Abstract:The problems of isothermal forming efficiency, thermal efficiency, production efficiency were stated,and the problems of the manufacturing, service life, efficiency of the tooling and die were introduced. Automatic continuous feeding and heating system was proposed to use to reduce heat loss and idle time of the equipments. The integral forging for precise batch forming, assembly and disassembly, heating and cooling of tools on two platforms of press were used to improve production efficiency; and the design of core die with frame die, different sand molds and using vacuum casting process were proposed to solve the problems of the die’s casting and service life. The development trend of isothermal forming was introduced,and the way to realize digital isothermal forging was put forward.
