This is a thick iron stamped panel with a blue zinc finish for excellent durability and corrosion resistance. In the stamping process for thick iron materials, punching and bending are two crucial steps. Punching is one of the most common stamping processes. It's mainly used to cut the iron sheet into the desired shape and size. During punching, the die and punch apply high pressure to cut or separate the material. After punching, the edges often have burrs, especially with thick iron. The material's thickness creates more friction, which makes burrs more pronounced. These burrs can affect the fit and appearance of the parts, so they usually need to be removed in post-processing. Bending involves bending the iron sheet at a specified angle to create parts with angled or complex shapes. Bending thick iron is more challenging. It requires precise control of the pressure and bending angle to prevent the material from breaking or deforming unevenly.
