Infinite variety of forms under high pressure
Hydroforming not only enables tube forming into complex three-dimensional shapes. Often it is possible to save further joining steps such as soldering or welding and to create a one-piece product with very good strength values via hydroforming. Hydroforming has established itself in many industries, from exhaust manifolds to solar plants, from design telephones to aerospace applications. The fischer group has integrated hydroforming into the group – first in Mexico – since 2001. Since 2007, with the acquisition of fischer Hydroforming, we have become one of the world's leading hydroforming companies and the technology leader in the field of hydroforming in Germany.
With 3,000 bar to revolutionary shapes
In hydroforming, hollow bodies are pressed from inside into a mold by means of high pressure of up to 3,000 bar. With this process, which is still innovative even after 30 years and whose limits have been approached but not yet reached, multistage mechanical forming steps can be efficiently combined.
Hydroforming has revolutionized the possibilities of tube forming with a new processing principle. A hitherto unknown variety of shapes became possible.
At the same time, choice with regard to design and materials is very free. Stainless steel, steel, aluminum or non-ferrous metals can all be used. These can be processed into exact dimensions and shapes – repeatability is also very pronounced in hydroforming. Hydroformed components thus offer the optimum combination of space efficiency, freedom of design and weight savings in combination with maximum strength and precision.
Process development in the age of Industry 4.0
Hydroforming is also progressing. Automation down to the ancillary processes, consistent lean production, implementation of Industry 4.0 principles for maintenance, production data collection and error prevention keep fischer specialists on their toes. New servo technology, energy efficiency, cycle time reduction and new control options also play their part.
