Máquina de moldeo por soplado y estirado por inyección de un solo paso EP-HGY200-V4 ISBM (reemplazo de la máquina Aoki 250)
The EP-HGY200-V4 is a one-step injection stretch blow molding machine engineered by Ever-Power as a direct replacement for the Aoki 250 series. It integrates injection molding, temperature conditioning, stretch blow molding, and ejection into a single continuous cycle — converting raw PET resin into finished bottles without preform reheating or intermediate handling. Equipped with a servo-hydraulic system delivering 300 KN injection clamping force and a 50 mm standard screw (with 40/55/60 mm options), the machine supports up to 12-cavity production across materials including PET, PETG, PC, PP, PPSU, and Tritan. Fully compatible with existing ASB and AOKI molds, it offers up to 40% energy savings over two-step processes, ±5% wall thickness uniformity, and cycle times as short as 10 seconds — making it ideal for cosmetic, pharmaceutical, food-grade, and baby care bottle manufacturing.
About the EP-HGY200-V4 ISBM Machine
Advanced single stage injection stretch blow molding machine engineered for global production environments
The EP-HGY200-V4 is a next-generation one-step injection stretch blow molding machine developed by Ever-Power with over 20 years of accumulated expertise in precision container manufacturing. This machine integrates injection molding, stretching, blow molding, and ejection into a single continuous process — from raw PET resin to finished bottles without any intermediate handling or preform reheating.
Designed as a direct replacement of Aoki injection stretch blow molding machines — particularly the Aoki 250 series — the EP-HGY200-V4 offers comparable output performance and superior mold compatibility at a significantly lower total cost of ownership. One of the most important engineering advantages is full compatibility with Japanese ASB machine molds, which means existing customers of ASB and AOKI can migrate to the EP-HGY200-V4 without investing in new tooling. This backward compatibility has made the machine especially popular among manufacturers who want to upgrade their production lines without discarding their existing mold inventory.
The machine employs a hydraulic clamping system paired with a hydraulic screw injection unit, delivering 300 KN of injection clamping force — sufficient for high-cavitation molds and dense engineering resins. The standard screw diameter is 50 mm, with options for 40 mm, 55 mm, and 60 mm barrels depending on the application requirements. From baby bottles and pharmaceutical containers to premium cosmetic packaging and wide-mouth food jars, the EP-HGY200-V4 handles a broad spectrum of materials including PET, PETG, PP, PPSU, PC, Tritan, PS, ABS, and PLA.
With a compact footprint of 4800 × 2000 × 3200 mm and a machine weight of just 13 tons, the EP-HGY200-V4 fits into most existing factory layouts with ease. The oil tank volume of 300 L supports stable hydraulic pressure throughout extended production runs, while the 310 g theoretical injection capacity (range: 188–480 cm³) provides flexibility for both small and medium-sized containers. As a leading isbm machine manufacturer, Ever-Power has delivered hundreds of these units to production facilities across Asia, the Middle East, South America, and Europe.

Características y ventajas
Servo-driven precision meets industrial durability
Servo-Driven Injection & Clamping
The EP-HGY200-V4 uses servo motors from Inovance and Yaskawa to control both the injection and clamping systems. This delivers repeatable shot-to-shot accuracy, reduces energy waste during idle strokes, and provides the fine pressure control needed for thin-wall and complex-geometry bottles. Compared to purely hydraulic systems, the servo-hybrid design typically reduces power consumption by 30–40%.
Control estable del espesor de la pared
Achieving uniform wall thickness is critical for pharmaceutical and cosmetic containers where material integrity directly affects product shelf life. The servo injection system maintains ±5% wall thickness uniformity across the entire bottle body — including corners and transition zones — ensuring that every container meets stringent quality benchmarks without excessive manual sampling.
ASB & AOKI Mold Compatibility
Ever-Power manufactures molds in-house using S136 stainless steel, and more importantly, our machines are engineered to accept molds designed for ASB and AOKI platforms. This means your existing mold investments carry over directly — no modifications, no adapters, no compromises. It is the most practical upgrade path for factories currently running Japanese equipment.
Eco-Friendly & Energy Efficient
By eliminating the preform reheating stage entirely, the one-step process saves up to 40% of energy compared to two-step blow molding lines. Combined with the servo motor's demand-based power delivery, the EP-HGY200-V4 offers one of the lowest energy-per-bottle figures in its class. Material utilization exceeds 95%, minimizing plastic waste from flash, runners, and rejected parts.
