Abstract

Neck-in during melt casting of polymeric film and extrusion coating along with the related issue of edge bead formation, has been widely studied. However, one aspect of this problem that has received relatively little attention is empirical correlations for the thickness profile near the edges of the sheet. The correlations given here may prove useful for industrial operations as well as provide benchmarks for numerical studies of the myriad factors that influence neck-in.

熔体铸造厚度分布的简单相关性

聚合物薄膜和挤出涂层在熔融铸造过程中的缩进以及相关的边珠形成问题已经得到了广泛的研究。然而，这个问题的一个方面，已经收到相对较少的关注是经验的相关性厚度轮廓附近的边缘板。这里给出的相关性可能对工业操作有用，并为影响颈入的无数因素的数值研究提供基准。
