Introduktion till enstegs formsprutning med sträckblåsning
En enstegs formsprutningssträckformningsmaskin utilizes a highly advanced, integrated plastic container forming process. This technology is universally recognized as the safest and most reliable method for manufacturing high-precision, strictly regulated hollow plastic products. While versatile enough for luxury cosmetics and pharmaceutical packaging, it is the absolute global standard for producing infant care items, specifically baby feeding bottles. Our equipment effortlessly processes a wide variety of medical-grade and food-safe materials, including PET, PETG, PP, PC, Tritan, PPSU, PS, ABS, and PLA.

The defining feature of this technology is continuous integration. The three critical stages—injection, stretching, and blow molding—are executed sequentially within the exact same enclosed equipment. By completely eliminating intermediate handling, cooling, and storage, this process drastically reduces the risk of biological contamination, ensuring absolute product stability, hygiene, and the immense durability required for baby products.

Utrustningskomposition och nyckelteknologier
Processing high-temperature, highly viscous engineering plastics requires our machinery to be constructed from five heavily reinforced, precision subsystems: Injection, Heating, Stretch Blow, Mold, and Control systems.
1. Injektionssystem
This system utilizes a high-precision servo-driven injection unit. For materials like Tritan and PPSU, a dedicated barrel ensures flawlessly uniform melt plasticization without degrading the polymer.

- Stretch-blow synchronous control technology (guarantees perfect coordination during the intense expansion phase).
4. Formsystem
Formsystemet innehåller preformformen, blåsformen och specialiserade kylkanaler. Vi använder en högeffektiv roterande flerstationsstruktur, tillgänglig i 3 eller 4 stationer beroende på dina specifika flaskdesignkrav.
3-stations formuppsättning
Integrates Injection, Stretch Blow, and Ejection. Optimal for standard high-speed production.

4-stations formuppsättning
Includes a dedicated Temperature Conditioning station. Absolutely essential for PPSU and Tritan baby bottles to prevent stress whitening and ensure perfectly uniform wall thickness.

- PPSU (Polyphenylsulfone): The absolute highest standard for medical containers and top-tier baby bottles. It boasts a distinct golden honey color, massive structural strength, and can withstand over 1,000 extreme steam sterilization cycles.
- Polypropen (PP): The standard, cost-effective choice for reliable baby bottles requiring hot-fill capabilities or frequent boiling water sterilization (120℃+).
- Polykarbonat (PC): Utilized for specific premium products and medical devices, boasting massive structural strength.
Genom att utnyttja dessa maskiner kan fabriker sömlöst tillverka:
- Premium baby feeding bottles and sippy cups.
- High-end, reusable sports water bottles.
- Specialized medical packaging (transparent IV bottles, eye droppers).
- Thick-walled cosmetic containers (nail polish remover bottles, perfume containers).

The Crucial Role of Oil-Free Air Compressors in Infant Care Production
When configuring a high-precision production line for baby feeding 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 bottle. Because this air makes direct contact with the interior walls of the container, its purity cannot be compromised.
Infant care products are subject to the most stringent hygienic and purity standards globally. Standard factory compressors frequently leak microscopic mechanical oil vapors and moisture into the airflow. If this contaminated air enters the bottle, it poses a severe health risk to infants and will result in failed safety audits. We provide specialized Oljefria skruvluftkompressorer 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 safety of your baby bottles, eliminate compliance risks entirely, and greatly extend the lifespan of your machine’s pneumatic components.

Vanliga frågor (FAQ)
1. Why is the 1-step process superior for manufacturing baby 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 severe 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, guaranteeing the absolute sterility required for baby products.
2. How does the machine handle high-temperature plastics like PPSU?
Our machines utilize a highly specialized, patented injection screw and heavy-duty servo motors specifically designed to generate the high torque and precise melt plasticization required for thick, viscous resins like PPSU and Tritan without burning or degrading the material.
3. Why is the 4-station mold recommended for baby bottles?
Baby bottles, particularly those made from Tritan or PPSU, often have thick bases or ergonomic grips. The 4-station system includes an extra temperature conditioning step that perfectly equalizes the heat between thick and thin areas of the preform before stretching. This prevents stress whitening and ensures uniform wall thickness for maximum durability against drops.
4. Can this equipment guarantee the tight thread tolerances needed for anti-colic nipples?
Absolutely. The injection phase of our ISBM machine forms the neck and threads of the bottle with pinpoint accuracy inside a solid steel mold, completely independently of the blowing phase. This ensures every bottle has identical, rigid threading perfectly suited for complex, leak-proof baby bottle collars.
5. Varför är en oljefri luftkompressor absolut nödvändig?
The compressed air touches the interior of the baby bottle to form it. If you use a standard compressor, trace amounts of lubricating oil and moisture will contaminate the inside of the bottle, violating FDA and global infant safety standards. An oil-free screw compressor ensures 100% pure, safe air.
