The main problems in the current technological process for manufacturing forging die for air valves were analyzed. The research by experiments on the electrolytic machining of forging die for air valves with high-frequency narrow-pulse current and the result of forging the air valves in the trial production were introduced. The high machining precision, high surface quality, high production efficiency of this new processing technology was proved. Its prominent advantages greatly shortened the production cycle, increased the life of the die and lowered the cost for the die. Several points on the technical innovation for the die manufacture were put forward.
