大直径塑料管道成型工艺的研究进展

Progress in the Research of Forming Process of Large-diameter Plastic Pipes

目前,大直径塑料管道的成型方法主要是挤出成型和缠绕成型,国内外的学者也发明了注塑-挤出成型和组装成型等方法。然而,利用这些成型方法成型大直径管道均存在一定的局限性。针对这些成型方法的局限性,本文提出了一种基于增材制造技术与传统挤出成型工艺的大直径塑料管道成型新工艺,即聚合物熔体喷射堆砌成型,并对该工艺进行了简单的介绍。

At present, the main forming methods of large-diameter plastic pipes are extrusion molding and filament winding. Some domestic and foreign researchers have also found some other forming methods like injection-extrusion molding and assembled formation. However, all of these methods have their limitation. Aimed at these limitations, the polymer melt spouted- accumulated forming technology based on additive manufacturing technology and extrusion molding technology has been put forward and briefly introduced in this paper.
