness, and loop-sensing accuracy

• Documented with HD video and Quality Inspection Report for client approval

IV. Packaging & Shipping Methods

Packaging Standards:

1. Independent Wooden Crate Packaging

• Wear parts, electrical cabinets, toolkits, and manuals packed in fumigation-free crates

2. Dedicated Protection for Precision Components

• Rollers and high-precision parts individually wrapped to prevent scratches, deformation, or impacts

3. Comprehensive Weather & Impact Resistance

• Rust-preventative, waterproof, moisture-proof, and anti-collision treatments

4. Heavy-Duty Protective Wrapping for Container Loading

• Main machine structures wrapped in reinforced protective film for container transport

5. Modular Dismantling for Easy Unloading

• Oversized components disassembled into modules for crane lifting and hassle-free unloading

6. Secure Transit Tie-Down & Cargo Lashing

• Firm anchoring using steel wire ropes, turnbuckles, and heavy wooden chocks

• Prevents shifting or damage during ocean and land transport
