DR-A6 One-to-Six Fully Automatic Blow Molding Machine

The DR-15L series fully automatic blow molding machine is our company's most stable two-step down-blowing fully automatic blow molding equipment. It ranges from one-outlet to six-cavity blow molding, capable of producing bottles up to 0.6 liters and 2 liters. It is suitable for blowing any shape of carbonated beverage bottles, mineral water bottles, cosmetic bottles, large-diameter bottles, high-temperature resistant bottles, and other packaging containers made from crystalline plastics such as PET and PP.

Features

1. Fully automatic human-machine interface, easy operation, stable machine operation, few malfunctions, and fast blowing speed.

2. Reasonable material selection, precision machining, and fine surface treatment for all machine parts.

3. Adopts a rotary continuous preform loading mechanism, which has high compatibility with preforms, provides stable and continuous loading, high speed, and high efficiency, overcoming the shortcomings of traditional intermittent preform loading by robotic arms.

4. Dense arrangement of preforms in the heating zone, fast and uniform heating, and energy saving.

5. 6. The chain for the heating zone's revolution drive uses an original imported chain from Tsubakimoto, Japan. This chain has precise pitch and is durable.

7. The chain for the heating zone's revolution drive is designed with a mold spring flexible tensioning mechanism, extending the chain's service life.

8. The PET Blow Molding Machine's bottle mouth is equipped with a cooling air blowing device, which can more effectively protect the preform's threaded ends.

9. The spacing mechanism is rationally designed, ensuring accurate and reliable spacing.

10. The preform (bottle) conveying mechanism uses original imported German Festo servo motors and electro-positioning systems, ensuring fast preform (bottle) conveying speed and high repeatability, overcoming the shortcomings of traditional pneumatic conveying mechanisms.

11. The cylinder-type mold-locking mechanism provides strong mold locking and stable and reliable operation.

12. The preform stretching uses a servo motor, offering fast stretching speed, accurate stretching stroke, and arbitrarily adjustable stretching stroke.

13. The blowing (exhausting) system uses original imported German Festo combination valves, offering fast blowing (exhausting) speed and long service life. Bottles can be directly fed into the filling line. The innovative conveyor mechanism ensures smooth and reliable transport.

14. Interoperability programs are installed between all operating mechanisms of the machine to protect it.
