The 450mm Slitting Line, precision-engineered in Wuxi, is a specialized processing solution designed for manufacturers where accuracy, space efficiency, and immediate operational readiness are critical. This system is meticulously crafted for high-accuracy slitting of a diverse range of materials, including cold-rolled steel, galvanized steel, and stainless steel.
Its compact 450mm footprint is a key feature, allowing it to be deployed in limited-space workshops or integrated seamlessly into existing production cells without compromising on industrial-grade performance. The line arrives as a complete package, including an extensive inventory of blades and a full set of spacers. This turn-key approach eliminates procurement delays, ensuring immediate operational readiness from the moment of installation and making it the perfect asset for specialized metal processing that demands tight tolerances and unwavering consistency.
| System Component | Technical Specification | Technical Elaboration & Operational Impact |
|---|---|---|
| Main Drive System | DC 22kW Precision Motor | This motor provides the primary drive for the slitting process. The DC technology offers exceptionally smooth and responsive speed control, which is paramount for maintaining a consistent feed rate. This stability is the foundation for achieving uniform strip quality and precise length control, especially critical when processing thin or delicate materials. |
| Rewinding System | DC 55kW High-Torque Motor | The strategic use of a significantly more powerful DC motor for rewinding ensures superior tension control. The high-torque characteristic provides the force necessary to maintain precise, constant tension throughout the coiling process. This results in tightly wound, perfectly aligned finished coils that are essential for high-speed automated feeding in subsequent manufacturing steps like stamping or roll-forming. |
| Tooling System | 80mm Diameter Precision Shaft | While compact, the 80mm shaft is engineered for precision. Its design prioritizes rigidity and minimal runout, ensuring exceptional rotational stability during high-speed operation. This directly translates to superior slit edge quality, exact width tolerances, and virtually burr-free edges, which are non-negotiable for precision components in electronics and automotive applications. |
| Tooling Inventory | Extensive Blades & Complete Spacer Sets | This is a significant operational advantage. The comprehensive kit includes a wide array of slitting knives (likely covering different hardnesses and geometries for various materials) and a complete matrix of spacers. This empowers manufacturers to respond instantly to changing production orders with different width requirements, drastically reducing changeover time and eliminating the capital outlay for initial tooling. |
1. Optimized Power & Tension Management for Flawless Results
The deliberate imbalance between the 22kW main motor and the 55kW rewinding motor is a mark of advanced slitting line design. The main motor ensures a smooth, steady feed, while the powerful rewinding motor dominates the tensioning process. This creates a "pull-dominant" system that keeps the strip perfectly taut and stable through the cutting head, preventing tension-related defects like edge wave, camber, or broken strips, thereby guaranteeing a flawless finish on every slit.
2. High-Accuracy Tooling for Micron-Level Precision
The 80mm precision tool holder shaft is the heart of this machine's accuracy. Engineered for high rotational stability rather than brute force, it minimizes dynamic vibration at high operational speeds. This ensures that each slit strip maintains consistent width with micron-level tolerances and produces a clean, square edge. This level of precision is essential for components where the edge is a functional surface or for applications requiring perfect fit and finish.
3. Unmatched Production Agility and Flexibility
The extensive blade and spacer inventory transforms this slitting line from a fixed-purpose machine into a highly flexible production asset. Manufacturers can switch from processing hard stainless steel to soft galvanized steel, or change slit widths, with minimal downtime. This agility allows for efficient, small-batch production runs, making the operation highly responsive to custom orders and just-in-time manufacturing schedules.
4. Space-Efficient Design without Performance Compromise
The 450mm width is a strategic design choice for maximum space utilization. It allows companies to install a full-capability slitting operation in areas where a standard-sized line would be impossible, such as in R&D labs, pilot production lines, or crowded job shops. This compact footprint enables businesses to bring high-value slitting operations in-house without the need for costly facility expansions.
Empowers Precision Manufacturing: An ideal core asset for manufacturers of precision components, electronic parts (such as connector shields and enclosures), and specialized fabricators where material edge quality and dimensional accuracy directly impact product performance.
Serves High-Value Industries: Perfectly suited for supplying the automotive trim, consumer electronics, telecommunications, and specialized mechanical components sectors, where consistent, high-quality narrow-width material is required.
Enhances Operational Economics: The comprehensive tooling package significantly reduces both initial investment and long-term operational costs by deferring tooling purchases and minimizing machine downtime during product changeovers.
Facilitates Lean Manufacturing Integration: The compact design and quick-change capabilities make it an excellent fit for lean manufacturing environments, allowing for seamless integration into value streams and supporting a pull-based production system.
The 450mm slitting line delivers a powerful synergy of precision engineering, operational agility, and space efficiency. It is the definitive solution for specialized manufacturers for whom uncompromising slit quality and rapid response to production demands are key competitive advantages. By combining a precision DC motor system for flawless tension control with an extensive, inclusive tooling package, this line offers immediate production capability and long-term operational flexibility. It represents a strategic investment that not only saves valuable floor space but also enhances a company's capability to produce high-value, precision-focused products with exceptional efficiency and reliability.
