Abstract:
     The invention relates to an integrated compress molding method of asymmetry integrated element. It uses concave and convex moulds, to heat, compress and mold the blank. It is characterized in that: according to the position and size of cam on the element, designing the blank with non-uniform thickness; the blank is arranged in the concave mould with a deflection as S; the thicker part of blank or the deflected part is arranged with the edge that needs more metal (the edge with cam); it controls the metal flux and flow direction, via said non-uniform thickness or the deflection amount S, to fill the mould chamber with metal to mold the element. The inventive mould is integrated, with stable operated and simplified process. The element can be compressed molded in one time, to reduce the producing cost; the product has high size and surface accuracy, and high material utilization.
