One Step Blow Molding Machine EPY200-V4-B: Heavy-Duty 4-Station ISBM (Aoki 250 Compatible)
The Ultimate One Step PET Bottle Machine for High-Volume Cosmetic & Pharma Production
Overview: Seamless Integration, Superior Performance
In my 20 years of optimizing polymer processing lines, the biggest challenge for many manufacturers has been upgrading capacity without discarding valuable legacy tooling. The EPY200-V4-B is engineered specifically to solve this. It is a robust 4-station One Step Blow Molding Machine that is structurally compatible with the Japanese Aoki 250 series molds. This means you can leverage Ever-power's modern servo-hydraulic technology while utilizing your existing mold inventory.
This "Type-B" variant is a beast of a machine, weighing in at 13 tons with extended strokes (Upper: 600mm, Lower: 350mm) to accommodate deeper cavities and taller containers. With a massive 300KN Injection Clamping Force and 250KN Blowing Clamping Force, it surpasses standard models, ensuring flash-free parting lines even on heavy-wall cosmetic jars.
Equipped with a 49.2KW Servo Pump System and a high-capacity 15KW Nano-infrared heating unit, this ISBM Machine delivers the thermal consistency required for premium PET/PETG containers. Whether you are producing 2.5L wide-mouth jars or precision 10ml vials in a 12-cavity setup, the EPY200-V4-B offers the stability of a Japanese machine at a significantly more attractive ROI.

4-Station "Hot Preform" Process Technology
The EPY200-V4-B leverages the latent heat from injection to blow the bottle, ensuring optimal molecular orientation without the energy waste of reheating.
1. Injection
Molten PET is injected into the preform mold. 300KN clamping ensures high-density, flash-free preforms.
2. Conditioning
CRITICAL: Temperature equalization. The core retains heat while the skin is cooled, allowing for complex shape stretching.
3. Stretch Blow
Stretch rod extends the preform axially, followed by high-pressure air (3.5Mpa) for radial expansion.
4. Ejection
Finished bottles are stripped from the core rod and ejected, ready for packing.
Process Audit: One-Step (ISBM) vs. Two-Step
| Feature | Ever-power One-Step (EPY200-V4-B) | Two-Step Process |
|---|---|---|
| Bottle Aesthetics | Flawless, Scuff-Free | Scratches from preform tumbling |
| Energy Efficiency | High (Utilizes injection heat) | Low (Requires reheating cold preforms) |
| Hygienic Grade | Medical / Pharma Ready (Hands-free) | Standard Industrial |
| Neck Precision | Exact Tolerance (Molded) | Variable (Distortion risk during reheat) |
| Space Required | Compact (1 Machine) | Large (Injection + Reheat + Blow + Storage) |
Industry Applications
Pharmaceutical Packaging
Ideal for mass production of eye drop bottles, pill packers, and syrup bottles. The Injection Stretch Blow Molding Machine process ensures clean room compatibility.
Cosmetic Jars
Specifically designed for wide-mouth cream jars and lotion bottles. The 300KN clamping force ensures zero parting lines on the base, a requirement for luxury brands.
Food & Spice Containers
High-cavity output (up to 12 cavities) makes the EPY200-V4-B perfect for small spice jars and condiment bottles where unit cost is critical.
[Saudi Arabia] Extreme Heat Hydraulic Performance Study
In regions like the Middle East where ambient temperatures soar, standard hydraulic machines suffer. The EPY200-V4-B combats this with an Oversized Oil Cooling System (requiring 0.3-0.4 Mpa water pressure) and Servo-Driven Pumps that generate significantly less heat than constant volume systems. This ensures the 300KN clamping force remains stable even at 45°C ambient temperatures.
[Germany] Energy Efficiency & EuP Compliance
Our servo systems operate on a "Power-on-Demand" basis. During cooling or idle phases, energy consumption drops to near zero. This architecture aligns with strict EU energy efficiency directives, qualifying the EPY200-V4-B for various green manufacturing subsidies.

Yes, we offer specialized bimetallic screws and drying systems optimized for rPET processing to prevent yellowing.
3. Does it require a chiller?
Yes, precise mold temperature control (10-15°C) is vital. We can supply the appropriate chiller unit as part of the package.
4. What is the typical cycle time?
For standard pharmaceutical bottles, cycle times range from 12 to 15 seconds, depending on wall thickness and cooling efficiency.
5. Is installation included?
We provide comprehensive onsite installation, commissioning, and staff training services worldwide.
6. How does the conditioning station help?
It allows the preform skin to cool while keeping the core hot. This is essential for stretching non-round shapes without rupturing.
