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.

What is Super Plastic Forming (SPF)?

Strengths of Super Plastic Forming (SPF)

01. It requires only one mold, either a core or a cavity mold.

02. Capable of manufacturing the design of freely combined curved surface.

03. Capable of forming complex shapes which are difficult by cold forming processes.

04. Capable of forming large parts.

05. Reduction of parts with near net shape forming of complex shapes.

06. Low environmental impact with Non-Lead die lubes, and low noise.

Strengths of Metal Technology Co. Ltd.

01. Simulation

  • Metal Technology Co. Ltd. can perform high temperature tension tests and forming simulation in order to determine and inspect material properties before forming commences which eliminates reduces waste and costs.

02. Integrated manufacturing system

  • With our integrated manufacturing system from the initial designing of the mold to manufacturing, Super Plastic Forming, and inspection and analysis Metal Technology Co. Ltd. can control and monitor all conditions and needs.
