Description

Technical Field

In addition, folding also helps to achieve the beauty of the shape and prevent the separation of the opening part. Galvanized sheet refers to a steel sheet with a layer of zinc on the surface. Galvanizing is a frequently used economical and effective rust prevention method, and about half of the world's zinc production is used for this process. In order to ensure the strength of the galvanized sheet during processing, it is necessary to perform folding stamping on its edges. The existing folding stamping equipment needs to adjust the position of the galvanized sheet multiple times during use, and the folding stamping process can only be completed after multiple treatments.
