Heavy Gauge Coil Slitting
The Double Head Slitting Machine 12×1650MM is a heavy-duty steel coil processing line designed for high-efficiency slitting of thick steel coils. Equipped with two slitter heads, this advanced slitting system significantly reduces setup time and increases production efficiency, making it an ideal solution for steel service centers, coil processing companies, and steel manufacturers.
Designed to process heavy gauge materials up to 12mm thickness and 1650mm coil width, the machine provides excellent slitting accuracy, stable operation, and high productivity for demanding industrial applications.
Dual Slitter Head Design
The most important advantage of this machine is its double slitter head configuration. Operators can prepare one slitter head offline while the other head is running, allowing rapid changeover between production orders. This greatly reduces downtime and improves overall equipment utilization.
Heavy Gauge Processing Capability
The line is specially engineered for processing thick steel coils up to 12mm. Its robust mechanical structure and powerful drive system ensure stable performance even under heavy loads.
High Slitting Precision
Advanced tooling design and precision-guided strip handling systems ensure accurate strip widths, smooth edges, and excellent slit quality throughout the production process.
Automated Operation
Modern control systems provide automated operation, improving production consistency while reducing labor requirements. Operators can easily monitor and adjust production parameters through the control interface.
