The medical and pharmaceutical industries demand the highest standards of hygiene, dimensional accuracy, and material integrity. Producing medical vials, IV bottles, and precise dosage containers requires technology that eliminates contamination risks. At Ever Power, our cleanroom-compatible دستگاه قالب گیری بادی کششی تزریقی تک مرحله ای provides the definitive solution. By integrating the entire manufacturing process into one enclosed, highly controlled environment, we help pharmaceutical packagers achieve flawless quality and exceptional production stability.
فناوری ISBM تک مرحلهای چیست؟
One-step injection stretch blow molding (ISBM) is an advanced, highly efficient plastic container forming process. It is specifically designed to produce high-precision hollow plastic products from materials such as PET, PETG, PP, PC, Tritan, and PLA. The most critical feature of this technology is that injection, stretching, and blow molding are all completed continuously within the same equipment. There is no intermediate handling, cooling, or storage of preforms, which drastically reduces the risk of particulate contamination—making it ideal for medical packaging.
جریان فرآیند سادهشده
- ۱. تزریق: Molten resin is injected into a highly precise mold to form the preform, ensuring perfect thread and neck finish dimensions for medical closures.
- ۲. برش دم پریفرم / حفظ حرارت: The latent heat from the injection stage is retained and carefully equalized to prepare the plastic for uniform stretching.
- ۳. قالبگیری بادی کششی: A stretch rod axially extends the preform while sterile, high-pressure air radially expands it into the final medical vial shape.
- ۴. بیرونبر بطری: The finished, defect-free vial is automatically ejected, ready for immediate cleanroom packaging or filling.
Core Advantages for Medical Manufacturing

ترکیب تجهیزات و فناوریهای کلیدی
Our exceptional دستگاه قالب گیری بادی ISBM architecture consists of five major integrated systems. Here is an inside look at the technology ensuring your medical vials meet strict compliance.
۱. سیستم تزریق
The injection system utilizes a high-precision servo-driven unit equipped with a highly specialized barrel. We proudly emphasize our patented injection screw design, which is meticulously engineered to prevent material degradation and ensure highly uniform plastic melt plasticization, a critical factor for achieving crystal-clear pharmaceutical plastics.

- Servo-driven injection unit (delivers fast response times and exceptional repeatability).
- سیستم کنترل ضخامت دیواره پیش فرم (ضخامت را از طریق تنظیمات دقیق محوری یا شعاعی بهینه میکند).
۲. سیستم گرمایش
Utilizing advanced heating rings or a combination of water and oil temperature controls, our system guarantees perfect preform conditioning.
- Zoned heating control (achieves precise temperature regulation across different sections of the preform for complex vial shapes).
- Non-contact temperature measurement (prevents any physical damage or contamination to the preform surface).
- Adaptive heating power (automatically optimizes heating parameters based on the current production speed).
۳. سیستم ضربه کششی
This system performs the crucial biaxial stretching and high-pressure blowing.
- Advanced stretch mechanism (stretching speeds up to 400mm/s with an exact positional accuracy of ±0.1mm).
- Independent high-pressure gas regulating valve system (strictly controls pressure fluctuations within ±0.05MPa to guarantee exact vial volumes).
- فناوری کنترل همزمان کشش و دمش (هماهنگی دقیق مراحل کشش و دمش را تضمین میکند).
۴. سیستم قالب
The mold system typically employs a rotary multi-station structure. For medical manufacturing, we offer configurations that perfectly balance speed and conditioning.
ساختار قالب ۳ ایستگاهی: Integrates Injection, Stretch Blow Molding, and Ejection. It is highly efficient and perfect for standard pharmaceutical pill bottles and standard vials.
ساختار قالب ۴ ایستگاهی: Incorporates an extra temperature conditioning station before blowing. This is vital for complex, thick-walled medical containers requiring precise thermal management.

A Wide Variety of High-Precision Finished Containers Produced by Ever Power ISBM Machines
Crucial Integration: Cleanroom-Grade Blowing Air Compressors
In medical vial manufacturing, the purity of the end product is non-negotiable. This brings us to a critical, yet frequently overlooked component of the ISBM process: the blowing air compressor.
During the stretch blow molding phase, high-pressure compressed air is injected directly into the heated preform to expand it against the mold walls. Because this air makes direct contact with the interior surface of the medical vial, it must be absolutely pristine. Any trace of compressor oil, moisture, or particulate matter will permanently contaminate the container, leading to immediate batch rejection and severe compliance failures.
Furthermore, the volumetric accuracy of pharmaceutical bottles relies entirely on maintaining a perfectly stable blowing pressure. Ever Power provides specially matched, premium کمپرسورهای هوای اسکرو بدون روغن designed specifically for our blow molding machines. These integrated compressors guarantee a 100% oil-free, dry, and consistently stable high-pressure air supply. By utilizing our matched compressor systems, pharmaceutical manufacturers ensure flawless, sterile production runs, uniform wall thicknesses, and strict adherence to cleanroom standards, thereby safeguarding their products and maximizing operational ROI.

سوالات متداول (FAQ)
1. What is the cycle time for a standard 100ml PET medical vial?
Cycle times typically range from 15 to 25 seconds, depending heavily on the vial’s wall thickness and the specific number of mold cavities used in the setup. Our highly optimized cooling systems ensure these rapid speeds are maintained consistently.
2. How does the machine aid in cleanroom standard compliance?
By performing injection and stretch blow molding sequentially within a single enclosed unit, the heated plastic is never exposed to the outside environment, eliminating intermediate transport contamination. Paired with our recommended oil-free air compressors, it ensures sterile internal bottle surfaces.
3. Can we produce high-temperature sterilizable IV bottles on this machine?
Yes, our machines are perfectly capable of processing Polypropylene (PP), which can withstand temperatures above 120℃. This makes the equipment highly suitable for IV fluid bottles that require hot-filling or post-fill autoclave sterilization.
4. How complicated is the mold changeover process for different vial sizes?
We have engineered the machine with rapid mold changeover technology. An experienced operating team can typically swap out both the injection preform mold and the blow mold and have the machine ready to run the new design in under 60 minutes.
5. How do you ensure the volumetric accuracy of liquid medication bottles?
Volumetric accuracy depends on exact material distribution. Our patented injection screw ensures perfectly uniform plastic melt, while our multi-axis control system and independent high-pressure gas valves maintain absolute precision during the stretching and blowing phases, ensuring every bottle matches the exact mold volume.
