ABSTRACT:
A method for making a crystallized bottleneck of a polyester beer bottle is provided. The bottleneck has no machined screw threads and a length of 0.5-35 mm. To manufacture the crystallized bottleneck, an uncrystallized blank of the bottle is placed in an air-condition environment and a crystallizer is preheated before crystallization. A bunker is loaded with the uncrystallized blank, which is delivered to a blank horse's head via a conveyor belt. A bottleneck portion of uncrystallized bottle blank is then sent into a crystallizer to heat it at high temperature and crystallize it via an arbor transmission chain. The polyester bottle blank having a crystallized bottleneck portion is discharged through output blank horse's head and delivered to another conveyor belt to cool and shape it.
