Giới thiệu về ép phun kéo giãn thổi khuôn một bước
A máy ép phun kéo giãn thổi một giai đoạn utilizes a highly advanced, integrated plastic container forming process. This technology is the industry standard for manufacturing high-precision, visually demanding, and strictly regulated hollow plastic products. It is the ideal technology for baby feeding bottles, water cups, delicate crafts, high-end cosmetic containers, and crucially, pharmaceutical packaging like sterile eye drop bottles. Our equipment effortlessly processes a wide variety of materials, including PET, PETG, PP, PC, Tritan, PS, ABS, and PLA.

Ứng dụng vật liệu và khả năng sản phẩm
Our one step PET blow molding line with automation processes a broad range of thermoplastics effortlessly:
- Polyethylene Terephthalate (PET): Widely applied for beverages and chemical solvents, known for high transparency, strong barrier resistance, and recyclability.
- Polypropylene (PP): The absolute standard for eye drop bottles and hot-fill containers. It is highly squeezable, sterilizable, and possesses excellent chemical resistance.
- Polyethylene Terephthalate Glycol (PETG): A premium material for high-end cosmetics. It features glass-like clarity, high viscosity, incredible chemical resistance, and powerful anti-stress whitening capabilities.
- Polycarbonate (PC): Utilized for premium baby bottles and sports cups, boasting massive structural strength and heat resistance.
Leveraging this machinery, factories can seamlessly manufacture:
- Round or complex contoured beverage bottles (capacities 5ml to 20L).
- Pharmaceutical packaging (eye drop bottles, pill bottles, oral liquid vials).
- Food packaging containers (edible oil jugs, condiment jars).
- Daily chemical and premium cosmetic packaging (nail polish remover bottles, perfume containers).
The Crucial Role of Oil-Free Air Compressors in Pharmaceutical Production
When configuring a high-precision production line for medical-grade eye drop bottles, the quality of your auxiliary equipment dictates the safety of the final product. A high-performance air compressor is absolutely critical. During the stretch blow phase, high-pressure air forcefully expands the melted plastic against the mold cavity to form the eye drop bottle. Because this air touches the interior walls of the container, its purity cannot be compromised.
Pharmaceutical products have the most stringent hygienic and purity standards globally. Standard factory compressors frequently leak microscopic oil vapors and moisture into the airflow. If this contaminated air enters the bottle, it will ruin the sterile environment and contaminate the medical solution when filled. We provide specialized Máy nén khí trục vít không dầu explicitly matched to our blowing machinery. These units guarantee a continuous stream of 100% pure, dry, oil-free high-pressure air. By choosing our integrated compressor solution, you ensure the absolute sterility of your eye drop bottles, eliminate compliance risks entirely, and greatly extend the lifespan of your machine’s pneumatic components.

Câu hỏi thường gặp (FAQ)
1. Why is the 1-step process superior to the 2-step process for pharmaceutical bottles?
In a 2-step process, preforms are created, ejected into a bin, stored, and transported to a separate blowing machine later. Every transfer point introduces a risk of dust, human touch, or bacterial contamination. The 1-step process creates the bottle continuously in an enclosed space from molten plastic to finished container, making it inherently more sterile.
2. What material is typically used for squeezable eye drop bottles?
PP (Polypropylene) or highly specialized, soft-grade PET materials are most commonly used. They provide the necessary flexibility for the consumer to squeeze drops out accurately, while maintaining excellent chemical resistance and sterilizability.
3. Can this equipment guarantee the tight thread tolerances needed for dropper caps?
Absolutely. The injection phase of our ISBM machine forms the neck and threads of the bottle with pinpoint accuracy, completely independently of the blowing phase. This ensures that every bottle has identical, leak-proof threading perfect for medical dropper caps.
4. Is this machine suitable for cleanroom environments?
Yes. Our machines are designed with a compact footprint, enclosed operating areas, and run on precise, clean electrical servos rather than entirely on messy hydraulics. They are routinely installed in cleanroom environments worldwide.
5. Why is an oil-free air compressor strictly necessary?
The compressed air touches the interior of the eye drop bottle to form it. If you use a standard compressor, trace amounts of oil and moisture will contaminate the inside of the bottle, violating medical safety standards. An oil-free screw compressor ensures 100% pure air.
