AEM Power Systems Inc was established in 2007 and provides R&D services, Engineering services, Consulting services, Industrial Heat Transfer Systems, and Gas Oscillation Forming Systems for Automotive and Aerospace industry.

AEM is developing world leading advanced manufacturing capability in the field of superplastic blow forming of various metallic alloy sheets into highly complex geometrically shaped panels through advancement of state-of-the-art disruptive innovative solutions involving CFD, FEA simulation-modelling, engineering, unique industrial heat transfer systems, and innovative gas oscillation forming technology to transform current superplastic blow forming process not changed in the past many decades to a significantly improved oscillation enhanced superplastic blow forming process.

Since 2012, AEM has been continuously focused on research, development, and engineering of gas oscillation forming technology for Oscillation Enhanced Superplastic Blow Forming process.  This unique and innovative technology involves the development of a Gas Oscillation Forming System that generates and transfers gas oscillations of various frequencies and amplitudes into a forming chamber of a superplastic forming tool. Gas oscillation forming system has no moving parts that can fail in high temperature environment and has the potential to significantly improve formability of light weight metallic sheets such as aluminium, magnesium, titanium, and possibly other alloys when compared to traditional non oscillating gas filling method. Each generated gas oscillation deforms the material and subsequently allows for partial stress relief during the Oscillation Enhanced Superplastic Forming process which leads to improvement in material grain boundary sliding mechanism, faster forming speed, improved thickness uniformity, and longer elongation.

AEM has been granted US and Canadian patent for the use of the supersonic fluidic oscillators in the superplastic forming.  Additional patent applications related to gas oscillation technology have been filed. These key IPs will enables AEM to develop innovative Gas Oscillation Forming Systems and protect this advantage well into the future for superplastic forming of various metallic alloy sheets such as:

  • Aluminium based alloys

  • Magnesium based alloys

  • Titanium based alloys 

  • Possibly Nickel based alloys

  • Possibly Intermetallics

Supersonic Fluidic Oscillator

SFO is a device that can produce a self-sustained, bi-stable gas oscillating flow at its output from a supplied steady inflow. This device is capable of superimposing large pressure fluctuations on the flow through a device without the necessity of having any moving parts. The lack of moving parts makes this device superior to conventional moving-part valves in high temperature and various frequency applications. SFO has considerable number of advantages, such as a wide range of operating frequencies and amplitudes, robustness to shock and vibration and fault-tolerance over a wide range of operating conditions. The absence of any moving components makes it virtually maintenance free. SFO comprises of multiple flow channels and volumes arranged in different sizes and geometrical shapes.  SFO can be engineered to achieve a bi-stable continuous oscillation output of desired amplitudes and frequencies for specific SPF tool and forming material.

Gas Oscillation Forming System

Each GOFS is SPF tool and forming material specific.  GOFS consists of specifically engineered SFO, various sensors coupled with controls and driven by patented algorithm to achieve oscillation enhanced superplastic forming manufacturing process for the selected forming material.  GOFS is specifically engineered to target forming material higher than normal operating strain rates by subjecting the material to specific oscillation frequencies and amplitudes. Each generated oscillation at particular frequency and amplitude deforms the material and subsequently allows for partial stress relief of the material during the forming process.  

Benefits of forming parts with GOFS during OESPF process:

  • Higher quality

  • Higher elongation

  • Reduce forming time

  • Thinner produced parts

  • Improved thickness uniformity

  • Manufacture more complex geometrical shapes
