Abstract

This invention provides a method for forging and extruding handlebar vertical tube and product made by the same, including the steps of: opening a first mold; introducing a metal blank material; forging to form a semi-finished blank material; removing the semi-finished blank material; opening a second mold; extruding to form a final product; and removing the final product. By adopting the above method, a handlebar vertical tube is integrally configured to a particular shaping with better strength, to an increased clamping width to ensure steady connection with the handlebar and the front fork at its clamping portion.
