Super - Plastic Forming - Process

This method consists in hot forming up to 1000° Celsius superplastic alloys by using an inert gas pressured up to 50 bars. Combined with diffusion bonding, this process allows honeycomb structures made of several sheets in a single operation.

Loading: The blank is loaded in the form die.  The hot press heats the die and the blank to the material super-plastic temperature.     Forming: Once the temperature is reached, it is accurately controlled, while the gas pressure slowly inflate the blank.     Forming: The gas keeps inflating the part to fit the die.  The material at the super-plastic temperature can allow up to 500% elongation     Release: At the end of the forming cycle, the part perfectly conforms with the die, even in its smallest details.
