SGCC Bending Process for customised drawing

Central to this process is the alignment of bending parameters with the unique requirements of the customised design. CNC press brakes equipped with precision tooling—such as V-dies and punches matched to the material thickness (typically 0.3mm to 3mm for SGCC)—are used to ensure consistent results. The tooling is selected based on the drawing’s specified bend angles (ranging from acute to obtuse) and internal radii, preventing excessive stress on the zinc coating that could lead to cracking or peeling, which would compromise corrosion resistance.​   Pre-bending preparation is critical, especially for complex customised shapes. This may involve laser cutting or shearing the SGCC sheet to the exact blank size specified in the drawing, ensuring clean edges that facilitate accurate bending. During bending, operators monitor parameters like bend force and speed, adjusting them to account for SGCC’s unique properties—its zinc layer adds slight ductility, requiring balanced pressure to avoi…
