1. Descripción general del producto
Sectores aplicables: Large-scale mineral water, carbonated soft drinks (CSD), daily chemicals, and pharmaceutical packaging.
Resumen de las principales ventajas: Understanding the mechanics of your machinery is the first step toward optimizing your factory’s output. EVER POWER, a leading manufacturer headquartered in the Netherlands, engineers two-stage stretch blow molding machines that completely decouple preform injection from the blowing phase. This architecture unlocks blazing fast production speeds, unparalleled material distribution, and the ability to lightweight containers without sacrificing top-load strength.

3. Working Principle & Internal Workflow
The term “two-stage” means the creation of the bottle happens in two entirely separate locations. First, raw PET resin is injection-molded into a test-tube-like shape called a preform (Stage 1). The magic happens in the blow molding machine (Stage 2). The cold preforms are loaded into a hopper and automatically sorted onto internal mandrels. They travel through an infrared heating tunnel, rotating continuously to ensure the polymer softens evenly. Once heated to its precise elastic state, robotic grippers move the preform into the aluminum mold. A stretch rod pushes the preform down axially, while high-pressure air is injected to expand it radially against the chilled mold walls, setting the plastic instantly.
4. Top 5 Operational Advantages
⚡ Extreme Cycle Speeds
By not waiting for thick plastic to melt and cool inside an injection mold, the machine can process up to 9200 bottles per hour continuously.
🧊 Chilled Aluminum Tooling
Our custom aluminum blowing molds extract heat out of the PET matrix instantly, drastically reducing the required cooling dwell time.
🎯 Precise Thread Protection
Because the neck is pre-injected and shielded during the heating phase, capping tolerances remain 100% accurate, eliminating downstream leaks.
📦 Supply Chain Independence
You can purchase standard preforms globally in massive, compact bulk quantities, rather than storing massive silos of raw resin.
♻️ Exhaust Air Recycling
Our advanced manifolds capture the 35-bar exhaust blast and reroute it to power the machine’s low-pressure mechanical movements.
5. Estructura y tecnología de materiales
A machine operating at these speeds requires immense rigidity. EVER POWER chassis are forged from heavy-duty alloy steel to absorb harmonic vibrations. The clamping toggles utilize thickened pins to resist the cyclic outward pressure of the 35-bar blow. Inside the heating oven, ceramic-backed reflectors ensure that 95% of the infrared light generated is directed into the preform wall, rather than escaping into the factory environment.
6. Aplicaciones típicas
High-Speed Water Bottling
Connecting the blow molder directly to the filling carousel to execute continuous liquid packaging with ultra-light preforms.
Daily Chemical Packaging
Using servo-controls to push PET material cleanly into the sharp, asymmetrical corners of thick lotion bottles.
7. Guía de selección
When selecting your layout, ensure you calculate your air compressor needs correctly. The blowing phase requires high-pressure (3.0 MPa), whereas the mechanical movements require low-pressure (0.8 MPa). EVER POWER simplifies this by offering turnkey compressor and chiller packages matched exactly to your machine’s cavity count and BPH demands.

10. Estudios de caso: Notas de campo globales
11. Preguntas frecuentes
What does biaxial stretching mean?
It refers to stretching the PET polymer chains in two directions simultaneously: vertically via the mechanical stretch rod, and horizontally via the high-pressure air. This provides immense structural strength.
Why use aluminum instead of steel for molds?
Aluminum dissipates heat much faster than steel. Rapid cooling sets the plastic instantly, drastically shortening the machine’s cycle time and increasing your hourly yield.
