自上世纪拉伸吹塑技术的诞生，伴随饮料、化工等行业快速发展，使这项技术成功推广到世界各地。目前，横向环形拉伸吹塑技术研发较少，市场开发潜力较大，伞形PET瓶坯设备工艺采用推力杆横向环形展开推动弧形叶片，伸缩杆推进补充完成瓶坯内腔模具，合模注射成型为瓶坯，伞形PET瓶体设备工艺采用伸缩杆依序依角度做拉伸运动至瓶坯内底部，伸缩舌伸出完成环形闭合状态，伸缩杆伸缩舌同步做环形拉伸完成伞形瓶体工艺过程。帽式饮品展现吹塑制品多功能多用途性，推进拉伸吹塑技术向高端发展。%Since the birth of the stretch-blow molding technology in the last century,the technology has successfully spread all around the world along with the rapid industrial development of beverage,chemical and other sectors. Currently,there has been little research on the technology of lateral annular stretch-blow molding and the market potential is large. The technology of the umbrella PET bottle preform equipment adopts the annular lateral thrust rod to drive the curved vanes and the telescopic rod drive supplement to complete the cavity preform mold to form the bottle performs with the help of clamping injection molding; the technology of the umbrella PET bottle uses the telescopic rod to perform the stretching sequentially according to the angles all the way to the internal performs bottom; the telescopic tongue protrudes to complete the ring closure; the retractable telescopic pole and the telescopic tongue stretch synchronously to complete the circular umbrella vial body process. The hat-style drinks demonstrate the multi-functional versatility of the blow-molded products,and the technology will promote the stretch-blow molding process in the direction high-end development.
