| Abstract: | During producing net-shaped investment casting directional blades for engine, through analyzing origination of deformation, determining the measures of preventing deformation, designing rational gating system and combination clamping device as well as strengthening control, deformation of super-thinned fine-long directional net-shaped blades was eliminated, and the dimensional precision of the blades was improved. Finally, the net-shaped blades for engine meeting requirements were produced successfully. |
