a、是在采用简单动作匣钵成型液压机上配置多动作模架和压模;
Powder compacts with more than 3 steps along the height direction and high density and precision can be pressed. The precision of the compacts is mainly affected by the die frame and the die itself. When demolding, each step of the compact can be supported by the relevant die punch until the compact comes out of the female die, which greatly reduces the risk of the weak section of the compact being damaged;
b、是在多动作匣钵成型四柱液压机上配置简单压模;

It is usually possible to economically press three steps along the height direction and the density of low and medium compacts, and the accuracy of the compacts in the pressing direction is directly affected by the elastic motion that may be generated by the entire hydraulic press.
From the manufacturing of sagger forming hydraulic press and die, the former only needs a simple hydraulic press. Although the die structure is complicated, multi-action universal die base and universal die parts can be designed, and each hydraulic press can be equipped with several sets of universal die base. The latter has a simple die structure, but requires a multi-action hydraulic press with a complex structure, which is convenient for replacing and maintaining the stamping die and improving the service life of the stamping die, easy to take the material, improve the safety of the material.
