The problem with toggle clamped injection moulding machines is with only the hydraulic pressure meter available there is no way to set an accurate clamping force when the mould is installed and to maintain it constant during injection 用曲轴式锁紧机构的问题是， （因为）只有液压压力测量计可用（用于测定锁模力） ， （所以）无法在模具安装后设定精确的并在注射过程中维持不变的锁模力。
