Description
EP-HGY250-V4 Large-Frame 4-Station One-Step Injection Stretch Blow Molding Machine Overview
The EP-HGY250-V4 is a large-frame, high-output 4-station one-step injection stretch blow molding machine designed for manufacturers requiring the maximum combination of cavity count, container size range, and production volume within a 4-station ISBM platform. With a 640mm upper mold stroke — the longest in the EP-HGY 4-station series — it supports the production of containers with total preform heights that are impossible on smaller machines.
Uniquely, the EP-HGY250-V4 offers direct ASB-70DPH mould format compatibility, enabling manufacturers currently operating or converting from Japanese ASB 70DPH-class equipment to carry over existing tooling investments without modification. This mould compatibility, combined with a 420g theoretical injection volume (55mm screw), positions this machine as the natural upgrade path for high-volume cosmetic, pharmaceutical, food, and personal care bottle production lines.
At 82.7KW total power, 16 tonnes, and a machine footprint of 6300×2400×3700mm, the EP-HGY250-V4 is a production-grade workhorse capable of driving high-volume dedicated bottle lines across 1 to 14 cavity configurations. Explore the full EP-HGY series on our ISBM machines page.

The turntable is driven by a Japan Yaskawa servo motor with a Taiwan TSUNTIEN reducer, providing reliable high-torque indexing across the machine’s large-diameter turntable. YUKEN hydraulic control valves (Taiwan) manage both injection and blow clamping circuits. Italian-sourced hydraulic tubing throughout ensures circuit integrity and consistent performance in continuous multi-shift high-volume production environments.
Engineering Specifications & Performance Highlights
ASB-70DPH Mould Compatibility
Direct compatibility with Japanese ASB-70DPH mould format enables manufacturers to transfer existing high-value tooling assets to the EP-HGY250-V4 without modification. For the many production lines worldwide running ASB 70DPH equipment, this compatibility is the defining reason to choose this model.
640mm Upper Mold Stroke — Series Maximum
At 640mm the EP-HGY250-V4 achieves the longest upper mold stroke in the 4-station EP-HGY series. This enables production of containers with tall preform profiles — up to 220mm bottle height in 2-cavity configuration — and provides the mechanical clearance required to run the full range of ASB-70DPH mould geometries.
Up to 14 Cavities Per Cycle
Supporting 1 to 14 cavities, the EP-HGY250-V4 achieves production rates typically reserved for dedicated high-speed rotary blow molding lines — while maintaining the ISBM process’s superior barrier properties, optical clarity, and product consistency.
420g Injection Volume (55mm Screw)
The 420cm³ theoretical injection volume with 55mm screw accommodates heavier preforms for large-volume containers and multi-cavity configurations requiring significant shot weight per cycle. The 420g shot capacity covers the full range of container sizes from 30ml miniatures to 2,500ml large-format bottles.
15KW Nano Far-Infrared Heating
The screw and barrel use a 15KW nano far-infrared energy-saving heating ring — a higher-capacity heating system reflecting the machine’s larger barrel assembly. This ensures uniform melt temperature across the full injection volume range, reducing startup waste and improving first-shot quality.
600L Oil Tank Capacity
The 600L hydraulic oil tank (double the capacity of the EP-HGY150/200 series) provides superior thermal stability during continuous high-cycle production. Larger oil volume means slower temperature rise per cycle, extending oil service life and reducing the risk of thermal-related hydraulic response variation during long production runs.

