    super forging hydraulic press is an indispensable and important equipment for machinery manufacturing. It is basic equipment for the manufacturing of aerospace industry . It is also widely used for the manufacturing of other important industrial sectors which also need large forgings, such as the turbine wheel , large gas turbine wheel forgings, all kinds of engine blades, large-scale marine forging parts, forging parts with a large power station, pressure vessel forgings, and so on.

    super forging hydraulic press is so important to aerocraft industry that one country can not forge large-scale material and conponent without it.So, without it ,any of the following birds can not be built.
    [​IMG]


    Russia now has the world biggest super forging hydraulic press which is 75000-ton-class.Frenchmen has no such big super forging hydraulic press ,so Frenchmen have to have the land gear molding of A380 made in Russia.
    [​IMG]

    now, most of super forging hydraulic machines are owned by USA,Russia and European. that is why they have most advanced aircraft industry in the world.
    [​IMG]

    China plans to build its first commerical big plane C919 and big miliary transport plane.Chinese current super forging hydraulic machines are not powerful enough to build such big plane.
    that is why CHinese are now investing billions of dollars on developing global biggest 80000-ton-class super forging hydraulic machines.

    Chinese C919
    [​IMG]
    here are the super forging hydraulic machines Chinese owns now. they are too small to build big plane such as C919 or Boeing 747.

    large-scale Marine Crankshafts is the key component of monster tankers and super aircraft carriers.

    the engines drive the crankshafts directly,then the crankshafts drives the propellers directly.then the monster tankers or super AC can have the driving force.
    the large-scale crankshafts for monster tankers or Super AC

    the large-scale propeller of US SUper aircraft carriers
    [​IMG]

    because the large-sale crankshafts for monster tankers and super AC is sooo big that only a few countries can machine it.

    To manufactur monster tankers and super AC by itself, CHina has worked out the key machining equipment of such large-scale crankshafts.
