The blowing process of the stretch blow molding machine is divided into two processes:
The preform is irradiated by infrared high-temperature lamp tube, to make the preform body heated and softened. In order to maintain the shape of the preform mouth, the preform mouth does not need to be heated, so a cooling device is needed to cool it.
2. Blow molding
The second stage is to place the preheated preform into the blow mold, and inflate it with high pressure clean compressed air, blow and stretch the preform body into the desired bottle.
Automatic blow molding machine completes the two processes by manipulator operation, which eliminates the process of manually putting preheated preform into the blow mold. Greatly speed up the production rate.
