In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory.

The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.

影响产品美观的主要原因是在平压平自动模切机上进行模切加工时需要将靠叼口边的刀多敲破几个小口，才能顺利地将模切后的成品从机器中拉出来，敲破的小口体现在模切后的盒上是边缘不光滑。

Please not that a 250 mm wide die opening will produce a film or sheet with less width since you have a "neck in" effect when you pull out the melted resin from the die before it reaches the surface of the chill roll. the width you can achieve depends on the melt strength of the resin as well as the distance between the die lip opening and the chill roll. but in general, about 80% of the die opening width can be achieved.

注意：250毫米宽开口的模头只能获得小于此宽度的薄膜或片材，因为当熔体树脂被从模头拉至冷辊上时会产生&颈缩&效应，最终获得的实际宽度依赖于树脂的熔体强度以及模唇开口同冷辊之间的距离，但总而言之，可获得模头开口宽度80%的产品宽度。
