SEPPA SSB-2D (Auto Drop) PET Blowing Machine
OverviewofSEPPASSB-2D(AutoDrop)PETBlowingMachine
In high volume rigid packaging production, maximizing mechanical efficiency while minimizing human intervention is critical for maintaining container quality. The SEPPA SSB-2D (Auto Drop) is an industrial grade engineering solution that balances high speed kinetics with precise material handling. As a premium auto drop pet blowing machine, the SSB-2D features a servo integrated automated preform to bottle drop mechanism designed to streamline downstream operations.
Unlike traditional manual or semi automated systems that introduce variability and structural contamination risks, this auto drop pet blowing machine operates via closed loop automation logic. This ensures that every preform undergoes identical thermal conditioning and mechanical stretching profiles.
The equipment was designed by Seppa Solutions as the foundation structure for turnkey lines. This is because this equipment has been designed to integrate heavy steel structures with mechanical parts to ensure that there are no harmonics in high speeds. Through using this machine, the manufacturer ensures that there is wall thickness consistency and fewer rejects.

Methodology:HowtheAutoDropPETBlowingProcessWorks
The transformation of an amorphous polyethylene terephthalate (PET) preform into a biaxially oriented container requires precise control over thermodynamics, timing, and pneumatics. The auto drop pet blowing machine manages this journey through automated stages:
Preform Sorting and Orientation
Raw preforms are deposited into a bulk hopper elevator, where a mechanical sorting wheel aligns them with the neck finish facing upward. They then slide down a gravitational feed rail into the loading star wheel.
Infrared Thermal Conditioning
The preforms enter a multi zone infrared (IR) heating oven. To ensure an even temperature equilibrium across the material geometry, individual zones regulate the heating profile of the preform finish, body, and base. Simultaneously, continuous rotation of the preform core holder prevents localized overheating or material degradation.
Servo Driven Transfer and Clamping
Once the preform reaches its optimal material temperature typically between 95C and 115C the machine transfers it into the mold cavity. The proprietary drop mechanism aligns the preform with the mold centerline before the high pressure pneumatic toggle clamp locks the mold halves together.
Biaxial Stretch Blow Molding & Auto Drop Ejection
A servo driven stretch rod descends into the preform to mechanically extend it axially. Concurrently, a low pressure air circuit (8 to 15 bar) inflates the preform, followed by a high pressure blow circuit (30 to 40 bar) to push the plastic into the mold details. After rapid cooling, the mold opens and the integrated gravity assisted servo drop mechanism releases the finished bottle onto a discharge conveyor.
This automated cycle ensures that every pet bottle blow machine output meets strict quality metrics. It stabilizes material distribution across the base and shoulder areas to maximize the container's structural integrity.