Customer Case Studies
Japan — Premium Cosmetics Manufacturer
Cosmetics | 180mm wide-diameter premium face cream jars, 4-cavity, ASB-70DPH tooling
“We designed our signature face cream jar on ASB-70DPH tooling over a decade ago. When we needed to add production capacity, the EP-HGY250-V4 was the only non-ASB machine that accepted our existing mould bases directly. First production run on the EP-HGY250-V4 required only minor parameter adjustment — the bottle dimensions were within specification from the first cycle.”
★★★★★
Australia — Water Container Manufacturer
Beverage | 2,500ml wide-mouth water containers, 2-cavity
“We needed ISBM process quality — superior clarity and oxygen barrier — in a large 2,500ml wide-mouth format. The EP-HGY250-V4 was the only machine in the mid-size ISBM category with the 200mm bottle diameter capability and 640mm stroke we needed. Production clarity is dramatically better than our previous EBM containers.”
★★★★★
Colombia — Food Packaging
Food | 750ml sauce jars and 1500ml wide-mouth food containers, 3 and 2-cavity
“The 14-cavity capability at smaller bottle sizes means we can run our 30ml portion-control sauce bottles at industrial output, then switch the same machine to 3-cavity 750ml jars for our retail line. No other machine in this class gives us that range. The changeover takes about 90 minutes.”
★★★★☆
United Kingdom — Supplement Brand
Nutraceuticals | 1,000ml protein powder containers wide-mouth, 4-cavity
“The wide-mouth capability combined with the ISBM process’s superior barrier performance was the deciding factor. Our previous extrusion blow molded containers had oxygen ingress issues affecting product shelf life. The EP-HGY250-V4’s biaxial stretch orientation gave us the barrier improvement we needed without switching to more expensive multilayer packaging.”

Frequently Asked Questions — EP-HGY250-V4
What makes the EP-HGY250-V4 different from the EP-HGY200-V4-B?
The EP-HGY200-V4-B is engineered for AOKI-250 mould compatibility with a 600mm upper mold stroke and 13T weight, suited for tall-profile personal care and pharmaceutical bottles. The EP-HGY250-V4 is engineered for ASB-70DPH mould compatibility with a 640mm upper mold stroke, 200mm maximum bottle diameter (versus 118mm on the V4-B), and a 600L oil tank — positioned for wider-diameter, larger-format containers and higher output per cycle. The key decision factor is which mould format your existing tooling uses and what maximum bottle diameter your production requires.
Can the EP-HGY250-V4 run existing ASB-70DPH moulds without any machine-side modification?
In most cases, yes. The machine’s injection and blow station dimensions are matched to ASB-70DPH standard specifications. However, we strongly recommend sharing your specific mould drawings with our team before finalising the purchase order — some older or customised ASB-70DPH moulds may have non-standard features. Submit your mould drawings and our engineering team will provide a formal compatibility assessment within 5 business days.
How does the 600L oil tank affect production performance?
The 600L oil tank provides significantly larger thermal mass in the hydraulic circuit compared to the 300L tanks on smaller EP-HGY machines. In sustained high-output production, this larger volume means hydraulic oil temperature rises more slowly per production hour — reducing the risk of thermal expansion-related hydraulic response variation across long shifts. This is particularly important when running 10–14 cavities at maximum cycle rates where hydraulic heat generation is at its highest.
What screw sizes are available and which is recommended for large-format bottle production?
Three screw diameters are available: 50mm (340cm³), 55mm (420cm³), and 60mm (480cm³). For large-format containers in the 500ml–2,500ml range — particularly at 2 to 5 cavities — the 55mm or 60mm screw is recommended to provide sufficient shot volume per cycle. For high-cavity configurations at smaller bottle sizes (8–14 cavities, 30ml–200ml), the 50mm screw with its higher rotational speed (180 RPM) provides faster plastication to maintain target cycle times.
Is the EP-HGY250-V4 suitable for producing bottles with complex asymmetric profiles?
The one-step ISBM process on this machine supports complex bottle profiles including non-round cross-sections, pronounced shoulder tapers, and significant body geometry variation — advantages that conventional two-step reheat stretch blow machines struggle to replicate consistently. The 640mm upper mold stroke and dual servo motor mold clamping option provide the mechanical range and clamping precision needed for complex asymmetric blow mold geometries.
Unlock Large-Format & High-Cavity ISBM Production
The EP-HGY250-V4 combines ASB-70DPH mould compatibility, 640mm stroke, and 14-cavity capability in a single platform — delivering the large-frame ISBM performance that ambitious packaging operations require.
