Abstract：

In view of the feature of filter shell body and the formability of HPb59-1 brass,the warm forging process was adopted to manufacture the precision forgings of shell body for the microwave communication apparatus.The surface coarseness of HPb59-1shell body inner contour processed by the warm forging technology reached to Ra0.8～1.6μm and the bottom round angle was less than R0.2mm.The chief advantages included the good surface quality,closer tolerance and net-shape-forming of the shell body by this method,which can be satisfied with the requirement of shell body,because the warm forgings had no defect,such as crack,fold,flash and air hole etc.The shell body had a higher telecommunication capability.
