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。
The effects of surface tension and die swell on the shape of extrudate during micro profile extrusion were studied and compared both analytically and numerically.
