Technical Parameters
Working Process
The working process of this 4 cavity blow moulding machine is simple and fully automatic, divided into 4 key steps to ensure stable forming:
Step 1: Preform Feeding
PET preforms are automatically conveyed to the feeding rail and clamping mechanism, realizing continuous feeding without manual handling.
Step 2: Preform Heating
Preforms enter the infrared heating oven with uniform temperature control, ensuring plasticity for subsequent blowing—essential for the pet bottle blowing machine to produce high-quality bottles.
Step 3: Blow Molding Forming
Heated preforms are sent to 4-cavity molds; high-pressure air shapes them to fit molds. The full-automatic Blow Machine precisely controls pressure and time, ensuring uniform wall thickness, especially for 1500ml-2500ml bottles.

Step 4: Bottle Discharging
After forming, molds open automatically, and finished bottles are conveyed to the next process, completing the cycle and improving efficiency of the pet machine 1500ml 2500ml.
