How Do Injection Stretch Blow Molding Machines Work ?
Stretch blow molding is mainly used to mold the hollow objects such as cola bottle and short shape parts. During the process of injection stretch blow molding, it is injected the material into a mold to form a preform. The Blowing rod is pushed into the preform before stretch, and then the preform is stretch blown immediately into a plastic bottle by using high-pressure air......
Three Work Processes of Injection Stretch Blow Molding Machines
We can divide the work process of injection stretch blow molding machines roughly into three steps:
- Process-direct heat conditioning system
- Process-molding
- The final station
