The differential gauge forging can be made by general open die or horizontal split precision closed die.
差压计锻件可以采用普通开式模锻成形和可分凹模多向闭塞精密模锻成形。

So, it is always formed on the die-forging hammer by the open-die forging with insert mode.
液压支架中的缸底生产批量不是太大，外形多变，所以它多在锤上用镶块模开式模锻成形。

Based on the analytic results of the numerical simulation, the forming process and the mould structure for the spur-gear open-die forging were designed properly.
