the preform may be further shaped to bring it closer to the final configuration in a"blocker die",which ensures proper distribution of material within the die.excess material is allowed to run out between the dies into a flash.before forging in the finishing die the excess material may be removedin a trimming die.A thick flash in the finishing die means high pressure within the die,which assures proper die filling.excessive pressure may break dies or reduce their life,and some control on this may be exercised by proper control the flash land.
the geometry of the preform and the forging dies must promote smooth materialflow.therefore,a parting smooth material flow.therefore,a parting line is chosen with proper consider of the fiber structure of the located the die walls are given sufficient draft to permit removal of the forging from the die cavities.fillets and corners must be given appropriate radii to ensure smooth material flow and long die life.

预制件可以在铸锻模中进一步成型达到最后设计要求, 以确保材料在铸锻模中合理分布. 多余的材料从铸锻模之间溢出形成飞边, 在进行精密锻造之前, 多余的材料在冲模中去掉.在精密锻造中, 厚的飞边需要较高的锻造压力, 保证材料较好地填充铸模, 但过高的压力可能损坏铸模或减少其使用寿命. 因此,在锻造过程中,要控制飞边的大小,保证合适的锻模压力.
要求预制件的几何形状和锻模保证锻造材料分布流畅. 也容易脱模, 考虑选用纤维结构模缝线, 模壁要有足够的拔模斜度,以保证锻造容易从锻模中取出. 锻模要有一定的内圆角, 保证锻造材料的延展和锻模的寿命.
