3. Partnership
AEM has developed novel patented technology to drastically increase maximum strain and
decrease cycle times during forming by an order of magnitude
TRL 8 demonstration is happening early spring with commercialization to follow immediately after
Currently working with early adaptors in industries including: Marine, Aerospace, Automotive, and
Consumer Goods
Key highlights:
Forming up to 20x faster than traditional SPF
More complex and detailed features than traditional SPF
Able to make traditional stamped parts in one process instead of progressive die or multiple
parts with welding
5. Why Improve SPF ?
Slow forming time
3 - 25 minutes - Automotive panels
1 - 8 hours - Aerospace panels
How to Improve SPF ?
Improve Forming Tool “Gas” – compressible fluid
Gas can be Oscillated to act as a Hammer
In Process Dynamic Stress Relieve with minor gas oscillations
6. In Process Dynamic Stress Relieve
Each generated minor gas oscillation deforms the material
and subsequently allows for partial stress relieve

OESPF SPF
Time to reach 50% thickness
OESPF process improves material grain boundary sliding mechanism
through in Process Dynamic Stress Relieve leading to more homogenous
stress distribution with the following potential benefits:
• reduces forming time
• increases elongation
• improves thickness uniformity
• reduces localized peak stresses
• operate at higher strain rates
• more economical process

Prototype Tool
Pressure Time curves
Reduce until reach
50% thickness reduction or
0.05 /s strain rate
Peak Strain Rate is measured anywhere in the part during the forming process not at one location
Pressure Time curves
Reduce until reach
50% thickness reduction or
0.05 /s strain rate
Peak Strain Rate is measured anywhere in the part during the forming process not at one location
OESPF
Uses different generated pressure time curves that are reduced until we reach
50% thickness reduction or
0.20 /s strain rate
Part is formed in 8 seconds of the 16 second forming cycle
OESPF
Uses different generated pressure time curves that are reduced until we reach
50% thickness reduction or
0.20 /s strain rate
Part is formed in 8 seconds of the 16 second forming cycle
Future tool modifications are planned with more complex part surface geometry with detailed features and sharper corners
OESPF process allows for more uniform thickness distribution
