The production of diagnostic reagent sample bottles demands the highest level of precision in the packaging industry. These containers must possess perfect optical clarity, absolute dimensional stability to prevent leaks, and a zero-contamination environment. At Ever Power, our advanced เครื่องเป่าขึ้นรูปพลาสติกแบบบูรณาการ technology provides a seamless, highly automated solution. By combining the entire forming process into a single, enclosed cycle, we eliminate intermediate handling risks and deliver the perfect platform for medical and diagnostic manufacturing.
What is One-Step ISBM Technology?
One-step injection stretch blow molding (ISBM) is a highly efficient plastic container forming process. It is widely applied in producing high-precision, high-demand hollow plastic products from materials such as PET, PETG, PP, PC, Tritan, PS, ABS, and PLA. The core defining characteristic is that the three primary steps—Injection, Stretching, and Blow Molding—are completed continuously within the exact same equipment. This eliminates intermediate preform storage and reheating, dramatically increasing production efficiency and ensuring unmatched product stability.
กระบวนการทำงานที่คล่องตัว
High-precision injection of molten resin into the cavity forms the preform, defining exact neck dimensions for leak-proof reagent caps.
The preform’s tail is cut, and latent heat is perfectly equalized across the body to ensure uniform stretching conditions.
The preform is axially stretched and radially blown, orienting molecules to maximize barrier properties and optical clarity.
The finished, sterile diagnostic bottle is automatically ejected and ready for immediate automated filling lines.
Core Advantages for Diagnostic Production
- High Efficiency & Energy Saving: By avoiding secondary reheating of the preform and directly utilizing the injection temperature, energy consumption is reduced by approximately 40%.
- Superior Performance: Biaxial stretching significantly enhances the bottle’s compressive resistance, gas/moisture barriers, and transparency—vital for visual diagnostic checks.
- High Precision & Stability: Full-process automated control eliminates human error, guaranteeing the tight tolerances required for medical packaging.
- Optimal ROI: Enjoy high material utilization (minimal scrap), a compact footprint, low labor requirements, and highly competitive equipment pricing.

Inside the Technology: Equipment Composition
Our machine’s reliability stems from five meticulously engineered core systems.
1. ระบบฉีด
Utilizing a high-precision servo-driven injection unit, this system guarantees uniform plastic melt. We strictly utilize our patented injection screw and barrel design, specially created to manage the melting profile of medical-grade plastics without causing degradation or bubbles.
Our Patented Injection Screw Design

- Servo-driven injection unit (rapid response, exceptional repeat accuracy).
- Preform wall thickness control system (optimizes thickness via axial or radial adjustments).
2. ระบบทำความร้อน
The system conditions the preform using advanced heating rings or water/oil temperature configurations.
- Zoned heating control (precise temperature regulation across different preform zones).
- Non-contact temperature measurement (avoids any surface damage).
- Adaptive heating power (automatically optimizes parameters based on production speed).
3. ระบบการเป่าขึ้นรูปยืด (Stretch Blow System)
- Advanced stretch mechanism (stretching speed up to 400mm/s, positional accuracy ±0.1mm).

Crucial Integration: Matched Oil-Free Air Compressors
When producing diagnostic reagent sample bottles, absolute purity and precise dimensional control are non-negotiable requirements. This makes the blow molding air compressor an indispensable component of the entire manufacturing line.
In the one-step injection stretch blow molding process, high-pressure compressed air is injected directly into the preform to expand it against the mold cavity. If standard compressors are used, microscopic oil particles, moisture, or dust can contaminate the interior of the sample bottle. For diagnostic reagents, even trace amounts of contamination can cause false test results or spoil the sensitive chemicals stored inside.
Furthermore, creating perfectly uniform wall thicknesses and exact neck finishes relies on absolute pressure stability. Pressure fluctuations will cause dimensional inaccuracies, leading to leaking caps. Ever Power solves this by providing specialized, perfectly matched oil-free screw air compressors. These systems guarantee a 100% clean, dry, and highly stable high-pressure air supply. By integrating our matching compressors with your ISBM equipment, you ensure medical-grade hygiene, eliminate rejection rates due to contamination, and maintain the precise volumetric accuracy required for critical diagnostic applications.

คำถามที่พบบ่อย (FAQ)
1. What is the average cycle time for a small 10ml to 50ml diagnostic sample bottle?
For smaller sample bottles, cycle times are exceptionally fast, generally ranging from 12 to 18 seconds, depending on the specific resin and the number of mold cavities used.
2. Can the machine run PP (Polypropylene) for autoclavable reagent bottles?
Yes, the machine easily processes PP. Our patented injection screw and precise temperature controls ensure uniform melting, allowing you to produce bottles that can withstand sterilization temperatures over 120℃.
3. How does the machine ensure wall thickness consistency?
Wall thickness is managed through our advanced preform wall thickness control system, which allows precise axial and radial adjustments during the injection phase, combined with strictly controlled high-pressure air during blowing.
4. How long does a mold changeover take?
Our systems are equipped with rapid mold change technology. A trained operational team can completely swap out the molds and transition to a new bottle design in 60 minutes or less.
5. Does this process require an external preform heating oven?
No. This is the primary advantage of the one-step process. It directly utilizes the residual heat from the injection stage to condition the preform for blowing, eliminating the need for an external oven and saving approximately 40% in energy costs.
