Hydroforming is defined as the process in which metal is shaped using fluid dynamics. The result is lightweight, structurally strong, stiff pieces of the original metal. Metals that can be hydroformed include, but are not limited to brass, stainless steel, low-alloy steel, and aluminum.
Hydroforming became popular in the early 1900s as the automotive industry began to take hold in the United States. The process allowed automotive manufacturers a more desirable alternative to casting using die sets. Die-set part manufacturing required more finishing work and produced less structurally sound parts due to metal stretch and excessive handling.
Hydroforming tools were born as a result of the arduous research and development of the Cincinnati Milling Machine Company founded by Geiger and Holtz in 1889. By the 1930s, the Cincinnati Milling Company was the main supplier of metal forming machines in the U.S. and Europe. As the demand for shaped metal parts increased, the Cincinnati Milling Machine Company began the process of developing deep draw forming techniques using lighting reflectors and gear case covers.
The company was transformed in 1956 to Cincinnati Milacron and research and development of the hydroforming process accelerated. This allowed more advanced forms of hydroforming to begin to take shape. As a result, the old style of deep draw became obsolete and more modern hydroforming techniques began to take the helm. By the 1970s, Hydroforming was officially out of its fledgling stages. These hydroforming machines reduced the need for excessive metal part finishing, which in turn reduced the turn over time for parts, increased efficiency, and reduced the workforce needed to produce quality product.
American Hydroformers has effectively mastered the tubular hydroforming process, supplying multiple industries with high quality hydroformed parts. For over ten years we have continued to raised the bar, producing the most durable, uniquely crafted, and versatile hydroformed parts on the market.
