Method of preparing hydroformed metallic golf club shafts
TLDR
In this article, a method for preparing a golf club shaft, set of shafts, or golf clubs having shafts which have been produced by a process that includes a hydroforming step is presented.Abstract:
Method for preparing a golf club shaft, set of shafts, or golf clubs having shafts which have been produced by a process that includes a hydroforming step. By utilizing a hydroforming prosses step, a metal or metal matrix composite golf club shaft can be formed into a variety of configurations or shapes heretofore not possible and can include hydroformed ornamental design features.read more

Multi-stage tube forging method for disproportionally enlarging an end section of an aluminum alloy tube of a bicycle frame part
TL;DR: In this article, a multi-stage tube forging method for disproportionally enlarging an end section of an aluminum alloy tube of a bicycle frame part is described, which involves drawing the tube to form a thin section and a thick end section, and then enlarging the cross-section of the thick end sections of the tube by forging the tube in such a manner that the wall thickness after being enlarged is substantially the same as that of the thin section.

Hydroformed tubular member and method of hydroforming tubular members
TL;DR: Tubular members for use in vehicle frames are easily and economically produced using a hydroforming process in which a high pressure fluid is presented to the interior of a tubular member, thus causing the tube to expand to meet the interior walls of a forming die as discussed by the authors.
