6 Cavity 3L High Speed Automatic Blow Molding Machine / Pet Bottle Manufacturing Machine

For standard 3L large PET bottles, the stable production capacity reaches 8000-9000 BPH. Compared with 4-cavity machines, it greatly improves production efficiency while maintaining stable blowing quality for large-volume bottles.

3L large bottles require stable blowing pressure and cooling time. The 6-cavity model is the most cost-effective choice for large bottle mass production. It offers higher output than 4-cavity, lower defective rate and lower auxiliary equipment cost than 8-cavity, balancing productivity and stability perfectly.

This machine supports PET bottles from 500ml to 3L, widely used for edible oil bottles, mineral water bottles, big juice bottles and large-capacity daily chemical containers. Different bottle sizes can be realized by replacing blow molds.

Overall dimension: L6.2 X W1.9 X H2.9m. It occupies reasonable space, smaller than 8-cavity large bottle machine, easier for workshop layout and production line arrangement.

Yes. Standard universal interfaces are reserved. It can perfectly match automatic preform feeders, filling machines, capping machines, labeling machines and conveyor systems to form a complete unmanned production line.
