What is hydroforming?
Hydroforming is a forming process that uses water or other fluid pressure to form materials into a desired shape. In the classic sense, hydroforming mainly refers to internal high-pressure forming, in which pressure is applied to a material from the inside in order to press it into a shape.
FF Fluid Forming GmbH uses an advanced, patented process that differs from classic hydroforming. With the FormBalancer hydroforming machine, not only internal high-pressure forming, but also external high-pressure forming is possible. This means that pressure can be applied to the material from both the inside and outside to create complex sheet metal shapes.
How does hydroforming work with the FormBalancer?
Hydroforming with the FormBalancer is a high-pressure forming process in which metal blanks are formed into a desired geometry under high pressure with the help of a fluid. Hydroforming is similar to conventional deep drawing with a counter mold. The special difference to conventional technology is that instead of a stamp, forming is carried out with an active medium. Medium pressures of up to 4000 bar are required for this forming process, which means, depending on the component size, that very high mold closing forces have to be applied.
The desire of many component designers and designers to implement this technology has so far failed because of suitable forming machines with which this specialized hydroforming technology could be implemented. The FormBalancer opens up a wide range of applications in various sectors such as automotive, aerospace, medical technology and many others where complex components have to be manufactured with high precision and quality.
What advantages does hydroforming offer over deep drawing?
Hydroforming is similar to conventional deep-drawing, but has significant advantages in terms of the molded part and tool costs or component manufacturing costs. The FormBalancer creates many attractive possibilities with cost-effective implementation processes. We can produce special products for every industry. See for yourself.
