聚碳酸酯螺旋式挤出吹塑机头的实验研究

Research of Polycarbonate Spiral Extrusion Blow Die-head

简述了目前聚碳酸酯挤出吹塑机头存在的常见缺陷,自行设计一套新型的螺旋式挤出吹塑机头,并用于挤出吹塑聚碳酸酯饮水桶。研究发现,该新型的螺旋式挤出吹塑机头具有清洁性好、无熔合线、无黑点、壁厚均匀以及生产损耗小的优点。

Normal defects of polycarbonate extrusion blow die-head were presented. A new spiral extrusion blow die-head was designed and manufactured for extrusion blow molding polycarbonate water barrels. It was tested and proved to have advantages such as good cleanness, none welding-line, none black point, even wall-thickness distribution and lower production cost, etc.
