One Step Injection Stretch Blow Molding ISBM Machine HGYS280-V6: The 6-Station Twin-Screw Revolution
Engineered by Ever-power | 6-Station Thermal Precision | Twin-Screw Injection Technology
Engineering Overview: Redefining Optical Clarity with 6 Stations
In the hierarchy of polymer processing, the transition from 4-station to 6-station architecture marks the difference between “standard” and “luxury.” As an engineer specializing in high-viscosity PET and PCTG applications, I present the HGYS280-V6. This is not merely a One Step Blow Molding Machine; it is a thermal management masterclass designed for brands that demand glass-like aesthetics.
The HGYS280-V6 operates on an advanced 6-station rotary indexing system. Unlike standard machines, it incorporates dedicated conditioning and cooling stations that decouple the cooling phase from the injection cycle. This allows for the production of heavy-wall cosmetic jars and complex pharmaceutical vials with zero haze and absolute dimensional stability. Furthermore, it features a pioneering Twin-Screw Injection System heated by nano-far-infrared technology. This ensures superior melt homogeneity, making it the industry benchmark for processing rPET (recycled PET) and color-sensitive masterbatches without streaking.

Core Technology: The 6-Station ISBM Process
The One Step PET Bottle Machine maximizes quality by adding specialized stages to the standard cycle. The HGYS280-V6 utilizes 6 distinct stops on the rotary table, allowing for thermal history manipulation impossible on 3-station machines.

1. Twin-Screw Injection
Molten PET is injected using a specialized twin-screw unit. This ensures exceptional mixing homogeneity, critical for recycled PET (rPET) or color masterbatches.
2. Pre-Cooling
A dedicated station to begin the cooling of thick preforms gently, preventing crystallization in the gate area.
3. Temperature Conditioning
The preform core and skin temperatures are equalized to the exact orientation temperature. This decoupling from injection time allows for faster overall cycles.
4. Stretch & Blow
Biaxial orientation. The 200KN clamping force ensures precision molding of intricate details without parting lines.
5-6. Ejection & Buffer
Automated removal and buffering. The extra station can be used for in-line quality checks or post-cooling.
Why Choose the HGYS280-V6? Core Advantages
- ✓
Twin-Screw Technology: Unlike standard single screws, our twin-screw design provides high-shear mixing. This is a game-changer for rPET processing, ensuring no un-melted solids or color streaks. - ✓
6-Station Thermal Control: By separating cooling/conditioning from injection, we can mold thicker preforms (for heavy jars) without extending the cycle time, boosting productivity by 20-30%. - ✓
Energy Efficiency: Utilizing Nano-far-infrared heating rings (10KW) and servo-driven pumps, the machine reduces energy consumption significantly compared to traditional hydraulic systems. - ✓
High Cavitation for Vials: Capable of running up to 10 cavities for 20ml pharmaceutical vials, ensuring high output with medical-grade precision.

| Comparison Dimension | Ever-power One-Step ISBM | Traditional Two-Step (Reheat) |
|---|---|---|
| Process Flow | Resin -> Bottle (Integrated) | Resin -> Preform -> Cool -> Reheat -> Bottle |
| Energy Efficiency | High (Uses latent injection heat) | Low (Wastes energy reheating preforms) |
| Surface Quality | Flawless (No scuffing/scratches) | Risk of transport scratches on preforms |
| Applicable Materials | PET, PETG, PC, Tritan, PPSU, rPET | Mostly limited to virgin PET/PP |
| rPET Capability | Superior (Twin-screw mixing) | Variable (Dependent on preform quality) |
| Hygiene Level | Medical/Food Grade (Touchless) | Standard (Exposed to open air storage) |
Industry Applications
High-End Cosmetics
The ISBM Blow Molding Machine with 6 stations ensures that thick-walled cream jars cool evenly, preventing vacuum voids and ensuring a heavy, glass-like feel.
Pharmaceuticals
For eye drops (10ml-20ml), the HGYS280-V6 offers a clean, touchless environment. The 10-cavity setup provides high volume output for sterile packaging needs.
Recycled PET (rPET)
Brands moving to sustainability choose this machine. The twin-screw injection ensures that rPET, which often varies in viscosity, is homogenized perfectly for a consistent bottle strength and clarity.

Power System Selection Summary: Ever-power vs. Competitors
While Japanese 6-station machines (like ASB or Aoki) set a high bar, the HGYS280-V6 offers a competitive edge in ROI.
The Ever-power Guarantee: We utilize the same premium supply chain (Yaskawa servos, Parker hydraulics) but optimized for a lower capital expenditure. You get 95% of the performance for 60% of the price.
ROI Case: rPET Cosmetic Bottle Line
Switching from virgin PET to rPET using the HGYS280-V6:
- Material Savings: Capability to run up to 100% rPET reduces reliance on volatile virgin resin markets.
- Process Stability: Twin-screw mixing reduces scrap rate from color streaking by ~15%.
- Payback Period: Typically 12-16 months due to material cost optimization and premium product positioning.

Engineer’s FAQ
Why use a Twin-Screw design?
Standard single screws can struggle to mix color masterbatches into rPET evenly. Our Twin-Screw design provides high shear mixing, ensuring a perfectly uniform color and melt temperature.
What is the benefit of 6 stations over 4?
The extra stations allow for dedicated cooling/conditioning. This means we can cool the preform longer (essential for thick walls) without stopping the injection or blowing steps, effectively shortening the cycle time for heavy parts.
Do you provide installation?
Yes, we send engineers globally for installation, commissioning, and training of your staff.
