三层塑料容器共挤复合机头设计

Design of Coextrusion Head for Three-layer Plastic Container

本文介绍一种用两台挤出机共挤复合三层塑料中空容器机头的模具设计。为了提高机头的适应性及制品性能，对机头的结构特点、塑化性能及工艺条件作了详细的论述。

In this paper was introduced a kind of design of coextrusion head, which coextruded three-layer hollow container. In order to improve the adaptabilities of the head and the properties of the products, the structure characteristics of coextrusion head, the plasticizing properties and processing conditions were discussed in detail.
