a unique process for forming complex shapes
Combining hydroforming and press shop facilities, MSM aerospace fabricators has developed its bulge forming technique to a fine art.
Bulge Forming is a process that involves expanding fluid in a rubber bladder, or bung, within a cavity die tool containing a sheet metal blank (cone or tube) to create a pre-determined shape reflected by the inner contour of the cavity die tool. It is an axial loading, cold forming process and is typically used to form cylindrical and spherical components from super alloy materials. The advantages of this process are that it is capable of producing complex shapes, with non-symmetrical features if required, and with uniform wall thickness.
