Injection Stretch Blow Molding
In the two-stage injection stretch blow molding process,the plastic is first molded into a “preform” using the injection molding process.These preforms are produced with the necks of the bottles,including threads(the”finish”)on the end. These preforms are packaged,and fed later(after cooling)into a reheat blow molding machine.In the ISB process,the preforms are heated(typically using infrared heaters) above their glass transition temperature,then blown using high-pressure air into bottles using metal blow molds. The preform is always stretched with a core rod as part of the process.
