What is ironing sheet metal?

Ironing is a metal forming process used to reduce the thickness of sheet metal. It utilizes a series of dies to press and shape the metal into the desired shape and thickness. The process can be both cold and hot but is typically done at room temperature.

Ironing is commonly used in the production of cans and other thin-walled containers. It can also be used to create non-cylindrical shapes such as rectangular or square containers. The process results in a smooth and uniform surface finish with minimal deformation, making it ideal for high-volume production runs.

One of the major advantages of the ironing process is that it can be used to achieve extremely tight tolerances. It is also a very efficient process, as it reduces material waste and can be performed rapidly on automated production lines. However, the process does require specialized equipment and expertise, which can increase the initial investment costs.

Overall, ironing is a highly effective metal forming technique that can produce high-quality, consistent products at scale. It is a valuable method for achieving thin gauges and tight tolerances in sheet metal production.
