Customized Rewinding Machines for Various Applications

Customized Rewinding Machines for Precision Steel Processing Across Industries Our advanced rewinding machines are engineered for high-efficiency post-processing of cold-rolled steel strips, delivering precision, reliability, and automation tailored to diverse industrial needs. These systems integrate core functions such as uncoiling, tension control, leveling, slitting, oiling, trimming, and re-coiling—ensuring each processed coil meets exact specifications for downstream applications. Designed with modular flexibility, our equipment supports customization across thicknesses, widths, and material types, making it ideal for manufacturers seeking scalable and adaptable production solutions. Key Features: - Fully digital automation using Siemens S7-1500 PLCs and SINAMIC drives (S120/G120 series) - Integrated Profinet and Ethernet-based communication for seamless machine-to-machine coordination - Advanced tension regulation and deviation correction for consistent strip quality - Robust mechanical design optimized for continuous operation in heavy-duty environments - Optional surface treatment modules including oiling, coating, or cleaning stations - Modular architecture enabling easy upgrades and integration into existing lines Detailed Description: The rewinding system begins with a high-performance decoiler that ensures smooth unwinding from raw coils while maintaining precise tension control—an essential step for minimizing edge damage and ensuring flatness. The strip then passes through a stretcher leveler, which corrects plate shape imperfections by applying controlled elongation under tension. This phase is critical for eliminating residual stresses and improving formability in subsequent processes like stamping or bending. Following leveling, optional features such as edge trimming, slit cutting, or surface lubrication enhance product consistency and performance. Finally, the re-winder forms a new coil with uniform tension, concentricity, and minimal defects—ideal for export-ready packaging or further processing. These machines support both standalone and inline configurations, allowing users to match capacity with production volume. The electrical control system, built around German-engineered components from Siemens, offers real-time monitoring, diagnostics, and predictive maintenance capabilities via integrated HMI interfaces. With a focus on energy efficiency, noise reduction, and ergonomic design, our solution aligns with modern manufacturing standards while reducing operational costs over time. Ideal Applications: - Cold-rolled steel mills producing sheet metal for automotive, appliance, and construction sectors - Coil-to-coil processing lines requiring high-speed, accurate re-winding - Metal fabrication facilities needing customized slitting and recoiling for specialized end products - OEM suppliers seeking automated, low-maintenance solutions for precision steel handling User Feedback: Customers worldwide report significant improvements in yield rates, reduced manual labor, and enhanced product uniformity after implementing our rewinding systems. One European auto parts manufacturer noted a 25% decrease in scrap rate within the first month of operation, attributing this success to the system’s intelligent tension management and real-time deviation correction. Another user in North America praised the intuitive interface and robust build quality, highlighting how the machine’s uptime exceeded 98% over six months of continuous use. Frequently Asked Questions: What materials can be processed by your rewinding machines? They are designed primarily for cold-rolled carbon steel, stainless steel, aluminum, and galvanized sheets, with customizable settings for different material properties and thicknesses. How does the tension control system ensure consistent results? A closed-loop feedback mechanism uses load cells and encoder signals to dynamically adjust motor torque, maintaining optimal tension throughout the entire process cycle regardless of coil diameter changes. Is remote monitoring available? Yes, the system supports Ethernet-based connectivity for remote diagnostics, parameter adjustments, and data logging, enhancing operational visibility without physical intervention. Can the machine handle variable coil sizes? Absolutely—the system includes automatic coil diameter detection and adaptive winding algorithms, enabling seamless transitions between different coil weights and dimensions without manual recalibration.
