This high-performance 850mm slitting line, manufactured in 2019 by Hengda Changtian, represents a prime example of modern metal processing technology. It was engineered for precision, reliability, and versatility in medium to high-volume production environments. The line is specifically designed to handle a diverse range of materials—from standard cold-rolled and galvanized steels to the more demanding stainless steels—while maintaining consistent, high-quality output.
A significant advantage of this particular system is its immediate operational readiness. It comes complete with a full set of blades and spacers, effectively making it a "turnkey" solution that minimizes setup time and additional investment. Having been maintained since its 2019 manufacture, it offers the perfect blend of contemporary engineering and proven, reliable performance without the premium cost of brand-new equipment.
| System Component | Technical Specification | Technical Elaboration & Operational Impact |
|---|---|---|
| Main Drive System | 90kW High-Efficiency Main Motor | This robust motor provides the primary power for the slitting process. Its high-efficiency design ensures stable speed and torque, crucial for maintaining consistent feed into the cutting head. This stability is the foundation for achieving uniform strip quality and preventing speed-related defects, especially during acceleration and deceleration. |
| Rewinding System | 110kW Powerful Rewinding Motor | The rewinding motor is more powerful than the main drive, a configuration designed for superior tension control. This 110kW unit provides the necessary torque to handle full-sized coils and maintain precise, high tension throughout the winding process. This results in tightly wound, properly aligned finished coils that are essential for automated downstream processes. |
| Tooling System | 200mm Diameter Heavy-Duty Tool Holder Shaft | The 200mm shaft is a hallmark of a heavy-duty slitting line. Its significant diameter provides exceptional rigidity, dramatically minimizing flex and vibration during slitting. This directly translates to superior slit edge quality, exceptional width tolerances across the entire coil, and significantly reduced burr formation, even when processing high-strength materials. |
| Year of Manufacture | 2019 | As a 2019 model, this equipment benefits from modern design standards, electrical efficiency, and control system capabilities. It is not yet subject to the high maintenance cycles of older machinery, offering a refreshed asset with a substantial remaining service life. |
| Spare Parts & Tooling | Complete set of blades and spacers included | This is a critical value-add. The inclusion of a comprehensive blade and spacer kit eliminates the lead time and capital outlay for these essential, high-cost consumables. It allows for immediate production across various widths and materials and provides a vital inventory for future changeovers, maximizing uptime. |
1. Optimized Power Distribution for Enhanced Process Stability
The strategic configuration of the 90kW main motor and 110kW rewinding motor creates a perfectly balanced power profile. The main motor ensures smooth, consistent material feed, while the more powerful rewinding motor dominates the tensioning process. This balance prevents issues like tension-induced strip breakage or loose winding, ensuring flawless processing across a wide spectrum of material types and thicknesses, from thin-gauge galvanized steel to full-hard stainless.
2. Precision Engineered for Superior Slit Quality
The heart of this line's precision is the 200mm heavy-duty tool holder shaft. Its massive construction guarantees unparalleled stability, effectively eliminating deflection under the extreme lateral forces of slitting. This robust foundation, combined with precision-ground blades, ensures that every slit strip meets exact width specifications with clean, vertical, and burr-free edges, ready for critical applications in automotive or appliance manufacturing.
3. Immediate Operational Readiness & Reduced Downtime
The inclusion of a complete blade and spacer set is a significant operational advantage. It transforms the commissioning process, allowing production to commence immediately after installation. Furthermore, it drastically reduces changeover time between different slitting jobs, as the necessary tooling is on hand. This directly increases overall equipment effectiveness (OEE) by maximizing productive runtime.
4. Proven Reliability with Modern Efficiency
As a 2019 model from a recognized manufacturer like Hengda Changtian, this slitting line offers a lower-risk investment compared to older, fully depreciated equipment. It incorporates contemporary electrical standards and mechanical designs, leading to higher energy efficiency, more readily available spare parts, and lower ongoing maintenance requirements. It provides the performance of a modern machine without the associated capital expenditure of a new purchase.
Versatile Core Asset for Metal Processors: An ideal primary or secondary line for metal service centers and manufacturing plants that need to efficiently process mixed material portfolios without sacrificing quality.
Serves Demanding Industrial Sectors: Excellently suited for supplying slit coil to the automotive component, construction material, and domestic appliance industries, where consistent material quality is non-negotiable.
Lowers Total Cost of Ownership: The modern manufacture reduces the risk of frequent breakdowns, while the included tooling package defers a significant capital expense. This combination leads to a lower total cost of ownership and a faster return on investment.
Enhances Production Agility: The ability to quickly change over and process different materials makes the entire production facility more agile and responsive to customer demands and changing market orders.
This 2019 850mm slitting line from Hengda Changtian represents a strategically astute capital equipment investment. It delivers an optimal synergy of modern engineering, proven field reliability, and immediate production capability. The robust power configuration ensures consistent, high-quality slitting across diverse materials, while the comprehensive inclusion of blades and spacers makes it operationally ready from day one. For manufacturers seeking to enhance or expand their processing capacity with a reliable, high-performance, and cost-effective solution, this slitting line offers exceptional value, combining the benefits of contemporary technology with the practical advantages of a well-maintained, pre-owned asset.
