this is may question, i play a pbm with the allies and see me enemy have very much trrops and airforce, I cant never produce that in my plays with the axis, what is the secret to produce larges numbers of units and planes with hig level of tecnology ?

Manage your losses and advance enough to capture cities and get lots of PP's! Getting your Industry tech up also helps for the Germans. In my games as Germany, in 1943 it is possible to be producing at ~170 pts a turn (about 35 as the Italians), so as long as you are not suffering massive losses, it is possible to continue to grow in strength significantly.

Generally its your fate as an axis player.
While allies can rely on many weak and expendable troops, you have to operate with smaller and better quality combat groups, because you have limited manpower, PP, and time itself (allies have huge convoys, USA away from combat and huge USSR, while you sometimes spend all earned PP to repair front line forces).
But technological advantage + good tactics (avoid looses) will lead together to growth of your army.
