Product  Details and Advantages Of Resilient Cut To Length Line:

Cut-to-length lines are essential for sheet metal production, transforming a mother coil into precisely cut, flat sheets by leveling and cutting it into individual cross-sections. These systems ensure that the resulting sheets are perfectly flat and neatly stacked for further use or shipment.

 

The innovative technology used in ZTRFM’s leveling lines ensures both high production speeds and superior flatness. In addition to the core equipment, ZTRFM also offers a range of optional features that can be integrated into the cut-to-length lines to enhance performance, including:

 

– Edge Trimmers and Scrap Choppers for precise material edge handling

– Precision Levelers for achieving perfect flatness

– Automatic Leveler Cassette Change for efficient roll management

– Stretch Levelers for specialized material treatment

– Presetting Systems for leveler adjustments, shear gap control, and stacker configuration

– Various Shear Options such as rotary, flying, and electronic shears

– High Production Cyclic Rolls and shear systems for efficient processing

– Stacking Solutions including bomb-door, combined, and magnetic stackers

– Packing and Strapping Systems to ensure secure packaging of the finished products

The core operation of cut-to-length lines involves several steps: unwinding the coil, leveling the material, cross-cutting it to the desired length, stacking the cut sheets, and finally packaging them for delivery.

ZTRFM offers a variety of shearing technologies, including rotary, flying, and stop/start shears, as well as multiple stacking solutions such as bomb-door, air-blow, combined drop-airblow, and sliding systems. Their state-of-the-art roller leveler and stretch leveling technologies are designed to deliver optimal results in both precision and performance.

ZTRFM has made significant advances in the development and refinement of each process in the cut-to-length line, with a focus on three key factors for ensuring high-quality final products:

1. Precision Leveling:ZTRFM provides several options for high-quality leveling, including both 4-high and 6-high precision levelers with robust, high-precision leveling rolls. These systems are designed to handle a range of materials with exceptional accuracy
2. Efficient Production:With a diverse selection of shears—ranging from start-stop to flying and rotary—along with various stacking solutions like sliding, turbo-blower, bomb-door, combined, magnetic, and vacuum stackers, ZTRFM guarantees optimized production efficiency and smooth material handling.
3. Surface Protection: Special attention is given to preserving the surface quality of sensitive materials such as stainless steel and aluminum during the leveling and cutting process.
