Tubular Hydroforming is the Way Forward

Tubular Hydroforming is the Way Forward

Tube hydro-forming is a concept in the metal fabrication industry that has been well-known for more than three decades. However, in the past years this method has only been effective in the production of a limited amount of products. Today, tubular hydroforming allows for mass production and a wide range of shapes.

The automotive industry is one of those that have taken advantage of this technological advancement to replace the ancient stamping method. The internal hydraulic pressure that this technology utilizes makes it possible for metals to bend slightly or be straightened effortlessly. Components such as space frames, engine cradles and other parts can be produced in plenty.

One of the features that give tubular hydroforming a competitive edge in the automotive market is the ability for light-weight equipment to be produced. The recent hydro-formed components utilize steel and aluminum, which are featured as the lightest and durable metals. With this advancement, manufactures can also be able to customize wall thickness of the outputs.

According to The Fabricator, “Tube hydroforming allows engineers to optimize their designs through cross sectional reshaping and perimeter expansion.” This means that scrap metal is reduced because one can set the system to cut the exact size of pieces they need. In turn, it reduces the cost of production for firms.

The components produced using these methods are of high quality. There is a tolerance for tight dimensions and spring backs. These characteristics are achieved through the extensive elongation of the metal beyond its yield point. Prevention of spring backs and tight tolerance translate to mean that pieces are strongly joined, and this leads to increased structural strength and stiffness of the products. To the consumer, this is vital as it guarantees a longer life of the vehicles they purchase.

To address matters of friction within the hydro-forming equipment, one needs to select the right lubricant. The parameters that one should contemplate about include the distance involved in the part to be produced, the internal pressure and the sliding velocity of the machine. Commonly applied lubricants are oils, waxes and any other lubricant that is free of polluting elements such as debris.

The application of the tubular hydro-forming technology is evident in the BMW5, which has a hyrdo-formed aluminum rear axle. This is a production technique that will see many firms achieve their production volume goals.
