Upgrading your production line means balancing ultimate precision with cost-efficiency. Explore how our advanced single stage injection stretch blow molding machine delivers world-class stability while drastically reducing your capital and operational expenditures.
Understanding One-Step Injection Stretch Blow Molding (ISBM)
The one-step injection stretch blow molding process is a highly efficient manufacturing technology designed for high-precision, demanding hollow plastic products. This integrated methodology is widely utilized to manufacture baby feeding bottles, water cups, pharmaceutical containers, and premium cosmetic jars using materials such as PET, PETG, PP, PC, Tritan, PS, ABS, and PLA.
The core defining feature of an เครื่องฉีดขึ้นรูปและเป่าขึ้นรูป is that injection, stretching, and blow molding are seamlessly completed in continuous sequence within the exact same equipment. This eliminates intermediate handling, preform storage, and secondary reheating—drastically boosting production efficiency and ensuring flawless product consistency.

องค์ประกอบของอุปกรณ์และเทคโนโลยีหลัก
The EPY200-V4 is engineered around five critical systems, each optimized to outperform traditional standards.
1. ระบบฉีดขึ้นรูปความแม่นยำสูง
The injection system relies on a high-precision servo-driven unit. To ensure absolute uniformity of the plastic melt, we utilize a highly specialized, การออกแบบสกรูและกระบอกที่ได้รับการจดสิทธิบัตร.
Our patented screw design guarantees rapid, homogeneous plasticization.
- ระบบควบคุมอุณหภูมิความแม่นยำสูง (รักษาความแม่นยำไว้ที่ ±1℃)
- Servo-driven injection unit offering lightning-fast response times and high repeatability.
- Advanced preform wall thickness control system for axial/radial optimization.
2. ระบบทำความร้อนแบบปรับได้
The heating system utilizes zoned control via heating rings, water, or oil temperature methods. Crucial technologies include non-contact temperature measurement (protecting the preform surface) and adaptive heating power adjustments that optimize thermal parameters automatically based on live production speeds.
3. ระบบเป่าขึ้นรูปยืดแบบซิงโครไนซ์
Consisting of stretch rods, blow cores, and a high-pressure air source, this system achieves stretching speeds up to 400mm/s with a strict position accuracy of ±0.1mm. High-pressure gas is managed by independent pressure regulating valves, keeping fluctuations tight (±0.05MPa) to ensure perfect stretch-blow synchronization.
4. ระบบแม่พิมพ์แบบหลายสถานี
Our machinery supports both 3-station and 4-station rotary configurations depending on the complexity of your product. The 4-station model provides an additional thermal conditioning step, critical for challenging resins.
แม่พิมพ์ 3 สถานี: Standard configuration for high-speed output.
แม่พิมพ์ 4 สถานี: Advanced setup for precise heat preservation and complex geometries.
High-precision mold processing yields a cavity surface roughness of Ra≤0.8μm. With optimized cooling channels, cycle times are reduced by up to 30%. Because these multi-station molds are highly intricate, proper wiring and integration are essential. Below is a closer look at our sophisticated mold wiring architecture:

5. ระบบควบคุมส่วนกลาง
Equipped with a highly robust, independent control system, the machine achieves precise synchronization across all stations via multi-axis motion control. It features adaptive optimization of process parameters and remote monitoring capabilities to maximize uptime and facilitate rapid troubleshooting.
Versatile Material Applications & Product Outputs
By providing highly targeted โซลูชั่นเครื่องเป่าขึ้นรูปพลาสติกแบบขั้นตอนเดียวที่ประหยัดพลังงาน, Ever Power enables the processing of a vast array of thermoplastic resins:
- สัตว์เลี้ยง: Exceptional transparency and barrier properties; widely used for beverage bottles and food packaging.
- พีพี: Excellent heat resistance (>120℃) and chemical tolerance; ideal for hot-fill juices, tea bottles, and medical containers.
- PETG: High toughness, excellent clarity, and zero stress-whitening; the preferred choice for heavy-walled cosmetics (mascara, lip gloss, premium skincare jars).
- พีซี (โพลีคาร์บอเนต): Supreme impact strength and thermal resistance; perfect for baby feeding bottles and reusable sports cups.
The equipment is capable of producing round, oval, or complex asymmetrical containers ranging from tiny 5ml cosmetic vials up to large 20L water barrels.
The Critical Importance of the Matched Air Compressor
A high-performance one-step ISBM machine relies heavily on a stable, high-pressure air source. The radial expansion of the preform inside the blow mold requires immediate, powerful bursts of air. If the pressure fluctuates, the resulting bottles will suffer from uneven wall thickness, poor dimensional accuracy, or incomplete thread formations.
Furthermore, because these containers are predominantly used in the food, beverage, and pharmaceutical industries, it is an absolute requirement that the blowing air is 100% clean and oil-free to prevent product contamination. Ever Power supplies specialized, matched oil-free screw air compressors calibrated perfectly to the CFM and pressure demands of the EPY200-V4, ensuring your entire line runs smoothly, hygienically, and with zero defect rates.

คำถามที่พบบ่อย (FAQ)
1. Can the EPY200-V4 directly replace my existing Aoki 250 machine?
Yes, it is designed as a highly capable upgrade or replacement for legacy 250-class machines. It offers comparable platen sizes and clamping forces, allowing you to achieve the same or higher production output while benefiting from modern full-servo energy efficiency.
2. How much energy does this machine actually save?
By using high-efficiency servo motors instead of continuously running hydraulic pumps, and by utilizing the one-step process’s inherent direct-heat retention, operators typically see a 30% to 40% reduction in electricity consumption compared to traditional hybrid or hydraulic ISBM models.
3. Will my team need extensive training to operate the new control system?
No. The smart multi-axis PLC features an intuitive touchscreen interface. We also provide comprehensive on-site installation, debugging, and operator training to ensure your team is fully comfortable running and maintaining the equipment.
4. How does the 4-station configuration help with thick-walled cosmetic jars?
Thick-walled materials like PETG require precise temperature profiling before stretching. The additional 4th station allows for dedicated thermal conditioning (heat preservation), preventing rapid cooling that leads to stress whitening or structural weakness in the final jar.
5. What are the long-term maintenance costs like compared to Western brands?
Maintenance costs are significantly lower. We utilize standardized, globally recognized electrical and pneumatic components. This means spare parts are not aggressively marked up, and you can easily source standard replacements locally in your own country, reducing both downtime and freight costs.
