One Step Blow Molding Machine EPY250-V4: 4-Station ISBM Powerhouse (ASB-70DPH Compatible)
The Industrial Standard for Large-Scale PET Container Manufacturing
Overview: Engineering Scale and Precision
In my two decades of optimizing polymer processing lines, the most significant bottleneck I've observed for growing manufacturers is the "Scaling Trap"—the difficulty of moving from mid-range production to high-volume output without scrapping existing tooling investments. The EPY250-V4 is Ever-power's strategic answer to this challenge. It is a heavy-duty, 4-station One Step Blow Molding Machine specifically engineered to be structurally and operationally compatible with the ASB-70DPH mold series.
Weighing in at a massive 16 tons, this machine is not a lightweight contender. It is built for stability. With a 300KN Injection Clamping Force and an extended upper mold stroke of 640mm, the EPY250-V4 allows for the production of deeper, taller, and more complex containers than standard models. Whether you are running 14 cavities for 30ml pharmaceutical vials or 2 cavities for 2.5L handles-ware, the result is the same: absolute consistency.
By integrating a 67.7KW Servo Pump System and a robust 15KW heating unit, this ISBM Machine bridges the gap between energy efficiency and raw hydraulic power. It represents the pinnacle of One Step PET Bottle Machine technology, offering a "Drop-in Replacement" capability for legacy Japanese machinery at a fraction of the capital expenditure.

Core Technology Speed Read (Power & Compatibility)
- ✔ ASB-70DPH Compatibility: Zero tooling waste. Run your existing ASB-70DPH molds directly on the EPY250-V4.
- ✔ Extended Stroke (640mm): The upper mold stroke is increased to 640mm, facilitating easier robot automation and taller bottle ejection.
- ✔ 300KN Injection Force: High-tonnage clamping guarantees high-density preforms free of flash, even with high-viscosity materials like PC or Tritan.
- ✔ 4-Station Architecture: Injection → Conditioning → Stretch Blow → Ejection. The definitive process for optical clarity.

4-Station Process: The "Hot Preform" Advantage
The EPY250-V4 utilizes the latent heat from the injection process 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 (EPY250-V4) | 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 One Step Injection 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 14 cavities) makes the EPY250-V4 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 EPY250-V4 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 EPY250-V4 for various green manufacturing subsidies.
