Development of Hot Press Machine for Superplastic Forming Technology
In most superplastic forming process, one or more sheets of superplastic grade materials are heated and forced onto or into single surface tools by gas pressure. Since the assembly includes only clamping dies, temperature chamber and regulated gas pressure to provide forming force, the assembly is easy to use for aircraft components. However, it is not easy to control process variables at high temperature. This paper presents an economic machinery method to develop hot press machine for manufacturing complex contoured components using superplastic forming and diffusion bonding technology.
