摘要
Abstract
The mould design of double-layer co-extruded composite plastic pipe head was introduced. In order to improve the density of composite pipe and materials processing performance) the optimal design of the structural features for the head was carried out. and the two-choke device was added to the mandrel. The results show that, when the material flow over the two-choke mandrel, its density increases, and the plasticizing properties are good. Besides, the extrusion is stable, internal and external pipe surface gloss is good and the strength is high.关键词
