Hebei Xinnuo Press Machinery Co., Ltd specializes in the R&D and production of roll forming and metal processing equipment. Our automatic coil straightening leveling line, also known as simple flattening line, is designed to fix uneven, bent and wrinkled metal coils, widely used for color steel, galvanized sheet, cold rolled steel and aluminum coils in roofing, metal component manufacturing and hardware processing industries.
Many metal processors suffer from irregular raw plates caused by original coil curling, which leads to defective finished products and extra waste of raw materials. Our leveling line effectively solves this industry pain by flattening warped metal sheets into smooth flat boards in one continuous process, including uncoiling, feeding, multiple roller leveling and fixed-length cutting as needed.
This simple leveling production line adopts solid heavy steel frame and high-hardness leveling rollers processed by fine grinding. Compact overall layout saves workshop space and brings convenient daily maintenance. Equipped with standard electric control system or optional PLC automatic control, operators can easily adjust feeding speed and leveling clearance without complicated professional training. The machine runs smoothly with low vibration and low failure rate for long-time continuous shift production.
All technical parameters can be customized according to clients’ raw material thickness, original coil width and daily output demands. Strict factory inspection is carried out before shipment to guarantee stable working condition. Xinnuo provides professional installation guidance, operation training and long-term after-sales service for overseas customers from Southeast Asia, Middle East, Africa and Europe.
Select our reliable straightening leveling line to upgrade your pre-processing workflow, reduce scrap loss and improve finished product qualification rate for long-term profit growth.
