What is Super Plastic Forming (SPF)?

Superplastic forming (SPF) is based on the fact that some alloys can be slowly stretched well beyond their normal limitations at elevated temperatures. The higher temperatures mean the flow stress of the sheet material is much lower than at normal temps. This characteristic allows very deep forming methods to be used. Superplastic alloys can be stretched at higher temperatures by several times of their initial length without breaking; for example 100% and 300% for aluminium and titanium alloys respectively. Superplastic forming can produce complex shapes with stiffening rims and other structural features as well.
Key Advantages of SPF:
Single-Tool Forming:
Achieve high-precision components using a single mold. In conventional molding processes, both male and female molds are required to create the product shape. However, in superplastic forming, because the material is highly elastic, molding can be done using only one mold, which allows for significant reduced tooling costs and production time.
Shaping Beyond Limits:
High-temperature forming enables complex geometries unattainable with conventional cold-forming methods.
Integrated Assembly:
Consolidate multiple components into a single formed part, streamlining manufacturing processes and reducing assembly costs.
Large-Scale Capabilities:
Manufacture oversized components seamlessly, meeting the needs of aerospace and other industries requiring large, integrated parts.
Enhanced Aerodynamics and Aesthetics:
Produce smooth, curved surfaces ideal for automotive and aerospace applications.
