摘要

Hydroforming is gaining ground in the manufacture of many automotive components, such as pillars, frame rails, and engine cradles. Automakers are finding hydroforming advantageous for forming many smaller parts also. The process is useful for manufacturing an automobile fuel filler tube, which is the expanded portion of a fuel filler assembly where a fuel nozzle is inserted. Fuel filler tubes currently are manufactured from carbon steel tubing, which is expanded using mechanical forming techniques. The filler tube then is welded to a section of tubing that is bent to the shape required by the vehicle's design.
