Operation Process

1. Preforms are conveyed from the storage hopper to the automatic unscrambler, where they are orient and fed to the heating zone through a gravity feed rail.
2. Individually controlled infrared lamps, positioned along the perform path provide longitudinal differential heating and uniform heat penetration, optimizing the temperature throughout the perform.
3. The system checks the perform temperature by using sensors. Each perform temperature is compared to the preset temperature data. If temperature changes are needed, the system can automatically change the infrared lamp settings.
4. Special grippers pick up the heated performs
5. and position them in the stretch blowing stations.
6. In the stretch blowing stations, performs undergo two stages:first stretching and preblowing, then blowing by compressed air. At this point, performs are transformed into bottles.
7. Grippers transfer the blown bottles to the filling station or storage silo (8).
