In order to reduce the equipment size, sometimes the large-scale forging pump press commonly used high intensity of pressure (about 35 megabars), also uses 100 megabars above ultrahigh voltage.

为减小设备尺寸，大型锻造水压机常用较高压强（35兆帕左右），有时也采用100兆帕以上的超高压。

The production of turbine blades mainly uses forging billets in small-scale production, so the forging die design requires much higher production.

汽轮机叶片目前主要采用小批量生产的锻件毛坯，其对锻造模具设计效率要求很高。
