The 1350mm slitting line, manufactured in 2016 by Foshan Hongjia, is a high-performance processing solution engineered for demanding, high-volume production environments. This line specializes in the high-speed slitting of thin to medium-gauge materials, with a precise thickness range from 0.2mm to 3.0mm, making it exceptionally versatile for a wide array of industrial applications.
Built for continuous operation, it incorporates advanced technological features such as a seamless rewinding system and centrifugal scrap edge winding. These innovations are designed to maximize uptime, improve material yield, and maintain consistent, high-quality output over extended production runs. With a proven operational history since 2016, this slitting line offers the reliability of a seasoned asset, having been tested and validated in real-world, demanding industrial applications, thereby minimizing operational risks for new owners.
| System Component | Technical Specification | Technical Elaboration & Operational Impact |
|---|---|---|
| Main Drive System | 75kW High-Efficiency Motor | This motor provides the primary power for pulling material through the line. Its high-efficiency design ensures stable speed control and smooth acceleration, which is crucial for processing delicate thin-gauge materials without causing stretching, tearing, or surface marring. It forms the foundation for consistent line speed and process stability. |
| Rewinding System | 90kW Powerful Rewinding Motor | The 90kW rewinding motor is strategically more powerful than the main drive, creating a "pull-dominated" tension system. This configuration is essential for applying high, controlled tension during the rewinding of large-diameter coils, ensuring they are wound tightly and uniformly. This prevents common issues like coil collapse (telescoping) or loose layers, which are critical for downstream automated handling. |
| Tooling System | 200mm Diameter Heavy-Duty Shaft | The 200mm shaft provides the massive rigidity required for high-speed slitting. Its significant diameter guarantees minimal deflection under load, which is paramount for maintaining ultra-tight width tolerances across the entire 1350mm working width and for producing clean, burr-free edges, even at maximum operational speeds. |
| Material Range | 0.2-3.0mm Thickness | This specific range highlights the line's specialization. It is finely tuned to handle the challenges of thin-gauge processing (preventing wrinkling and breakage in 0.2mm material) while retaining the structural integrity to efficiently process material up to 3.0mm thick, offering exceptional application versatility. |
| Special Features | Seamless Rewinding, Centrifugal Scrap Winder | Seamless Rewinding: Allows for the automatic transfer of the strip from a full coil to a new mandrel without stopping the line, eliminating the productivity loss and potential head/tail scrap associated with manual coil changes. Centrifugal Scrap Winder: A fully automated system that continuously draws in slit edge trim, winds it into a compact bundle, and ejects it, maintaining a clean and safe work environment and eliminating manual scrap handling. |
1. Superior Thin-Gauge Processing Expertise
This line is not just capable of processing thin materials; it is engineered for it. The precise tension control afforded by the balanced motor configuration, combined with a stable tooling system, prevents common thin-gauge defects such as edge wave, camber, and breakage. This ensures a consistently high yield and superior quality when processing materials for sensitive applications like appliance interiors or automotive components.
2. Maximized Uptime with Advanced Rewinding Technology
The seamless rewinding (or "loop pit"/"duplex rewind") system is a critical feature for high-volume operations. By enabling continuous operation during coil changes, it significantly increases the line's overall equipment effectiveness (OEE). This non-stop capability is essential for meeting tight production deadlines and is particularly valuable when processing premium, coated materials where any stop-start mark could render the material non-conforming.
3. Automated, Hands-Free Scrap Management
The centrifugal scrap winder revolutionizes waste handling. It automates a traditionally labor-intensive and potentially hazardous process, allowing the line to run for extended periods without intervention for scrap removal. This not only boosts productivity but also contributes to a cleaner, safer, and more organized factory floor, aligning with modern 5S and lean manufacturing principles.
4. Optimized Power for Speed and Stability
The 75kW/90kW motor pairing is calibrated for high-speed performance without sacrificing control. The main drive provides smooth, consistent pull, while the more powerful rewinder maintains dominant tension. This balance is crucial for preventing speed-related flutter in thin materials and for ensuring that finished coils are of the highest integrity, ready for shipment or further processing.
High-Volume Processing Core Asset: An ideal primary line for metal service centers and manufacturing facilities that specialize in large-volume orders of thin to medium-gauge materials, requiring a machine built for endurance and speed.
Serves Quality-Critical Industries: Excellently suited for supplying the automotive, appliance, and construction sectors where consistent slit width, edge quality, and coil integrity are non-negotiable for automated production lines.
Enables Premium Material Processing: The seamless rewinding feature makes this line exceptionally capable of handling painted, laminated, or other surface-sensitive materials where any scratch or stop-mark would result in significant value loss.
Reduces Total Cost of Ownership: As a proven 2016 model, this asset offers modern performance without the depreciation of new equipment. Its advanced features directly reduce labor costs and material waste, while its proven reliability minimizes unplanned maintenance and production losses.
The 1350mm slitting line represents a strategic opportunity to acquire a high-caliber, production-proven asset. It delivers an unparalleled combination of speed, precision, and automation for thin to medium-gauge material processing. Its advanced seamless rewinding and centrifugal scrap management systems are engineered to maximize productive uptime and operational efficiency. For metal processors seeking to enhance their capacity with a reliable, high-output solution that minimizes waste and labor input, this line offers a compelling value proposition, blending proven performance with the productivity features demanded by today's competitive markets.
