摘    要：复合包套由金属套与隔热片组成，运用复合包套模锻可获得理想的锻造温度，降低变形抗力，细化晶粒；消除锻造裂纹，改善锻件性能，提高模具寿命。西南铝加工运用复合包套模锻新工艺，首次在国内实现了大型难变形金属精密锻件的生产，该文主要介绍其规律和实例。

Abstract: A new technology of die forming, with a metallic jacket intercalated heat insulating sheet to envelope the hot metallic work-piece and keep its temperature to be decreased only a little, has been developed and used to produce large work-pieces. The results showed that this technology could obtain ideal forging temperature, reduce forging loads, fine crystal grains, eliminate forging cracks, improve the properties of the forged work-piece and lengthen the service life of the mould. For the first time, some large precise forged work-pieces of unmanageable metals are produced in China.
