Bulge forming is a method of forming parts by expanding from the inside. Utilization of this process enables to offer cost and quality benefits to its customers. Triumph Components-San Diego, Inc. could provide a family of bulge cases ranging in size from 3" up to 65" in diameter. EEA is the distributor in the Asia Pacific region of Triumph Components, a aviation segment company of the Triumph Group, Inc. Triumph components is successfully forming such shapes as circular to rectangular transitions and elliptical shapes with integral convolutions. Triumph Components is also successfully bulge forming acoustic suppression material with minimum distortion to the acoustic properties. Bulge forming also allows repeatability and close tolerance consistency. The part is stretched beyond its yield point to the desired finished part dimension by the application of controlled hydraulic pressure within a pressure chamber. Additionally, extremely close tolerances can be held. For example, Triumph Components is successfully producing a jet engine primary exhaust nozzle made from .05 Inconel 625 with a finished size of 40" in diameter and 30" long --to a tolerance of +/- 0.015" in critical exhaust gas flow areas.
