Gas Oscillation Enhanced SPF

The Next Generation of Superplastic Forming

GO-SPF™ Isn’t Just an Upgrade. It’s a Breakthrough.

GO-SPF™ is a patented leap forward in superplastic forming. By integrating gas oscillation directly into the blow forming process, this technology dramatically improves formability, allowing for sharper radii, deeper draws, and more complex geometries than ever before. It’s built into DUNKES and Macrodyne’s SPF presses, custom-tuned to your alloys, tool design, and part geometry. The result? Faster forming, finer-grain structures, and fewer rejects. This is what the future of SPF looks like, and it’s already here.

Ground-breaking Patented Solutions

Gas Oscillation Forming System software and mechanisms are built into Macrodyne-DUNKES SPF presses and are further customized to each application according to the:

Forming part geometry

Type of metallic alloy

Tool design

Systems are engineered to generate gas oscillations of various amplitudes and frequencies inside the forming tool with each generated gas oscillation deforming the material and subsequently allowing for partial stress relief of the material during the superplastic blow forming process. This results in an improved formed material grain boundary sliding mechanism.

Gas Oscillation Enhanced SPF Advantages

The patented technology transforms the decades old conventional SPF process into the next generation providing industry-leading manufactures the following benefits.
