HEATforming provides a competitive alternative to Hydroforming or Superplastic Forming (SPF) of tubes, and even die casting and forging in some cases.
Hot metal gas forming (HMGF) - compare "HMGF" at wikipedia.org - , gasforming, warm forming or hot forming is often used to describe this metal forming process and is suitable for almost all tube blanks - extruded, drawn or seam welded.
Compared to Hydroforming, HEATforming provides higher forming ratios in less cycle time and in one process step. The HEATforming Equipment is much smaller, movable and can be easiliy integrated in a production line.
This 23 second animation shows the HEATforming process in real time.
The final geometry is formed with an increase of inner pressure.
