EP-HGY250-V4-B Dual-Row 4-Station One-Step Injection Stretch Blow Molding Machine Overview
เดอะ EP-HGY250-V4-B is a specialised dual-row 4-station one-step injection stretch blow molding machine engineered specifically to maximise production output for small-to-medium plastic containers. By arranging cavities in two parallel rows within the same machine cycle, the EP-HGY250-V4-B achieves cavity counts of up to 28 cavities per cycle — a throughput level that would otherwise require two separate ISBM machines operating in parallel.
This dual-row architecture is paired with a 680g theoretical injection volume (60mm screw), providing the shot capacity to fill all 28 preform positions in a single injection cycle. The machine’s three servo pump systems deliver precise, energy-responsive hydraulic control across all stations, while Italian-sourced hydraulic tubing and YUKEN control valves ensure long-term reliability at continuous high-cycle production rates.
The EP-HGY250-V4-B targets manufacturers producing high volumes of small containers — including pharmaceutical tablet bottles, cosmetic sample vials, travel-size personal care containers, and eye-drop bottles — where output per hour is the primary production economics driver. At 82.7KW total power and 16 tonnes, it delivers industrial-scale throughput in a single-machine footprint. Compare models on our ISBM machines overview.

Dual-Row 4-Station Process Architecture
In the dual-row configuration, the injection station mould contains two parallel rows of cavities — both rows are injected in a single shot. The temperature conditioning station maintains both rows simultaneously, and the blow station produces both rows in the same blow cycle. The take-out system retrieves all bottles from both rows in a single automated operation. This architecture doubles the effective cavity count without increasing machine cycle time, directly doubling production output versus an equivalent single-row configuration.
The turntable is driven by a Japan Yaskawa servo motor with Taiwan TSUNTIEN reducer. YUKEN hydraulic pressure control valves (Taiwan) manage the injection and blow clamping circuits. Italian-imported hydraulic tubing throughout the circuit provides the burst pressure integrity and vibration resistance required for continuous high-cycle operation.
Core Technical Advantages — EP-HGY250-V4-B Dual-Row ISBM
28-Cavity Dual-Row Output
The dual-row cavity layout achieves up to 28 cavities per production cycle — matching the output of two conventional single-row ISBM machines while occupying a single machine footprint and requiring only one operator. For high-volume small-bottle production, this represents a fundamental improvement in output per m² of factory floor space.
680g Injection Volume (60mm Screw)
The 680cm³ theoretical injection volume with the 60mm screw option provides the shot capacity to fill all dual-row preform positions in a single injection cycle. This large shot volume, combined with the machine’s 300KN injection clamping force, ensures uniform melt distribution and consistent preform weight across all 28 cavity positions.
Servo Pump Energy Efficiency
Three independent servo pump systems deliver precise hydraulic flow on demand — consuming power only when actuators are in motion. At the high cycle rates inherent in 28-cavity production, this demand-responsive architecture delivers meaningful energy cost savings compared to fixed-speed hydraulic pump systems operating at equivalent output.
15KW Nano Far-Infrared Heating
The screw and barrel assembly uses a 15KW nano far-infrared energy-saving heating ring. The higher heating capacity reflects the machine’s large-volume barrel assembly and ensures uniform melt temperature across the full 680g injection volume — critical for consistent preform quality across all 28 dual-row cavity positions.
Single-Machine Dual-Line Economics
Running 28 cavities on one machine eliminates the capital cost, utility connections, floor space, and operator headcount that would be required for a second ISBM machine. The dual-row configuration also simplifies quality management — one machine, one process parameter set, one operator, one maintenance schedule.
Italian-Import Hydraulic Circuit
All hydraulic lines use Italian-sourced high-pressure tubing providing superior burst pressure ratings and long-term vibration fatigue resistance. In a machine operating at the high cycle rates of 28-cavity production, circuit integrity and consistent hydraulic response are non-negotiable — Italian-grade tubing delivers both.

