- Adaptive heating power: Automatically optimizes parameters based on production speed.
3. Sistema de soplado de estiramiento
Comprising stretch rods, blow cores, and high-pressure air sources to achieve exact axial stretching and radial expansion.
- Stretching mechanism: Speeds up to 400mm/s with a position accuracy of ±0.1mm.
- Independent pressure regulation: High-pressure gas fluctuation controlled within ±0.05MPa.
- Stretch-Blow synchronization: Ensures precise coordination for flawless bottle shaping.
4. Mold System (3-Station vs. 4-Station)
The mold system includes preform molds, blow molds, and cooling channels, typically configured in a rotary multi-station structure. We offer both 3-station and 4-station configurations depending on your specific product geometry and material needs.
Configuración de 3 estaciones
(Injection → Stretch Blow → Ejection). Best for high-efficiency production of standard round or cylindrical bottles, reducing cycle time and footprint.
Configuración de 4 estaciones

El papel fundamental de los compresores de aire de tornillo sin aceite
Why is an Oil-Free Screw Air Compressor essential for an ISBM machine? The stretch blow molding process requires high-pressure, exceptionally clean compressed air to expand the preform into its final shape. Any trace of oil or moisture in the air supply can cause severe defects, such as cloudiness, uneven material distribution, or contamination inside the container—which is strictly prohibited in food, beverage, and pharmaceutical packaging.
We provide matching, dedicated oil-free screw air compressors that guarantee 100% pure air delivery at stable high pressures. They are engineered to handle the rigorous demands of a continuous Máquina de moldeo por soplado de PET de un solo paso. By stabilizing the blow pressure, they prevent pneumatic valve clogging, extend component lifespans, and ensure consistent volume across every cavity, lowering your reject rates and optimizing energy use.

Compared to traditional two-step machines that require reheating cold preforms, our one-step process saves about 40% in energy. Furthermore, the integration of advanced dual servo-motors and nano-far-infrared heating rings ensures optimal electrical efficiency during every cycle.
3. Can one machine produce bottles from both PET and high-temperature materials like PC or PPSU?
Absolutely. With our specialized patented screw design and precise zoned heating controls, the machine is highly adaptable. By simply adjusting the parameters and swapping molds, you can switch from producing standard PET water bottles to high-temperature PC or PPSU baby bottles.
4. What happens if a part breaks? Are spare parts easy to find overseas?
We intentionally use globally recognized, top-tier components (such as Yaskawa servos, Parker valves, and Yuken hydraulics). This ensures it operates as a Máquina de moldeo por soplado de un solo paso con bajos costos de mantenimiento.. You can easily source replacement standard parts from local distributors in your country, minimizing downtime. We also ship proprietary parts globally via express freight.
5. What is the standard lead time if we order a machine and custom molds today?
The typical production lead time for a standard ISBM blow molding machine is 45-60 days. If you require custom molds, mold design and rigorous pre-shipment testing (dry-run and material trials) will add approximately 15-20 days to ensure the equipment is plug-and-play ready upon arrival at your factory.
