Ensuring absolute hygiene, precision, and efficiency in medical container manufacturing.
Introduction to ISBM Technology & Core Advantages
One-step Injection Stretch Blow Moulding (ISBM) is an advanced, highly efficient plastic container molding process. It is exceptionally suited for high-precision, high-demand hollow plastic products. A premium eentraps spuitgiet-rekblaasvormmachine seamlessly processes materials like PET, PETG, PP, PC, Tritan, PS, ABS, and PLA to produce flawless baby bottles, water bottles, cosmetic packaging, and critically, pharmaceutical vials.
The primary characteristic of an geïntegreerde blaasvormmachine is that the three core stages—injection of the preform, stretching, and blowing—are completed continuously within a single enclosed system. There is no intermediate handling, storing, or reheating of preforms. This continuous flow prevents human contamination, significantly boosts production efficiency, and guarantees impeccable product stability.

- Hoge precisie en stabiliteit: Fully automated closed-loop controls eliminate human errors. For pharmaceuticals, this ensures exact neck finishes for leak-proof sealing.
- High Energy Efficiency: The process blows the bottle using the preform’s initial injection heat, skipping secondary reheating ovens and lowering energy consumption by roughly 40%.
- Superior Barrier Properties: Biaxial stretching optimally aligns material molecules, greatly enhancing the container’s resistance to pressure and gas permeation.
- Excellent Equipment Economics: Low energy requirements, minimal manual labor, zero-flash material utilization, and a compact footprint yield highly competitive operational costs.

Why Oil-Free Air Compressors Are Mandatory for Pharma
For pharmaceutical packaging, hygiene and precision are non-negotiable. This is exactly why an Oil-Free Screw Air Compressor is a mandatory component when operating a high-speed éénstaps flessenblaasapparatuur. During the stretch blow molding phase, high-pressure compressed air is injected directly into the hot preform to shape the final bottle. If a standard lubricated air compressor is used, microscopic oil particles, moisture, and contaminants can mix with the blowing air and adhere to the inner walls of the medical bottles. This instantly compromises the sterility of the packaging.
To prevent this, Ever Power provides specialized, 100% oil-free screw air compressors perfectly matched to our ISBM blaasvormmachine lineup. These compressors guarantee a continuous supply of pure, dry, and highly stable high-pressure air. Beyond ensuring absolute medical-grade cleanliness, a stable air supply protects the sensitive pneumatic valves inside the blow molding equipment from oil-sludge build-up. This significantly reduces maintenance downtime, extends the lifespan of your machine, and ensures that every pharmaceutical PET bottle maintains perfect structural integrity, uniform wall thickness, and flawless glass-like transparency.

Veelgestelde vragen
1. Why is single-stage blow molding superior to two-stage for pharmaceutical bottles?
In a single-stage process, the preform is blown immediately after injection without ever leaving the enclosed machine environment. This eliminates the need for storage, transportation, and reheating, thereby preventing surface scratches and entirely eliminating human contamination risks—critical for medical standards.
2. Can this machine operate effectively inside a medical cleanroom?
Yes. Our machines are designed with enclosed architectures, servo-driven (oil-free) major movements, and automated take-out systems. When paired with an oil-free air compressor, the system generates minimal particulate emissions, making it highly suitable for cleanroom environments.
3. Zijn uw machines compatibel met ASB-matrijzen?
Absolutely. For example, our EPY250-V4 is fully structurally compatible with standard ASB-70DPH molds, and the EPY150-V4 works perfectly with ASB-12M molds. You can seamlessly utilize your existing tooling to upgrade production.
4. What is the production capacity for a standard 100ml PET syrup bottle?
Production speed depends on the specific bottle design and cavitation of the mold. A typical multi-cavity setup on our 3-station machine can reliably produce thousands of high-precision 100ml bottles per hour, ensuring a highly profitable output rate.
5. How does the equipment ensure uniform wall thickness in every bottle?
We achieve this through our patented screw design which ensures uniform melt, combined with a precise zoned heating control system. Additionally, the servo-driven stretch rod and synchronized high-pressure air expansion guarantee perfectly even material distribution across the entire container wall.
