1) post-extrusion swell
挤后膨胀
2) die swell
挤出膨胀

It was found that the die swell ratio (B) and the entrance pressure drop (ΔPENT) increased with increasing the diameter ratio (DR/D) of the reservoir to the die , and the relationship between ΔPENT and B wasbasically linear : B=B0 +KΔPENT, where the coefficients B0 and K were related to the experimental conditions , which characterized the el.
结果表明,试样的挤出膨胀比(B)和入口压力降(△P_(ENT))随着料筒与口型直径比的增加而增大,△P_(ENT)与B大致呈线性关系:B=B_0+K△P_(ENT),其中,待定系数B_0和K与实验条件有关。

补充资料：K311八轴挤芯机操作规程
1、遵守铸造设备通用操作规程。
2、检查三角皮带的松紧度与磨损情整，如过紧、过松，或磨损严重，应予调况或更换。
3、先点动试车，然后空运转2-3分钟，检查传动系统（电动机、减速器）以及压杆与塞杆的运动是否正常，确认一切正常后，方可进行生产。
4、工作后，清理设备时，要特别清理料槽中和套筒里的积砂。
