High-Quality The Levelers Manufacturers & Factory

We manufacture complete coil processing lines: high-precision levelers, heavy plate straightening machines, slitting lines (rotary shear lines), cut to length lines, high-speed flying shear production lines, and continuous galvanizing lines. Machinery can be delivered as complete integrated turnkey processing plants or supplied as modular stand-alone levelers to retrofit and upgrade existing customer lines.

Our lines are engineered to process hot-rolled coils, cold-rolled carbon steel, galvanized coil, electro-galvanized strip, silicon electrical steel, stainless steel grades (such as AISI 200, 300, and 400 series), titanium, and aluminum alloys (from soft 1xxx series to aerospace 6xxx/7xxx series). Each unit is customized according to yield strength ($R_p0.2$), coil gauge, strip width, and surface-finish sensitivity.

Select a Slitting Line when the ultimate downstream requirement is narrow mult-coils for feeding tube mills, roll formers, or progressive stamping dies. Choose a Cut to Length Line with a start-stop shear when producing high-accuracy flat rectangular sheets stacked on pallets for general fabrication. Select a Flying Shear Production Line when high linear output and surface protection are paramount, because the shear synchronizes speed with the continuously moving strip, eliminating stop-start roller marks and quadrupling sheet output per hour. Combined slitting and cut-to-length solutions are also engineered for facilities with footprint restrictions.

A standard flattener typically utilizes 5 to 9 large-diameter rollers without intermediate backup support; it only corrects macro coil set and gross lengthwise curvature. A Precision Leveler utilizes 13 to 23 smaller-diameter rollers supported by multiple banks of adjustable backup rollers. This multi-roll architecture allows targeted transverse deflection, enabling operators to bend specific zones of the strip (such as edges or center) to achieve uniform internal fiber length, eradicate edge waves, eliminate center buckles, and release internal residual stress down to negligible levels.

To provide a fully calculated engineering layout and quotation, our engineers require: material grade and yield strength limit ($N/mm^2$), strip thickness range (min/max), coil width range, maximum coil weight, inner/outer coil diameters, required finished sheet lengths or slit strip widths, target linear operating speed ($m/min$), flatness tolerances (e.g., standard DIN EN 10051 or precision ≤3 I-units), and plant electric voltage supply (e.g., 380V/480V 50/60Hz).

Yes. Our dedicated field-service engineering team routinely deploys overseas to supervise foundation installation, mechanical leveling, electrical cabling integration, hydraulic circuit flushing, and trial coil running. Furthermore, we run complete operational and PLC training programs for your technicians, supported indefinitely by remote VPN diagnostics and factory-direct replacement parts dispatch.

Yes, we welcome international buyers and third-party inspection agencies (SGS, TUV, Bureau Veritas) to inspect machinery prior to shipment. Our 40,000 m² heavy production base is situated in Wuxi, Jiangsu Province, easily accessible within 45 minutes from Shanghai via high-speed railway. We conduct comprehensive dry-run cycles and full-load validation tests directly in front of the purchasing committee.
