1. What Is a One-Step ISBM Machine (EP-HGYS280-V6)?
The EP-HGYS280-V6 is a 6-station one-step ISBM machine (Injection Stretch Blow Molding) built for medium-to-high-volume PET and PETG bottle production. It consolidates injection, temperature conditioning, stretch-blow, and ejection into a single continuous rotary cycle — no preform storage, no reheat stage, no second machine.
Six stations work in parallel: while one position is injecting a preform, the next two condition it to the precise stretch temperature, the fourth applies stretch-blow at up to 3.5 MPa, and the fifth ejects the finished container. This overlap means the machine can produce up to 10 finished bottles per cycle — containers ranging from a 20 ml single-serve vial to a 2,500 ml wide-neck jar — using screw diameters from 40 mm to 60 mm and a theoretical injection volume of up to 480 cm³.
It is engineered specifically for B2B buyers in beverage filling, pharmaceutical packaging, personal care, and food-grade chemical industries that need mid-to-large batch flexibility, consistent neck-finish accuracy, and a production footprint that fits a standard factory bay (5,900 × 2,600 × 3,200 mm).

Why Manufacturers Choose the EP-HGYS280-V6 One-Step ISBM Machine
Six stations, one machine, zero preform logistics. Here is what that means in hard numbers:
Component Quality
Brand-Name Internals, Not Budget Substitutes
The turntable runs on a Japan Yaskawa servo motor with a TSUNTIEN precision reducer. High-pressure air control uses Parker valves (USA). Hydraulic circuit uses YUKEN valves (Taiwan). Oil tubing is imported from Italy. These aren’t marketing checkboxes — they directly affect cycle consistency and mean time between failures.
Energy Efficiency
10 kW Nano Far-Infrared Heating Saves ~28% vs. Quartz
The dual-rod heating system uses a nano far-infrared energy-saving ring rated at 10 kW — roughly 28% more efficient than a conventional quartz heater at the same heat transfer task. Servo-driven hydraulics idle at under 9 kW vs. a fixed-pump system’s constant ~18 kW draw. Total installed power: 53.2 kW.
Output Range
20 ml Vials to 2,500 ml Jars — Same Machine
Cavity configuration runs from 1 to 10 pieces per cycle. A single mould change covers everything from a 20 ml eye-drop vial (neck ø12 mm) to a 2,500 ml wide-mouth jar (neck ø85 mm). For contract packagers managing 10+ SKUs a year, this breadth replaces what would otherwise be 2–3 separate machines.
Process Control
Integrated Temperature Control — Accurate to ±1 °C
An integrated box control system manages preform conditioning temperature station by station. Accuracy of ±1 °C across all six positions eliminates the wall-thickness variation that causes base-cracking failures in carbonated beverage bottles — a critical issue when filling lines run at 400+ bottles/min.
Hygiene & Compliance
Zero Preform Transfer = Zero Contamination Window
Because PET resin goes straight from hopper to finished bottle with no intermediate storage or conveying, there is no contamination exposure window. Pharmaceutical and food-grade customers consistently cite this as the deciding factor when auditing one-step ISBM machines against two-step alternatives.
Blow Molding System
Dual Blow System: Hydraulic or Servo Motor Damping
The blow station uses either a hydraulic cylinder or a dual servo motor mold damping system with high-pressure compensation — selectable based on the bottle geometry and wall-thickness requirement. This dual-path design gives operators precise control over stretch ratio across the container’s full height.

Where the EP-HGYS280-V6 ISBM Machine Gets Deployed
This 6-station one-step ISBM machine is sized for annual outputs of 2,000,000 – 15,000,000 bottles — too large for a compact 4-station system, yet the bottle-geometry variety makes a fixed high-speed RSBM line impractical. The segments below represent where customers are currently running this model:
🥤
Still & Carbonated Beverages
250 ml – 2,500 ml PET water and CSD bottles. The ±1 °C conditioning accuracy and 2.0–3.5 MPa blow pressure deliver the base-thickness consistency needed to pass drop-test requirements at 4× fill pressure.
💊
Pharmaceutical & Supplement Bottles
20 ml – 400 ml PETG vials and capsule bottles with neck ø12–38 mm. The closed-loop injection process supports ISO Class 7 cleanroom production. Zero preform handling eliminates a common GMP non-conformance point.
🧴
Personal Care & Cosmetics
30 ml – 900 ml containers for shampoo, body lotion, and serum. Custom oval and asymmetric geometries are achievable through tooling design. The 50 mm minimum screw diameter handles high-viscosity PETG at a stable melt.
🫙
Food Jars & Condiment Bottles
Wide-neck PET jars (ø85 mm) up to 2,500 ml for peanut butter, honey, sauces, and preserved foods. Optional heat-set mould upgrade supports hot-fill at up to 88 °C for pasteurised products.
🧹
Household & Industrial Chemicals
1,000 ml – 2,500 ml PET containers for detergent, disinfectant, and agrochemical liquids. The high blow clamping force (200 kN/side) handles the thicker walls required for chemical resistance ratings.
🏭
OEM Converters & Contract Packagers
Sub-2-hour mould changeover and recipe-save HMI make running 12+ client SKUs per month economically viable. Converters report average batch ROI breakeven at 18–22 months when replacing outsourced preform supply with in-house ISBM production.

