Automatic Hydraulic New Straightening Machine Metal Sheet Steel Plate Straightener Sheet Metal Flattening Machine

Product Description

Heavy Duty Flattening Machine for Thick Metal Plate Straightening

Product Description

This is the JINGSHI Sheet Metal Leveling Machine, an industrial-grade metal sheet processing equipment: Equipped with an automatic conveying roller table, it eliminates warpage and deformation of materials (such as steel plates, aluminum plates) through the extrusion and stretching of internal multiple sets of leveling rollers, restoring the sheets to a flat state. The machine integrates an operation display screen and safety control components, supporting continuous leveling of large-format materials, and is commonly used in sheet metal preprocessing procedures in industries like hardware and automotive manufacturing.

Product Applications

1.Sheet Metal Processing Industry
Widely used for leveling various metal sheets like stainless steel, cold-rolled steel and aluminum plates in sheet metal processing. It ensures the flatness of blanks and finished parts, laying a solid foundation for subsequent cutting, bending and welding processes with high precision requirements. 
2.Automobile Manufacturing Industry 
Applied to leveling metal panels for automobile body parts such as car hoods, door panels and chassis components. It can eliminate the internal stress and warpage of metal sheets after stamping, ensuring the fitting accuracy and assembly quality of automobile structural parts. 
3.Hardware & Precision Parts Industry
Suitable for leveling thin and small metal sheets used in hardware accessories, electronic precision parts and instrument components. It strictly controls the flatness error of small workpieces, meeting the dimensional accuracy requirements of micro-part processing and assembly. 
4.Building Materials & Decoration Industry
Used for leveling aluminum alloy panels, galvanized sheets and color steel plates applied in building exterior wall decoration, ceiling and partition production. It ensures the flat and smooth surface of decorative metal plates, avoiding uneven installation and improving the overall building decoration effect.  
5.Home Appliance Production Industry
Applied to leveling metal shell sheets of household appliances such as refrigerators, washing machines, air conditioners and microwave ovens. It removes the deformation of metal sheets during rolling and transportation, ensuring the smooth forming and beautiful appearance of appliance shells.

Product Advantages

1.Precision leveling can repeatedly bend sheet metals byuse of many overlapped leveling rollers. The intermesh isadjustable, which can help implement the bendingprogram required by leveling and wil notdamage theappearance of sheet metals.

2.The lengths of metal fibers are becoming more and moreconsistent and the inner stress of material isremoved atthe same time after the sheet metals are bent repeatedly.in such a case the sheet metals arenaturally leveled.

3.Many users choose precision leveling technology insteadof cutting to pursue flatness, which can effectively savematerial loss.

4.Precision Leveling can reduce human cost and help getrid of the technical dependence on traditionallevelingexperience because the use of continuous and repeatedbending technology multiplies levelingefficiency anduses it in the production line.