High-Volume Small-Bottle Application Industries
The EP-HGY250-V4-B dual-row configuration is purpose-built for manufacturers where small-container production volume is the primary production economics driver:
Pharmaceutical Small-Dose Bottles
High-volume production of 50ml–250ml pharmaceutical tablet, capsule, and liquid medicine bottles at 12–20 cavities per cycle. The dual-row process ensures consistent preform thermal conditioning across all cavity positions — critical for the dimensional tolerances required by pharmaceutical tamper-evident and child-resistant closure systems.
Cosmetic Sample & Travel Vials
Travel-size and sample-format cosmetic bottles in 50ml–100ml sizes at 20–28 cavities per cycle. The dual-row ISBM process produces high-clarity PETG vials with the optical quality demanded by prestige cosmetic brands — at production rates that make sample programme economics viable.
️ Eye Drop & Ophthalmic Bottles
Small-volume 5ml–30ml eye drop and nasal spray containers at high cavities per cycle. The zero-contact ISBM production cycle is inherently suited to ophthalmic packaging cleanliness requirements. The 28-cavity maximum enables the production volumes required for cost-competitive ophthalmic packaging supply.
Travel Personal Care Containers
Travel-size shampoo, conditioner, lotion, and shower gel bottles in 50ml–100ml at maximum dual-row cavity counts. FMCG brands producing hotel amenity collections and travel retail packaging benefit from the dual-row machine’s ability to achieve competitive unit economics at these small volumes.

Frequently Asked Questions — EP-HGY250-V4-B
How does the dual-row configuration achieve higher cavity counts without increasing cycle time?
In a dual-row ISBM machine, both rows of cavities are processed simultaneously at every station — injection, temperature conditioning, blow molding, and take-out all operate on both rows in the same cycle. The turntable rotates once per cycle regardless of whether there are 8 or 28 total cavities across the two rows. The result is that cavity count doubles with no change in cycle time — directly doubling production output from the same machine operating at the same cycle rate.
How does cavity-to-cavity consistency compare between single-row and dual-row machines?
Maintaining consistent preform weight, temperature, and wall thickness across 28 positions in a dual-row configuration requires careful hot runner manifold design and thermal conditioning system layout. Ever Power’s dual-row mould engineering addresses this through balanced manifold design and independent thermal conditioning pin circuits for each cavity position. First-article inspection across all 28 positions is included in every dual-row mould qualification to verify inter-cavity dimensional consistency.
What is the minimum bottle size the EP-HGY250-V4-B can produce in dual-row mode?
The minimum producible bottle in the dual-row configuration is a 25mm body diameter, 15mm neck diameter container with a maximum volume of 50ml and a maximum weight of 15g (28-cavity configuration). This represents the practical lower bound for the ISBM process in terms of preform size and blow-up ratio. For containers smaller than this specification, alternative packaging processes such as injection blow molding (IBM) without the stretch step may be more appropriate — contact our applications team to discuss.
Can the EP-HGY250-V4-B run in single-row mode if needed?
Yes. The machine can be configured with single-row moulds when the full 28-cavity output is not required — for instance, during product development, small trial runs, or when running larger bottle sizes that do not fit the dual-row cavity layout. Single-row operation uses the same machine platform with a single-row mould installed — no machine reconfiguration is required beyond the mould change itself.
What compressed air and utility requirements does this machine have?
The EP-HGY250-V4-B requires: Power supply 370–400V / 3-phase (82.7KW total connected load); High-pressure compressed air at 2.0–3.5 MPa from a dedicated high-pressure compressor (sold separately); Cooling water at 0.4–0.6 MPa inlet pressure, temperature below 25°C; Machine oil cooler water at 0.3–0.4 MPa, temperature 20–25°C; Floor loading capacity minimum 2T/m² beneath the machine footprint area. Detailed installation drawings and utility specification sheets are provided upon order confirmation.
