Stretch Blow Molding Machine - High-performance Pet Production, Efficient Two-stage Injection Stretch Process

With the help of diligent and adept professionals, our organization is prominent Exporter, Manufacturer & Supplier of Stretch Blow Molding Machine in Jining, Shandong, China. Stretch Blow Molding machine commonly used to producing the PET drink water bottle or other containter as two-stage processing. In the two-stage injection stretch blow molding (ISB) 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 one end. These preforms are packaged, and fed later (after cooling) into a reheat stretch 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.
