The production of high-quality, safe infant feeding bottles has seen a massive shift towards advanced materials like Polyphenylsulfone (PPSU). Known for its incredible heat resistance, durability, and BPA-free safety, PPSU is the gold standard. However, processing this material requires absolute precision. This is where the เครื่องเป่าขึ้นรูปขวดนมแบบขั้นตอนเดียวที่ดีที่สุด comes into play.
One-step Injection Stretch Blow Molding (ISBM) is a highly efficient manufacturing process. Its core feature is that the three primary steps—injection of the preform, stretching, and blow molding—are completed sequentially within a single piece of equipment. This eliminates intermediate steps like preform cooling and reheating, significantly boosting production efficiency and ensuring the flawless consistency required for premium PPSU baby bottles.
The 4-Station Process Flow & Advantages
- 1. การฉีด: Molten plastic is injected to form a highly accurate preform.
- 2. Preform Thermal Conditioning: Crucial for PPSU, the preform temperature is optimized for stretching.
- 3. การขึ้นรูปด้วยการเป่าแบบยืด (Stretch Blow Moulding): The preform is stretched axially and blown radially.
- 4. บริการซื้อกลับบ้านแบบขวด: The finished PPSU bottle is ejected automatically.
The advantages of this integrated approach are profound:
- ประสิทธิภาพการใช้พลังงาน: By utilizing the residual heat from injection, energy consumption is reduced by approximately 40%.
- ประสิทธิภาพที่เหนือกว่า: Biaxial stretching enhances the PPSU material’s inherent strength, impact resistance, and clarity.
- ความแม่นยำสูง: Fully automated control minimizes human error, ensuring the critical neck dimensions for baby bottles are perfectly consistent.
- การใช้ประโยชน์จากวัสดุอย่างมีประสิทธิภาพสูง: The process generates minimal waste, which is vital given the high cost of raw PPSU resin.

Five Core Systems for Flawless Production
1. ระบบฉีดขึ้นรูปความแม่นยำสูง
Processing PPSU requires exceptional melt uniformity. Our servo-driven injection unit utilizes a การออกแบบสกรูที่ได้รับการจดสิทธิบัตร specifically optimized for high-temperature resins.
- การควบคุมอุณหภูมิที่มีความแม่นยำสูง (±1℃)
- Rapid response servo-driven injection.
- Advanced preform wall thickness control.
2. ระบบทำความร้อนแบบปรับได้
Features zoned heating control for precise temperature profiles across the preform. Non-contact measurement prevents surface damage, and power adapts automatically to production speeds.
3. ระบบเป่าขึ้นรูปยืดแบบซิงโครไนซ์
Achieves stretching speeds up to 400mm/s (±0.1mm accuracy). High-pressure gas is managed by independent valves, keeping fluctuations tightly controlled within ±0.05MPa for perfect forming.
4. ระบบแม่พิมพ์แบบหลายสถานี
For high-end materials like PPSU or heavy-walled cosmetics, the 4-station mold structure is essential. The dedicated conditioning station ensures the preform is thermally perfect before stretching.
Standard 3-Station Layout
Advanced 4-Station Layout (Ideal for PPSU)
Our molds feature a cavity surface roughness of Ra≤0.8μm. Efficient cooling channels cut cycle times by 30%. Proper wiring for these advanced molds is critical:
Ever Power also designs and manufactures custom molds for your specific needs.
5. Smart Control System
A multi-axis motion control system guarantees precise synchronization. It includes adaptive process optimization and remote diagnostic tools to ensure maximum uptime.
Beyond PPSU: Versatile Material Applications
While dominating the baby bottle sector, our สายการผลิตขึ้นรูปพลาสติก PET แบบเป่าขึ้นรูปขั้นตอนเดียวพร้อมระบบอัตโนมัติ is incredibly versatile, handling materials like:
- สัตว์เลี้ยง: High transparency for beverage and food jars.
- พีพี: Heat resistant (>120℃) for hot-fill juices.
- PETG: High toughness and clarity, perfect for thick-walled cosmetic jars without stress whitening.
- พีซี: Excellent impact and heat resistance.
Crucial Equipment: The Matched Oil-Free Air Compressor
For a one-step machine to successfully form complex shapes like baby bottles, a highly stable, high-pressure air source is mandatory. If the blowing pressure fluctuates even slightly, the bottle will suffer from uneven wall thickness or poor dimensional tolerances.
Furthermore, because baby bottles demand the highest safety standards, the blowing air must be absolutely free of oil vapor to prevent contamination. Ever Power provides specially engineered, matched oil-free screw air compressors. These guarantee a clean, perfectly stable air supply, ensuring your ISBM machine operates flawlessly and your final products meet strict hygienic standards.

คำถามที่พบบ่อย
1. Why is the one-step process better for PPSU baby bottles?
PPSU is an expensive, high-temperature resin. The one-step process minimizes material waste and provides exceptional temperature control from injection to blowing. This continuous heat history prevents the material degradation and stress issues often seen in two-step processing.
2. Can your machines accommodate legacy Japanese molds?
Yes. Many of our machines are structurally designed with platen dimensions and tie-bar clearances that accept widely used Japanese ASB and Aoki molds, allowing you to upgrade your machine without abandoning your tooling investments.
3. Do I need a 3-station or 4-station machine for baby bottles?
For advanced materials like PPSU or PC used in baby bottles, we highly recommend the 4-station configuration. The dedicated thermal conditioning station ensures the preform has the perfect temperature profile before stretching, which is critical for clarity and impact resistance.
4. How does the machine achieve 40% energy savings?
The savings come from two main areas: utilizing high-efficiency servo-electric drives instead of continuous hydraulic pumps, and bypassing the energy-intensive preform reheating ovens required in traditional two-step blow molding.
5. Is the oil-free compressor absolutely necessary?
For baby bottles, absolutely. Any trace of oil vapor from standard compressors will contaminate the inside of the bottle, violating severe health and safety regulations. Oil-free compressors guarantee a safe, hygienic manufacturing process.
