摘　　要：在 3C产业中 ,各项产品之零组件具有高精度、小型化、轻量化及使用量大等特点。随着产品的轻、薄、短、小发展趋势 ,使得对内部零件之要求趋向更少化 (二合一 ;三合一 )或更薄小化 ,造成零件的形状更趋复杂 ,且在形状、厚度及精度上有更多之变化要求 ,这些特殊的要求已非传统的冲压生产技术所能达成 ,而冷锻生产技术则又不具备大量生产的经济性要求。板材冲锻复合成形技术即是为了达成此种零件生产特性之要求而开发的。本文以实际开发案例介绍此技术 ,包含工艺规划、模具设计。Many parts or packages of 3C products are originally small?light?precise and large\|scale.But with the latest developing tendency of such products,the smaller and thiner parts(that means 2 conbine into 1 or 3 conbine into 1)are required.This situation caused the part contour more complicated and brings more variable requirments to the part shape?thickness and working precision.Certainly,The traditional stamping technologies could'nt reach all these particular requirments,and get the cold forging technology could'nt accord with the economic requirments in large\|scale production.In order to find a way that could reach the productive characteristic requirments of such a kind of products,the compound stamp\|forge technology was being developed.In this paper,the new technology with two practical developed examples are intruduced,including technology layout?die design?equipment requirments and attention events on output.
