The demand for pocket-sized cleaning bottles and portable hygiene products has skyrocketed. To meet this need efficiently, manufacturers require equipment that delivers high precision, crystal-clear transparency, and flawless structural integrity. Our advanced máy ép phun kéo giãn thổi một giai đoạn technology is specifically engineered to handle the rigorous demands of producing premium hollow plastic containers from materials like PET, PETG, PP, PC, Tritan, and PLA.
One-Step Injection Stretch Blow Molding (ISBM) is a highly efficient process where injection molding, stretching, and blow molding are completed continuously within a single unit. By eliminating intermediate steps, this technology dramatically improves production efficiency and product stability, making it the perfect choice for high-volume cosmetic, pharmaceutical, and cleaning bottle manufacturing.
The 4-Stage Process Flow
- 1. Injection: Precise molding of the preform.
- 2. Conditioning: Preform tail cutting or heat preservation.
- 3. Stretch Blow Moulding: Biaxial stretching and blowing.
- 4. Bottle Take-out: Automated extraction of the finished product.
Core Advantages
- High Efficiency & Energy Saving: Bypasses secondary preform reheating. Utilizes the latent heat from the injection stage to blow the bottle, slashing energy consumption by approximately 40%.
- Superior Performance: Biaxial stretching aligns material molecules, significantly boosting the container’s pressure resistance, barrier properties, and optical transparency.
- Precision & Stability: Fully automated workflow reduces human error, ensuring dimensionally stable products suitable for rapid, automated filling lines.
- High Material Utilization: Generates minimal waste scrap, ensuring eco-friendly and cost-effective production.
- Ideal Form Factor: As a compact one step injection blow molding machine for small factories, it features low energy consumption, minimal labor requirements, a small footprint, and highly competitive pricing.

Material Application & Finished Products
The flexibility of our technology allows for processing a wide array of thermoplastics:
- PET: High transparency, excellent barrier properties; ideal for food and beverage.
- PP: Withstands temperatures >120℃; great for hot-fill juices and teas.
- PETG: Exceptional for daily chemicals, cleaning sprays, and cosmetics. Offers high viscosity, brilliant transparency, excellent chemical resistance, and anti-stress whitening.
- PC: High strength and heat resistance; standard for baby bottles and sports cups.
From 5ml pocket-sized cleaning sprays to 20L containers, our machines effortlessly produce diverse shapes. This includes customized pharmaceutical bottles, cosmetic packaging, and everyday household items.
The Crucial Role of Our Matching Air Compressors
To achieve the flawless clarity and structural integrity required for premium pocket-sized cleaning bottles, a standard air supply is not enough. Ever Power provides specifically matched Máy nén khí trục vít không dầu to pair with our blow molding machines.
During the stretch-blow phase, high-pressure air directly interacts with the heated internal surface of the plastic preform. If the compressed air contains moisture, oil vapors, or particulate matter, it will instantly cloud the PET/PETG material, leaving oil streaks or sanitary defects inside the bottle. Our matching air compressors deliver 100% oil-free, dry, and highly stable high-pressure air. This steady pressure (controlled within ±0.05MPa) is the secret to ensuring that every pocket-sized spray bottle maintains uniform wall thickness and a premium, glass-like finish.

Frequently Asked Questions
1. What materials are best for pocket-sized cleaning bottles?
PET and PETG are the most highly recommended. PETG, in particular, offers brilliant transparency, high impact resistance, and excellent chemical resistance against the cleaning agents and alcohol often used in these formulas.
2. Can this compact machine operate continuously on an automated line?
Yes. Our machines are designed with full-process automation. They integrate seamlessly with downstream automated taking-out systems, conveyors, and filling lines, making them ideal for stable 24/7 production.
3. How long does it take to change molds if I want to produce a different bottle size?
Thanks to our fast mold changeover technology, a skilled operator can safely change the injection and blow molds in 60 minutes or less, minimizing your production downtime.
4. Do I need to purchase a separate injection molding machine for the preforms?
No. The defining feature of our one-step machine is that the injection of the preform and the final stretch blow molding happen in the exact same unit. This saves you significant floor space and machinery costs.
5. Is this machine suitable for a factory with limited floor space?
Absolutely. Compared to traditional two-stage systems that require separate injection machines, preform storage, and reheating ovens, our integrated system offers a highly compact footprint perfect for smaller factory layouts.