Consistent & Repeatable Production
The multi-axis control system enables precise coordination of all stations — injection, temperature conditioning, stretch blow, and ejection — running in parallel on a rotary platform. Cycle times range from 10 to 30 seconds depending on bottle size and cavity count. The closed-loop feedback on temperature, pressure, and stroke position ensures that the 10,000th bottle in a run is indistinguishable from the first.
Highly Precise Engineering
The stretch blow system achieves speeds up to 400 mm/s with positional accuracy of ±0.1 mm. Zoned heating with non-contact temperature measurement provides ±1°C control across the preform body. These specifications are on par with the most demanding food-grade and pharmaceutical packaging standards, making the EP-HGY200-V4 suitable for regulated industries worldwide.

🔧 Patented Blow Molding Screw Design
Our injection screw features a proprietary geometry protected by national patents. The specialized compression ratio and flight design ensure thorough plasticization of PET and other engineering resins at lower barrel temperatures, reducing material degradation and improving optical clarity of the finished bottles. This patented screw is one of the technical differentiators that set Ever-Power apart from other injection stretch blow molding machine manufacturers in the market.
How the One-Step ISBM Process Works
Four integrated stations on a single rotary platform — from resin to finished bottle in one continuous cycle
Moldeo por inyección
PET resin is heated and plasticized by the injection screw, then injected into the preform mold. The melt cools around the core rod to form a transparent preform with a fully finished threaded neck. Wall thickness distribution is controlled through mold design and injection parameters.
Temperature Conditioning & Tail Cutting
The core rod carrying the hot preform rotates to the second station. A servo-driven cutter removes the injection gate (tail). The preform body is then precisely reheated — keeping the body hot while cooling the neck — to achieve optimal stretch temperature and maintain thread accuracy.
Moldeo por soplado y estirado
A mechanical stretch rod extends axially to elongate the preform, while high-pressure air expands it radially into the blow mold cavity. This biaxial orientation improves molecular alignment, increasing the bottle's strength, transparency, and gas-barrier properties. Stretch speed reaches 400 mm/s with ±0.1 mm precision.
Ejection & Take-Out
The finished bottle is cooled by circulating water for 5–20 seconds, then the mold opens and the container is ejected. All four stations operate simultaneously on the rotary table, which means a new bottle is completed with every rotation cycle — enabling cycle times as short as 10 seconds.
Why One-Step ISBM?
The single-stage advantage over two-step and extrusion blow molding
Menor consumo de energía
Because the preform proceeds directly from injection to stretching and blowing while still hot, there is no energy-intensive reheating step. This translates to up to 40% energy savings compared to two-step processes. For high-volume operations running 24/7, this energy reduction has a tangible effect on annual operating costs and carbon footprint.
Mayor consistencia en la botella
Injection, stretching, and blowing happen in one continuous machine cycle with no transfer or handling between stages. This eliminates the variability introduced by preform storage, transport, and re-orientation. The result is a tighter dimensional tolerance on neck finish, body wall, and base — essential for automated filling lines that demand uniform containers.
Producción flexible
The one-step process excels in short-to-medium production runs where preform inventory management is impractical. Quick mold changes allow switching between bottle designs in under an hour. The integrated neck finish injection ensures superior thread accuracy and sealing quality — critical for child-resistant caps and tamper-evident closures.
Types of Injection Stretch Blow Molding Machine
Understanding the different ISBM configurations available in the market
One-Step (Single-Stage) ISBM Machines
One-step machines — such as the EP-HGY200-V4 — complete the entire process from raw resin to finished bottle in a single integrated machine. The preform is injection molded and immediately stretched and blown while still warm. This method is ideal for premium containers such as cosmetic jars, pharmaceutical bottles, baby bottles, and specialty food packaging where surface quality, neck precision, and dimensional consistency are paramount. One-step machines offer superior neck finish accuracy and are better suited for complex shapes, wide-mouth containers, and small-to-medium batch production. They handle diverse materials including PET, PC, PETG, PP, Tritan, and PPSU.
