In the automotive manufacturing and auto parts industry, JINGSHI precision hydraulic and CNC leveling machines are widely utilized for the high-precision processing of body panels, structural components, brackets, stamped parts, and sheet metal prior to welding. By subjecting the sheet metal to repeated bending deformation through multi-roller leveling technology, these machines effectively eliminate internal stresses and significantly enhance flatness. This process effectively mitigates issues such as cracking and springback during stamping operations, thereby boosting product yield rates and providing a robust guarantee for the precision and reliability of automotive manufacturing.
