This part was formed with the HEATforming process.
The tubular blank was pre bended and heated by an
inductive heating up to 500-600°C. Thereafter the
tube was placed into a die, which determined the
shape of this part. The two dies have been closed
and the tube was sealed at both ends.
Due increasing air pressure up to 20 to 60 bar the
blank tube was formed into the die.
The cycle time for this part was about 20 seconds.
