1., the shape of the parts is simple and avoid complex shapes such as long and complex branches and multi-directional bending.
2. the shape of the parts is symmetrical as far as possible so as to make the forging die and equipment evenly stressed and prolong their service life.
3. the surface perpendicular to the parting surface of the part can avoid grooves and holes as far as possible so as to remove the forgings easily.
4. high avoid thin wall, rib, deep hole and large diameter flange to reduce metal mold resistance;
5. forged welded composite structure can be used for complex parts to simplify die forging process and reduce reject rate.
