The main challenge in a polymer coextrusion process is to have a good die design prior to
the process, which can minimize the geometric errors that are caused by extrusion swell and …

In the design of coat hanger extrusion dies, the main objective is to provide a uniform flow
rate at the die exit. Previously, a multi-rheology isothermal method model for coat hanger …

Abstract The well-known Winter-Fritz horseshoe die introduced in the 1980s has been used
in polymer sheet/film extrusion die and coating die industries with success. The geometric …

In the polymer sheet processing industry, the primary objective when designing a coat-
hanger die is to achieve a uniform velocity distribution at the exit of the extrusion die outlet …

为提高熔喷装备纺丝箱均匀分配熔体的性能, 同时兼顾纺丝箱腔体制造技术与成本的要求,
提出一种使用矩形截面歧管的衣架型模头设计方法. 该方法基于Carreau-Yasuda 黏度模型 …

With regard to coating die manifolds, there has been much interest in two types of problems:
forward (or direct) problems and inverse problems. The former is designed to predict the …
