No-draft forging

A forged shape with extremely close tolerances and little or no draftThe necessary taper on the side of a forging to allow removal from the dies; also applies to the die impression. Commonly expressed in degrees as the draft angle. As applied to open die forging, draft is the amount of relative movement of the dies toward each other through the metal in one application of power.... More, requiring a minimum of machining to produce the final part. Mechanical properties can be enhanced by this closer control of grain flowFiber-like lines appearing on polished and etched sections of forgings that are caused by orientation of the constituents of the metal in the direction of working during forging. Grain flow produced by proper die design can improves the mechanical properties of forgings.... More and retention of surface material in the final component.
