Overview
Automatic PET Stretch Blow Molding Machine — Specifications & PET Bottle Production
Buyers sizing an automatic pet stretch blow molding machine for beverage, food packaging, or pharma lines need matched cavities and bph before quoting compressors, chillers, and line integration — not a generic automatic stretch blow molding machine that misses bottle volume or robust output range targets.
| Model | Cavities | Robust Output Range (BPH) | Max Bottle Volume |
|---|---|---|---|
| BlowPacker-2C | 2 | 2,400–3,000 bottles per hour | 2.0 L |
| BlowPacker-8C | 8 | 11,000–12,000 bph | 0.6 L |
This full automatic pet stretch blow molding machine line automates preform loading through finished bottle manufacturing ejection for US packaging plants. Two-step all-electric architecture separates oven heating from blow molding — distinct from injection stretch blow molding one-step molding process systems used on small-container ISBM lines.

Engineering Infrastructure
As a leading automatic stretch blow molding machine manufacturer, we design our infrastructure around three main pillars:
- Two-Step PET Blow Molding Equipment Design: Separates the preform heating oven process from the actual blowing phase, maximizing thermal efficiency and reducing energy consumption by up to 30%.
- Servo-Driven Stretch System: Guarantees absolute precision during the mechanical stretching process, ensuring uniform wall thickness across every single bottle.
- Heavy-Duty Chassis: Built with structural steel to eliminate vibration, extending the lifespan of your mold components during continuous high-speed operations.
Advanced Engineering Features & Component Architecture
We engineer our automatic pet stretch blow molding machine with a focus on high-speed stability and component synergy. By moving away from legacy pneumatic-heavy setups, we rely on a heavy-duty mechanical frame and premium electronic integration to handle the continuous stress of high-output production.
Smart Preform Feeding & Heating System
Our two-step PET blow molding equipment features an optimized preform heating oven that maximizes energy efficiency. Preforms are fed automatically into a localized mandrel system, flipping upside down to protect the neck finish during heating.
- Infrared Heating Lamps: Individually controlled heating zones allow precise penetration for varied preform wall thicknesses.
- Cooling Channel System: Integrated water cooling protects the preform neck from deformation.
- Continuous Rotation: Ensures uniform heat distribution before entering the cavities.
High-Pressure Mold Clamping Mechanism
To completely eliminate parting-line flash on finished bottles, our fully automatic stretch blow molding machine utilizes a high-pressure toggle clamping system. This mechanism locks the mold halves together with massive force during the high-pressure air injection phase.
- Pneumatic Compensator: Compensates for any micro-movements during the final blow phase.
- Rapid Changeover Design: Standardized slider gates allow teams to swap out mold cavity configurations quickly.
- Durability: Hardened alloy plates minimize wear over millions of cycles.
All-Electric Servo System Integration
This is an all-electric PET blow molding machine built for precision. We have replaced unpredictable pneumatic valves with synchronous servo motors to control the servo-driven stretch system and main transfer components.
| Feature | Servo-Driven System | Traditional Pneumatic System |
|---|---|---|
| Positioning Accuracy | Micro-precise (± 0.1 mm mechanical control) | Variable based on air pressure fluctuations |
| Energy Efficiency | Up to 30% reduction in power consumption | High compressed air energy waste |
| Output Stability | Consistent bottles per hour (BPH) speed | Speed drops under heavy factory loads |
| Maintenance | Minimal wear parts, direct drive | High maintenance on seals and cylinders |
