3. Versatility Modern pipe punching machines are designed to handle a variety of pipe sizes and materials, including steel, aluminum, and plastic. This versatility enables manufacturers to use a single piece of equipment for multiple projects, significantly reducing the need for specialized machines.
4. Annealing Following the cold rolling process, the steel strips may require annealing. This heat treatment process relieves internal stresses that develop during cold rolling, restoring ductility and reducing hardness. The annealing process can be performed in a continuous furnace where the steel strip is heated and then gradually cooled.
