spindle head
The spindle head (or rotary spindle head) is a rotating assembly in a PET blow molding machine that holds and positions blow molds during the production cycle. It rotates continuously or intermittently to transport molds through key stages of the blow molding process:
- Preform Loading→ 2. Heating → 3. Blowing/Stretching → 4. Cooling → 5. Bottle Ejection.
It ensures synchronized, high-speed production while maintaining precision and stability.
