In the competitive landscape of plastic container manufacturing, speed and energy efficiency define your profitability. Discover how upgrading to a servo-driven architecture revolutionizes your production line.

The ISBM Advantage: Streamlined Production
One-step Injection Stretch Blow Molding (ISBM) is an incredibly efficient forming process utilized for manufacturing high-precision, visually flawless hollow plastic products. This includes baby feeding bottles, water cups, pharmaceutical vials, and luxury cosmetic jars made from PET, PETG, PP, PC, Tritan, PS, ABS, and PLA.
The defining characteristic of this technology is that injection, stretching, and blow molding are seamlessly executed in a continuous sequence within a single machine. By eliminating intermediate handling, preform storage, and secondary reheating, you drastically elevate both production efficiency and product consistency.
The 4-Station Process Flow
- 1. Inyección: Resin is melted and injected to form a highly accurate preform.
- 2. Corte de cola de preforma / Conservación del calor: The preform’s temperature is optimally conditioned for perfect stretching.
- 3. Moldeo por soplado y estirado: Simultaneous axial stretching and radial blowing create the final bottle shape.
- 4. Botella para llevar: Automated ejection ensures high-speed, hygienic packaging.
Core Production Advantages
- Alta eficiencia y ahorro energético: Directly utilizes residual heat from the injection phase, bypassing expensive reheating ovens to lower energy consumption by approximately 40%.

Composición del equipo y tecnologías clave
To understand how we deliver such high output, we must look at the five critical systems that make up our Soluciones de máquinas de moldeo por soplado de un solo paso y alta eficiencia energética.
1. Sistema de inyección de alta precisión
The injection unit utilizes a high-precision servo drive to ensure the molten plastic is perfectly uniform. A critical component of this success is our exclusive patented screw and barrel design.
Our patented screw design guarantees homogeneous melting and fast recovery times.
- High-precision temperature control system (accuracy maintained at ±1℃).
- Servo-driven injection unit providing rapid response and ultra-high repeat accuracy.
- Advanced preform wall thickness control system (axial and radial optimization).
2. Sistema de calefacción adaptativo
Utilizing zoned heating control, the system achieves precise temperature profiling across different preform sections. Non-contact temperature measurement strictly prevents surface damage, and the system automatically adapts heating power based on live production speeds to maximize energy efficiency.
3. Sistema de soplado y estiramiento sincronizado
Driven by advanced mechanisms, this module executes rapid axial stretching (up to 400mm/s with an exact position accuracy of ±0.1mm) and radial blowing. High-pressure gas is strictly managed by independent regulating valves, keeping fluctuations tightly controlled within ±0.05MPa to ensure perfect stretch-blow synchronization.
4. Advanced Multi-Station Mold System
We utilize rotating multi-station structures perfectly tailored to specific material needs. Below is the difference between our high-output 3-station layout and our advanced 4-station layout, which adds a dedicated heat preservation step for challenging resins like PETG or PC.
Molde de 3 estaciones: Injection, Blow Molding, Ejection (Ideal for rapid PET/PP output).
Molde de 4 estaciones: Injection, Heat Preservation, Blow Molding, Ejection (Essential for PETG/PC clarity).
Our precision mold cavities achieve a surface roughness of Ra≤0.8μm. Optimized internal cooling channels cut cycle times by 30%, and rapid tooling technology enables mold swaps in under 60 minutes. The intricate wiring required for these high-precision rotary molds is meticulously integrated:

We don’t just supply machines; we design and manufacture custom high-precision molds tailored to your specific container designs.

5. Smart Centralized Control System
An independent, multi-axis motion control system manages exact station synchronization. It dynamically optimizes process parameters based on live production data and includes a remote monitoring and fault diagnosis system to drastically reduce downtime.
Diverse Material Applications & Product Outputs
Our servo-driven architecture allows for vast flexibility, easily adapting to different thermoplastics to capture market trends:
- MASCOTA: Exceptional transparency and barrier properties; ideal for beverage bottles, water cups, and food jars (capacities from 5ml to 20L).
- PÁGINAS: Excellent heat resistance (>120℃), perfect for hot-fill juices, tea bottles, and durable medical packaging.
- PETG: Unmatched toughness and zero stress-whitening; the standard for premium cosmetic packaging (thick-walled jars, lip gloss, mascara tubes).
- PC (Policarbonato): Superior impact and heat resistance; heavily used for infant feeding bottles and reusable space cups.


Critical Setup Advice: The Role of Oil-Free Air Compressors
When installing Equipo de soplado de botellas de un solo paso, the quality of your auxiliary systems is just as important as the primary machine. The stretch blow molding phase requires massive, instantaneous volumes of high-pressure compressed air to force the preform against the mold walls perfectly.
If this air pressure fluctuates, the resulting containers will suffer from uneven wall thickness, deformed threads, and an unacceptable scrap rate. Furthermore, since these bottles are used for cosmetics, food, and pharmaceuticals, the air entering the bottle must be 100% clean. Standard compressors blast microscopic oil droplets into the air line, contaminating the interior of your products.
To guarantee flawless production, Ever Power provides specialized, Compresores de aire de tornillo sin aceite 100%. These units are precisely matched to the pressure demands of our ISBM machines, ensuring absolute stability and clinically pristine air to safeguard your final product quality.

Preguntas frecuentes (FAQ)
1. How exactly do dual servo-motors improve production speed?
Dual servo-motors allow for simultaneous, highly responsive movements across the injection and mechanical forming stages. This drastically reduces the dry cycle time (the time the machine takes to reset between forming actions), resulting in a much higher output per hour compared to traditional single-drive systems.
2. Can I use my old molds on the Ever Power ISBM machine?
Yes. Our machines are intentionally engineered with platen dimensions and tie-bar clearances that match widely used Japanese ASB and Aoki molds. This universal compatibility ensures you can upgrade your production speed without abandoning your current tooling investments.
3. Why is a 4-station machine necessary for PETG and PC materials?
Complex resins like PETG and PC have narrow processing temperature windows. A 4-station machine incorporates a dedicated heat preservation step between injection and blowing. This precisely conditions the preform, preventing the material from cooling too quickly and causing stress whitening or haze in the final product.
4. How difficult is it to change molds on a rotary machine?
While multi-station molds are complex, our equipment features rapid tooling changeover technology. With a trained team, a complete mold swap can be efficiently executed in under 60 minutes, ensuring your production downtime is kept to an absolute minimum.
5. Do you provide training for operating the control system?
Yes. Our independent multi-axis control system features an intuitive touch interface. Ever Power provides comprehensive on-site installation, debugging, and operational training, ensuring your technical team is fully confident in maximizing the machine’s capabilities.
