SPF - Superplastic Forming

Complex Design by Superplastic Forming

FormTech
The development of superplastic forming is closely combined to the technical progress and the high quality demand of aerospace manufacture.
Years of experience are the guarantee to develop the most econonical operation along with the optimized technical solution.
With our laboratory hot press and our successful tooling concept we verify
the process and are able to produce in small batches.
Our advanced SPF-technology allows new and innovative solutions for sophisticated customer requirements:
  • volume oriented objects with highest complexity made from high strength alloys

 

 

SPF: a method for economic manufacture of thinwalled three dimensional structures

 

SPF-Technology: extreme high yielding is the characteristic of superplastic forming. Titanium reaches this condition in a hot press when heated up to 900 °C. With application of comparatively low gas pressure, the material forms over the shape of the forming die.

 

Extremely thinwalled but rigid design is possible. Our process is governed by specifically developped SPF-parameters and an advanced tooling concept. This method allows us to adjust the panel thickness as required.
