What is One-Step Injection Stretch Blow Molding?
One-step injection stretch blow molding (ISBM) is a highly efficient plastic container forming process. It is widely used to produce high-precision, high-demand hollow plastic products such as cosmetic bottles, baby bottles, water cups, and pharmaceutical containers from various materials including PET, PETG, PP, PC, Tritan, PS, ABS, and PLA. The core defining feature is that the three major steps—injection, stretching, and blow molding—are completed continuously within the same equipment, entirely eliminating intermediate storage and reheating steps.
กระบวนการทำงานที่คล่องตัว
- 1. Injection: High-precision injection of molten resin into a cavity to form the preform with an exact neck finish.
- 2. Preform Tail Cutting / Heat Preservation: Conditioning the preform and utilizing its latent heat for the next phase.
- 3. Stretch Blow Moulding: Axial stretching and radial blowing of the hot preform into the final cosmetic bottle shape.
- 4. Bottle Take-out: Automated ejection of the finished, defect-free product.
ข้อได้เปรียบหลักและประโยชน์ของอุปกรณ์

Equipment Composition and Key Technologies
Our single stage ISBM equipment consists of five major integrated systems. Here is an inside look at the technology driving your cosmetic bottle manufacturing.
1. ระบบฉีด
The injection system uses a high-precision servo-driven unit equipped with a highly specialized barrel and screw to ensure uniform plastic melt plasticization. We proudly feature our patented screw design, engineered specifically to handle the delicate melting profiles required for high-clarity cosmetic plastics without causing material degradation.
Our Patented Injection Screw Design for Optimal Plasticization
- ระบบควบคุมอุณหภูมิความแม่นยำสูง (ความแม่นยำ ±1℃)
- Servo-driven injection unit (fast response, exceptional repeat accuracy).
- Preform wall thickness control system (optimizes thickness via precise axial or radial adjustments).
2. ระบบทำความร้อน
Utilizing advanced heating rings or a combination of water and oil temperature controls, paired with real-time temperature sensors.
- Zoned heating control (achieves precise temperature regulation across different sections of the preform).
- Non-contact temperature measurement (prevents any physical damage to the preform surface).
- Adaptive heating power (automatically optimizes parameters based on the current production speed).
3. ระบบการเป่าขึ้นรูปยืด (Stretch Blow System)
This system performs the critical axial stretching and radial blowing of the preform.
- Advanced stretch mechanism (stretching speeds up to 400mm/s with a positional accuracy of ±0.1mm).
- Independent high-pressure gas regulating valve system (strictly controls pressure fluctuations within ±0.05MPa).
- Stretch-blow synchronous control technology (ensures the exact coordination of the stretching and blowing phases).
4. ระบบแม่พิมพ์
The mold system typically employs a rotary multi-station structure. For cosmetic manufacturing, choosing the right station configuration is key. If you are operating with limited space, a เครื่องฉีดขึ้นรูปพลาสติกแบบขั้นตอนเดียวขนาดกะทัดรัดสำหรับโรงงานขนาดเล็ก equipped with our high-efficiency molds provides unparalleled output per square meter.
3-Station Mold Structure: This layout integrates injection, stretch blow molding, and ejection. It is highly efficient and perfect for standard travel-size cosmetic bottles and high-speed production runs.
4-Station Mold Structure: Incorporates an extra conditioning/temperature equalization station. This is vital for complex, thick-walled cosmetic jars requiring precise thermal management before blowing.
- High-precision mold machining technology (cavity surface roughness Ra≤0.8μm).
- Highly efficient cooling system (optimized cooling water channels reduce cooling time by 30%).
- Rapid mold change technology (complete changeovers in ≤60 minutes).

We Also Supply Premium Custom Molds
Along with our machines, Ever Power manufactures high-quality molds tailored to your specific cosmetic bottle designs.
5. ระบบควบคุม
Our independent, intelligent control system allows for centralized command and parameter optimization.
- Multi-axis motion control system (achieves exact synchronization across all working stations).
- Adaptive process parameter optimization (dynamically adjusts settings based on real-time production feedback).
- Remote monitoring and fault diagnosis (ensures maximum equipment uptime and stability).
Material Application & Travel-Size Product Types
As the ultimate one step blow molding equipment for cosmetic packaging, our technology flawlessly processes a diverse range of thermoplastic materials to meet specific product requirements:
- PET: Unbeatable transparency and high barrier properties. Perfect for travel-size toners, makeup removers, and beverage bottles.
- PETG: The gold standard for daily chemicals and color cosmetics (shampoos, shower gels, mascara, lip gloss, and thick-walled premium jars). It features superior viscosity, colorability, chemical resistance, and stress-whitening resistance.
- PP: Excellent chemical resistance and heat tolerance (above 120℃). Ideal for hot-fill processes or specific cosmetic formulations.
- PC: Outstanding strength and heat resistance. Frequently used for specialized packaging, baby bottles, and space cups.
High-Quality Finished Bottles Produced by Ever Power ISBM Machines
Crucial Integration: Oil-Free Blowing Air Compressors
When producing premium travel-size cosmetic bottles, achieving pristine clarity and exact dimensional accuracy is non-negotiable. This is where a high-quality blowing air compressor becomes a critical component of your production line. In the one-step stretch blow molding process, high-pressure compressed air is responsible for forcefully expanding the heated preform against the mold cavity walls. If the air supply fluctuates in pressure, it can lead to uneven wall distribution or structural defects in the final bottle.
Furthermore, for cosmetic packaging, the air must be absolutely clean, dry, and 100% oil-free. Any trace of oil or moisture introduced during the blowing stage will contaminate the interior of the bottle, ruining the optical clarity of materials like PETG and compromising the safety of the cosmetic product inside. Ever Power provides specially matched oil-free screw air compressors designed perfectly for our molding machines. These integrated compressors guarantee a stable, uninterrupted, and pure high-pressure air supply, ensuring your automated manufacturing runs smoothly with zero contamination, thereby maximizing your equipment’s performance and product yield.

คำถามที่พบบ่อย (FAQ)
1. What is the typical cycle time for a 50ml travel-size cosmetic bottle?
Depending on the material thickness and mold cavity quantity, cycle times for small travel bottles typically range from 12 to 20 seconds. Our advanced cooling channels ensure these speeds remain consistent.
2. Can we mold extremely thick-walled PETG bases commonly used in luxury cosmetics?
Yes, absolutely. For thick-walled products, we recommend our 4-station machine model. The extra conditioning station provides the precise thermal equalization needed to stretch thick walls without stress-whitening.
3. How difficult is it to switch between different bottle designs?
It is highly efficient. Our machines feature rapid mold change technology. A trained operational team can completely swap out the preform and blow molds in 60 minutes or less, maximizing your uptime.
4. Do I need to purchase a separate preform heating oven?
No. The defining advantage of our one-step process is that it utilizes the residual heat from the injection stage directly for the blowing stage. This eliminates the need for standalone heating ovens, saving both floor space and immense amounts of energy.
5. Are replacement parts readily available globally?
Yes. We utilize internationally standardized components for critical parts (like servo motors and valves) and maintain a comprehensive inventory of custom parts, ensuring rapid dispatch and support for our global clients.
