The invention relates to a machining process for a door handle, which comprises the following steps: 1) discharging and turning; 2) flattening; 3) molding at a right angle of 90 degrees; 4) molding the door handle; 5) normal temperature cold extruding; and 6) performing the steps of trimming, shaping and the like. The invention innovates the manufacturing process for the aluminum door handle, suchthat the surface of the handle can have exquisite styles, patterns and flower types, and can also have better electroplating and oxidizing effects. The machining process for a door handle has excellent economic and social effects, is lower in cost, better in performance and higher in strength compared with zinc alloy, and is an initiative process.
