Internal and external high pressure forming
By means of internal and external high-pressure forming (IHU, AHU), complex-shaped hollow bodies or molded parts can be produced.
For this technology, DUNKES manufactures internal and external high-pressure forming lines in the range between 1,000kN and 40,000kN as frames or 3/ 4-column presses individually according to customer requirements.
Starting with prototyping up to the realization of series production, the required press technology, if necessary tool technology, high pressure technology as well as the required number of additional axes can be supplied. Software specially developed for hydroforming guarantees an optimum basis for creating the extensive sequence programs. Instead of a compact control system with a very limited range of applications, which would have to be adapted separately to each customer, there is a modular system that can be optimally adapted to the respective requirement by changing individual components. Thus, a high degree of modularity and reusability and thus a high quality standard is achieved.
Internal high pressure forming
In internal high-pressure forming, the forming of a tube, for example, is carried out via internal pressurization.
We offer a variety of options for hydroforming equipment, including:
- Complete HFA* fluid systems
-
Pressure intensifier up to 3,000 bar
- Multi-axis feed cylinder axes
- Additional hydraulic functions
- Quick-change systems
-
Data acquisition packages
-
Remote diagnostic packages
*) HFA is an oil-in-water emulsion with a water content > 80%. In most cases, a water content of > 95% is used. The advantage of low cost (mineral oil content) and low compressibility are offset by the disadvantages of low viscosity (leakage losses) and low lubricity. To avoid excessive water loss by evaporation, the HFA temperature must not exceed max. 60° C.
