Product Description
The High-Precision Silicon Steel Strip Slitting Line is a state-of-the-art coil processing solution engineered for transformer core manufacturing and electrical sheet metal industries. This automatic production line transforms large silicon electrical steel coils into precisely slit strips and re-coils them under controlled tension. Featuring a high-rigidity structure with a design deflection of 1/10,000 and Grade 4-5 precision tolerance, the system ensures minimal burr formation and exceptional edge straightness. Integrated with advanced Delta GJIM series PLC and touch screen HMI, the line offers seamless man-machine interaction, automatic speed synchronization, and robust reliability for continuous high-volume operations.
