EP-HGY200-V4-B AOKI-250 Compatible 4-Station One-Step Injection Stretch Blow Molding Machine
The EP-HGY200-V4-B is a specialised 4-station one-step injection stretch blow molding machine engineered as the definitive upgrade and conversion platform for manufacturers currently operating — or seeking to replace — Japanese AOKI 250-class ISBM equipment. With direct AOKI-250 mould format compatibility, existing tooling investments can be transferred to this machine without modification, eliminating the single largest cost barrier in ISBM equipment conversion projects.
The machine’s most distinguishing specification is its 600mm upper mold stroke — the longest in the EP-HGY200 series — enabling production of tall-profile containers that shorter-stroke ISBM machines cannot physically accommodate. Combined with an elevated 250KN blowing clamping force (versus 200KN on the standard V4) and a 442g theoretical injection volume, the EP-HGY200-V4-B handles heavier, larger preforms with the clamping rigidity required for high-quality large-format container production.
Supporting up to 12 cavities per cycle and a maximum container volume of 2,500ml, this machine serves manufacturers in personal care, pharmaceutical, food, and industrial packaging who need tall-bottle ISBM capability with the tooling flexibility of AOKI-250 format compatibility. Explore how it fits your operation on our ISBM machines overview or discuss your mould compatibility requirements with our engineering team.

4-Station Process Flow
The turntable operates on a Japan Yaskawa servo motor with Taiwan TSUNTIEN reducer, providing the high-torque, low-vibration indexing precision required for consistent preform positioning across all 12 cavity positions. YUKEN hydraulic pressure control valves (Taiwan) manage the injection and blow clamping circuits, while Italian-imported hydraulic tubing ensures circuit integrity in continuous production environments.
Key Engineering Differentiators — EP-HGY200-V4-B
AOKI-250 Mould Direct Compatibility
The machine’s injection station platen dimensions, tie-bar spacing, and blow station geometry are designed to accept AOKI-250 standard mould bases directly — no adaptation plates or machine modifications required. This is the primary reason manufacturers converting from AOKI 250-class equipment choose this model.
600mm Upper Mold Stroke — Class-Leading
At 600mm, this machine offers the longest upper mold stroke in the EP-HGY200 series and one of the longest available in 4-station ISBM machines. This enables production of tall-profile containers — up to 280mm in height in 1-cavity configuration — that are physically impossible on machines with shorter stroke travel.
250KN Blowing Clamping Force
An upgraded 250KN blowing clamping force (versus 200KN on the standard V4) provides additional mold closure security when producing tall, thin-wall containers where blow pressure forces are distributed over a larger projected mold area.
442g Theoretical Injection Volume
The higher theoretical injection volume of 442cm³ (50mm screw) versus 310cm³ on the standard V4 allows the EP-HGY200-V4-B to injection-mold heavier preforms per shot — enabling larger-volume containers and thicker-wall specialty bottles that require more PET material per unit.
12-Cavity High-Output Capability
Supports 1 through 12 cavities per cycle. The combination of AOKI-250 mould compatibility and 12-cavity support means manufacturers can run existing AOKI tooling at maximum productivity from day one of operation.
Nano Far-Infrared Screw Heating
The screw and barrel heating system uses a 15KW nano far-infrared energy-saving heating ring — an upgrade from the standard 10KW system on the V4 — reflecting the machine’s larger screw barrel assembly and higher injection volume requirements.

Application Scenarios — Where the EP-HGY200-V4-B Excels
The EP-HGY200-V4-B addresses production needs that standard 4-station ISBM machines cannot meet — tall containers, AOKI tooling conversion, and high-blow-force applications:
Tall-Profile Personal Care Bottles
280mm-height personal care containers — pump dispensers, tall lotion bottles, elongated body wash — that require the 600mm upper mold stroke to accommodate the full preform injection and conditioning cycle. These tall profiles are the defining application for the EP-HGY200-V4-B.
AOKI-250 Equipment Conversion
Manufacturers replacing ageing AOKI 250-class ISBM machines can transfer their entire mould inventory directly to the EP-HGY200-V4-B — maintaining bottle SKU continuity while gaining modern servo pump efficiency, updated PLC control, and full Ever Power after-sales support.
Tall Pharmaceutical Containers
Tall pharmaceutical packaging — liquid medicine bottles, large-volume oral supplement containers, and multi-pack tablet bottles — requiring both AOKI mould compatibility and the 600mm stroke to produce full-height preforms for tall neck-to-base profiles.
High-Volume Daily Chemical
Large-format daily chemical bottles at 10–12 cavity for FMCG production targets. The AOKI-250 compatibility allows manufacturers with established formulations and existing AOKI tooling to move to higher-output production without retooling.
Mould Compatibility & AOKI-250 Conversion
The EP-HGY200-V4-B is the only machine in the EP-HGY200 series with direct Japanese AOKI-250 mould format compatibility. The machine’s injection station platen and blow station dimensional envelope match AOKI 250-class specifications precisely — allowing manufacturers to install AOKI-250 standard mould bases directly without adaptation fixtures, platen drilling, or machine modifications.
For manufacturers combining new bottle development with AOKI tooling conversion, Ever Power’s mould engineering team can produce new cavity inserts to AOKI-250 mould base standards — enabling you to use new and existing AOKI-format tooling interchangeably on the same machine. Full mould qualification documentation is provided with every new mould development.