Two-Step (Two-Stage) ISBM Machines
In two-step systems, preforms are injection molded on a separate machine, stored, and later reheated and blown on a second machine. This approach is cost-effective for very high-volume, standard-shape PET bottles — such as water, soft drink, and commodity beverage containers — where the preform can be mass-produced and distributed to blow molding lines near the filling facility. However, the reheating step consumes additional energy and introduces more process variability, making two-step machines less suitable for applications that demand tight tolerances or premium surface quality.
Rotary vs. Linear ISBM Machines
Within the one-step category, machines can be either rotary or linear. Rotary designs — like the EP-HGY200-V4 — use a rotating platform where all four stations (injection, conditioning, blowing, ejection) operate simultaneously on different preforms. This maximizes throughput per footprint. Linear machines process preforms along a straight path, which can simplify maintenance access but typically at the cost of speed and floor space efficiency. For high-output production, rotary machines are the preferred configuration among most injection stretch blow molding machine manufacturers.
Servo-Hydraulic Hybrid Machines
Modern ISBM machines — including our EP-HGY200-V4 — increasingly adopt servo-hydraulic hybrid designs. In these machines, servo motors handle the precision movements (injection metering, stretch rod positioning, clamping engagement) while hydraulic circuits provide the raw force needed for high-tonnage clamping and injection. This hybrid approach combines the energy efficiency and positional accuracy of electric servo systems with the force density of hydraulics, offering an excellent balance for mid-range to heavy-duty applications.
Lo que dicen nuestros clientes
Feedback from production facilities across the globe
Mohammed R.
Production Director — Saudi Arabia
"We switched from an older AOKI line to the EP-HGY200-V4 about eight months ago. The mold transition was straightforward since the machine accepted our existing tooling without modification. Energy consumption dropped noticeably on our daily meters — we estimate roughly 35% savings versus the old setup. The wall thickness consistency has been within spec for our pharmaceutical containers, and the servo system responds faster during startup. Our maintenance team adapted to the control interface within two weeks of commissioning."
Lucia S.
Plant Manager — Brazil
"We produce PET cosmetic bottles for several local and international brands, and the surface finish quality from the EP-HGY200-V4 has been consistently good. The neck threads are sharp and uniform, which our filling line operators appreciate because it reduces cap rejection rates. We run the machine on 6-cavity molds most of the time and the output meets our current demand. The remote monitoring feature helped during the initial setup phase when Ever-Power's engineers guided us through some parameter adjustments remotely."
Thanapong N.
Technical Manager — Thailand
"We had been using ASB machines for our baby bottle production and were looking for a more cost-effective alternative that could use our existing molds. The EP-HGY200-V4 was the most practical option we evaluated. The mold fit was confirmed during the trial run, and we have been operating with the same 4-cavity mold for PC baby bottles since installation. The bottles pass our internal burst pressure and drop tests consistently. The machine runs reliably on two shifts per day, and spare parts lead time from Ever-Power has been reasonable so far."
James K.
Operations Manager — Nigeria
"We purchased the EP-HGY200-V4 for producing wide-mouth food jars in PET and PETG. The machine handles mold changes faster than our previous equipment, which is important because we make several different jar sizes for various food brands. The Yuken hydraulic valves have held up well in our operating conditions — we run at ambient temperatures above 35°C much of the year. Ever-Power sent a technician for the initial installation and provided training for our team. The documentation was clear enough for our operators to reference during daily runs."
Anna V.
Purchasing Manager — Poland
"Our company needed to expand production of small PET medicine bottles for a pharmaceutical client. The EP-HGY200-V4 was recommended to us by another manufacturer in our industry network. After visiting Ever-Power's factory and running trial productions with our bottle design, we decided to proceed. The 8-cavity mold configuration gives us the volume we need. The machine's cycle time aligns with what was quoted — around 14 seconds for our 50 ml bottles. We have been satisfied with the overall build quality and the responsiveness of their after-sales team."
Rajesh G.
Factory Owner — India
"We operate three EP-HGY200-V4 units across two factory locations in Gujarat. The primary application is personal care bottles — shampoo, lotion, and hand wash containers in PET and PETG. The machines have been in operation for over a year now, and the servo injection system has maintained consistent shot weight throughout. We compared with other isbm mold injection machines supplier options before deciding, and the combination of ASB mold compatibility, competitive pricing, and Ever-Power's willingness to customize mold configurations for our specific bottle designs was the deciding factor."
