2500bottles Per Hour Pet Stretch Blow Moulding Machine

Bottle Blow molding machine

Description and Advantage:
Bottle Blow molding machine is specially designed by us and is our patented product. It is upgraded from semi-automatic PET Bottle blow moulding machine. Compared with semi-automatic, the capacity has been increased a lot which can achieve 2500Bottles per hour and labor cost will be reduce a lot; Compared with full-automatic, the cost is only half. We strongly recommend this model.

How Bottle Blow molding machine works:
1. Preforms are loaded into the hopper, which holds up to 3000 preforms at a time.
2. An elevator moves preforms up to a gravity-based sorter, which aligns preforms on a conveyor.
3. Preforms are then aligned and loaded onto a chute, where they are gravity-fed into the preform holders. Four preforms simultaneously move through two parallel heat tunnels, each with eight heat zones and two quartz heating elements.
4. The preforms move through the heat tunnels, where they are heated to the optimal blowing temperature prior to entering the molds.
5. From the heaters, preforms are loaded into the custom-designed molds where four bottles are blown at a time. A pressurized liquid chiller keeps the mold temperature in a controlled range to ensure that consistently high-quality bottles are blown.
6. The blown bottles, still in the preform/bottle holders, are placed on the exit conveyor.
7. Bottles are conveyed out of the Blow Molder and into collection receptacles, then moved to storage areas to await processing on the production line.
