Is a kind of liquid die forging for the casting method. Is a dedicated die-casting die-casting die forging technology of die forging on complete process. Its basic process is: first low-speed or high speed casting filling liquid metal into the mold cavity, the mold cavity surface activity, it with the liquid metal cooling pressure forging process, both eliminate shrinkage cavity, shrinkage defects of blank and the internal organization in the blank forging state crushing grain size. Blank of the comprehensive mechanical properties are improved significantly.
