MFL2 Uncoiler Straightener Feeder (0.3–3.2mm)

SUNRUI MFL2 3-in-1 uncoiler straightener feeder integrates three essential functions — unwinding, leveling, and precision feeding — into a single, space-saving unit. The uncoiler holds and unwinds the metal coil, the straightener removes curvature and internal stress through a series of leveling rollers, and the servo feeder delivers the leveled strip into the press with consistent accuracy, ensuring smooth and efficient stamping operations.

This versatile system handles a wide range of materials, including stainless steel, carbon steel, aluminum, and copper. It is widely used in the production of metal parts for automotive components, electronic hardware, household appliances, and general metal stamping applications. 

The MFL2 features a compact footprint that integrates seamlessly into existing production lines. Equipped with a servo-driven feeder, PLC touchscreen control, and precision sensors, it ensures accurate material positioning with ±0.15mm feed accuracy. The user-friendly interface simplifies setup and operation, reducing changeover time and minimizing material waste.  

Overall, the SUNRUI MFL2 uncoiler straightener feeder is a reliable, efficient, and cost-effective solution for metal coil processing — delivering consistent quality, reduced downtime, and higher productivity for your stamping line.

● AUTOMOTIVE

● ILLUMINATION

Many solutions for the blanking of metal parts for lighting sector. Several parts such as housings, panels, brackets, feet, arms, buttons, diffusers, etc ...

● Space-Saving & Easy Integration

The MFL2's compact 3-in-1 design eliminates long material loops, significantly reducing the workshop footprint compared to traditional separate-unit lines. Its integrated structure simplifies installation, allowing for faster production ramp-up. The automated lubrication system and self-diagnostics further minimize maintenance and downtime.

● Modular & Smart Control

Control is fully centralized through a PLC system. All parameters for the decoiler hydraulic station, coil car, drive motor, and servo feeder are managed via a 7-inch high-precision HMI touchscreen. Operators can easily set and save stamping process parameters, reducing setup time and manual errors.

● High-Precision Straightening & Feeding

Unlike separate units that can suffer from synchronization errors, the MFL2 integrates decoiling, straightening, and feeding. Driven by a high-precision servo motor and PLC system, it ensures consistent feeding accuracy of ±0.1mm, critical for progressive die stamping. The straightening rollers (GCr15, HRC58-60°) are hard-chrome plated and precision-ground for durability.

● Reliable Structure & Long Lifespan

The main body is treated with shot blasting to enhance paint adhesion and surface hardness, followed by high-end vehicle-grade painting for superior corrosion resistance in harsh environments. All key components are machined with advanced CNC equipment and precision testing instruments from Germany, Japan, and Taiwan to guarantee long-term stability and accuracy.
