Product Applications
Specialty Metals & Composite Materials Processing
Aerospace components, medical devices, and chemical container materials.
Titanium alloys, nickel-based alloys, and composite metal plates—highly complex machining is performed using blades made from special materials (such as cemented carbides and ceramic coatings) and heavy-duty leveling machines.
Precision Electronics AndElectrical Appliances
Transformer core, motor stator and rotor laminations, heat sinks, conductive connectors.
Silicon steel sheets, electrolytic copper strips, and alloy foils → Leveling machine (to relieve internal stress and ensure electromagnetic performance) → Slitting machine (for ultra-precise edge trimming with no burrs) → Flying shear (for fixed-length cutting)
New Energy Applications
Wind power: Thick steel plates—after being leveled—are used for the manufacture of tower sections and components.
Lithium batteries: Ultra-thin copper and aluminum foils are slit with extremely high precision by slitting machines—this is the core process. Leveling machines and flying shear machines may be used in the processing of casing materials. Photovoltaics: Aluminum frame profiles are rolled → leveled → slit → then sheared into flying shear mode to produce frame segments.
Automotive & Auto Parts Manufacturing
Body panels (doors, hoods), structural components (bumpers, chassis parts), seat frames, etc.
High-strength steel and aluminum alloy coils → Leveling machine (for precision leveling, critical for stamping) → Slitting machine (provides coil stock of specific widths for various parts such as door inner panels and longitudinal beams) → Flying shear (supplies fixed-length sheet metal for large-scale stamping lines).
Architecture & Building Materials Industry
Steel structural roofing/wall panels, curtain wall panels, and ceiling profiles.
Color-coated steel sheet, aluminum-magnesium-manganese coil, stainless steel coil → Leveling machine (corrects edge waviness) → Slitting machine (cuts into widths required for roof panels and wall panels) → Flying shear machine (cuts to fixed lengths for on-site installation)
Home Appliance Housing & Component Manufacturing
The outer shells and internal structural components of refrigerators, washing machines, air conditioners, and microwave ovens.
Cold-rolled steel sheet, galvanized sheet, and color-coated coil → Leveling machine (ensures a smooth and aesthetically pleasing surface) → Slitting machine (cuts into strips of varying widths for refrigerator door panels, side panels, and other components) → Flying shear (cuts the sheets into specified lengths) → Stamping/bending.
