Manufacturing method
Hydroforming is a fluid based manufacturing method. A tube is insert into a tooling cavity, filled with a fluid and is expanded with very high pressure into the tool.
1. Tube is inserted into the tool
2. Closing the tool
3. Approaching of the sealing cylinders & filling of forming medium
4. Generation of internal pressure feeding of sealing cylinders
5. Opening the tool & removing the part
The semi-finished product, mostly a straight or bent tube section, is inserted into a forming tool. The upper and lower die of the tool are then closed, the tube is filled with water and is sealed with the aid of axial cylinders.
By applying internal pressures of up to 4,000 bar, the tubes are precisely formed against the die geometry with absolute repetitive accuracy. The simultaneous feeding of the axial sealing cylinders supports the material flow and allows for the highest degrees of forming.
By using stress appropriate design and work hardening effects, a significant weight reduction can be achieved for the components.
Furthermore, the number of components and process steps can be reduced due to the complex shapes that are producible.
Small and Large-Scale Production
Automation
Depending on the annual volume the manufacturing process can be adjusted individually to obtain the cost optimum
Prototypes and small series are produced manually
Tailor-made automation of single processes complements the manual production in the event of medium-sized series
Large series are manufactured on fully-automated production lines
Your parts in expert hands: hydroforming, bending, laser cutting, heat treatment
Automated production for large series