Customer Case Studies
Japan — Cosmetics Bottle Manufacturer
Cosmetics | Tall 280mm profile PETG bottles for luxury brand, AOKI-250 tooling transferred
“We had 14 sets of AOKI-250 moulds representing a substantial tooling investment. When our AOKI machine needed replacement, the EP-HGY200-V4-B allowed us to transfer all 14 mould sets directly with zero adaptation. First production run dimensional results were within our existing bottle specifications. We saved the cost of a complete tooling remake, which was the equivalent of a second machine purchase.”
★★★★★
Germany — Pharmaceutical Packaging
Pharma | 200ml tall oral liquid medicine bottles at 6-cavity, AOKI tooling
“Our AOKI machine was at end of service life with parts becoming difficult to source. The EP-HGY200-V4-B transition kept our validated bottle specifications unchanged — same mould, same neck dimensions, same bottle geometry. Our regulatory team could reference the existing validated bottle design without resubmission.”
★★★★★
South Korea — Personal Care
Personal Care | 250ml tall pump dispenser bottles for skincare brand, 8-cavity
“The 600mm upper mold stroke was the critical specification for our tall pump dispenser bottle. Our previous conventional ISBM machine could not accommodate the preform height. The EP-HGY200-V4-B’s extended stroke resolved this immediately. We’re now running 8 cavities at a cycle time competitive with our previous 4-cavity production on a shorter-stroke machine.”
★★★★☆
Brazil — FMCG Packaging
Daily Chemical | 400ml and 750ml body wash bottles at 12-cavity for retail brand
“The AOKI-250 mould format gave us access to a much wider secondhand mould market in South America — many ex-AOKI plants were selling mould sets that we could acquire at a fraction of new tooling cost. The EP-HGY200-V4-B made those moulds directly usable on a brand-new, fully supported machine.”

Frequently Asked Questions — EP-HGY200-V4-B
Will all AOKI-250 moulds fit directly without modification?
The EP-HGY200-V4-B is designed for direct mechanical compatibility with standard AOKI-250 mould bases. The injection station platen and blow station dimensional envelope match AOKI 250 specifications. However, some older or customised AOKI-250 format moulds may have non-standard features or modified platen interfaces — we recommend sharing your mould drawings with our engineering team before purchase for a formal compatibility assessment. Send us your mould drawings for evaluation.
How does the EP-HGY200-V4-B’s 600mm upper mold stroke affect cycle time?
A longer upper mold stroke means the upper mold platen travels a greater distance during each open/close cycle. This adds a small amount to the overall cycle time compared to shorter-stroke machines. However, the servo turntable’s optimised velocity profile and the machine’s ability to partially overlap station movements minimise the practical cycle time impact. For tall-bottle applications where this machine is the only option, the cycle time trade-off is inherent to the geometry requirement.
What is the difference in blowing clamping force between the V4 and the V4-B?
The standard EP-HGY200-V4 provides 200KN blowing clamping force per side, while the EP-HGY200-V4-B provides 250KN. The additional 50KN reflects the larger mold projected area of tall-profile bottles — where the same internal blow pressure acts over a larger surface area, requiring greater clamping force to prevent mold parting during blowing.
Can the EP-HGY200-V4-B produce standard (non-tall) bottles as well?
Yes. The 600mm upper mold stroke is the machine’s maximum travel capability — it does not require the full stroke range for shorter bottles. For standard-height containers, the machine operates with a reduced stroke profile, maintaining the same cycle time efficiency as a shorter-stroke machine for those specific bottle heights. This makes the EP-HGY200-V4-B a versatile platform capable of running both tall-profile and standard-height bottles by simply changing moulds.
What heating power does the EP-HGY200-V4-B use versus the standard V4?
The EP-HGY200-V4-B uses a 15KW nano far-infrared heating ring on the screw and barrel assembly, compared to 10KW on the standard V4. This reflects the larger 50mm standard screw diameter and higher 442cm³ injection volume capacity of the V4-B. The higher heating power ensures adequate thermal input to process larger preform shots without excessive startup time or melt temperature variation across the injection volume range.
Convert Your AOKI-250 Line or Expand into Tall-Bottle Production
The EP-HGY200-V4-B removes the two largest barriers to ISBM line modernisation: tooling cost and tall-bottle capability. With direct AOKI-250 mould compatibility and a 600mm upper mold stroke, it delivers both without compromise. Talk to our engineering team about your mould inventory and production targets.
