Methods for forming seamless and jointless metal parts suitable in a manufacturing environment are disclosed. The metal parts can be used in the manufacture of electronic devices and accessories of electronic devices, such as connectors. In particular embodiments, the methods involve forming a seamless cylindrical tube. The seamless cylindrical tube can then undergo a series of shaping processes that retain and exterior seamless surface of the tube. In some embodiments, the shaping processes include a hydroforming process. The methods can be performed without the use of dovetails and other types of visible joints that can complicate the manufacturing process and result in a part with aesthetically unappealing visible joints and seams.