Frequently Asked Questions —EP-HGYS280-V6 One-Step ISBM Machine
Q1: Why choose a 6-station one step ISBM machine over 4-station models? than a 4-station model for high-output PET bottle production? ▾
A: The additional two stations on the EP-HGYS280-V6 are used for an extended temperature-conditioning phase. This longer dwell time allows the machine to process higher-IV PET resins (0.80–0.84 dL/g) and thicker preforms without compromising crystallinity or wall-thickness uniformity — something that limits many 4-station one-step ISBM machines to narrower resin windows. In practice, the 6-station layout supports up to 10 bottles per cycle vs. the 4-station’s typical 4–6, translating to a 40–60% output increase on comparable bottle formats. For annual volumes above 2 million bottles, the per-unit economics of the 6-station one-step injection stretch blow molding machine are meaningfully better.
Q2:Can this one-step ISBM machine produce PETG bottles, and what are the key processing differences vs. PET? ▾
A: Yes — the EP-HGYS280-V6 is validated for both PET and PETG. PETG has a lower glass transition temperature (Tg ~80 °C vs. PET ~76–80 °C) but requires tighter conditioning control due to its narrower processing window. The integrated box control system with ±1 °C temperature accuracy across all six stations handles this without additional hardware. PETG is increasingly specified in pharmaceutical and cosmetic packaging because of its superior clarity, impact resistance, and compatibility with solvent-based inks — so having a single one-step ISBM machine that runs both resins is a significant operational advantage for converters managing multi-sector client portfolios.
Q3: What utility connections and floor loading does the EP-HGYS280-V6 PET bottle manufacturing machine require?▾
A: Four utility feeds are required: (1) Power: 370–400 V / 3-phase / 50 Hz; 53.2 kW total installed load; dedicated breaker ≥100 A recommended. (2) Low-pressure air: ≥0.8 MPa at ≥4 m³/min for pneumatic circuits. (3) High-pressure air: 2.0–3.5 MPa at ≥1.5 m³/min for blow; a dedicated high-pressure compressor is required (not included). (4) Cooling water: two circuits — machine cooling at 0.4–0.6 MPa and oil cooler at 0.3–0.4 MPa; water temperature 20–25 °C; closed-loop chiller strongly recommended above 26 °C ambient. Floor loading: minimum 14 kN/m² for the machine’s 14 T dry weight. A CAD utility layout is provided within 5 business days of order confirmation.
Q4: How long does mould changeover take on this injection stretch blow molding machine, and is operator training included?▾
A:A trained 2-person crew completes a mould changeover in 90–120 minutes, including purging the injection unit, swapping the blow mould and core rods, and reloading the saved process recipe from the HMI. The PLC stores unlimited named recipes, so re-running a previously validated mould typically takes under 8 minutes. Every machine ships with 3 days of on-site operator training by a factory-certified engineer. Training covers daily startup, process parameter adjustment, fault diagnosis, and preventive maintenance intervals. A training manual in English (and additional languages on request) is included.
Q5: What is the one-step ISBM machine price range for the EP-HGYS280-V6, and what is included in the purchase?▾
A: Pricing for the EP-HGYS280-V6 depends on the screw diameter configuration (40 / 50 / 55 / 60 mm), power supply standard (50 Hz vs. 60 Hz), and any optional add-ons (in-line crystallising dryer, hot-fill heat-set mould, rPET-grade barrel). Contact us for a formal quotation — typical response time is 1 business day. Every machine purchase includes: ex-factory testing video before shipment, on-site commissioning by a factory engineer, 3-day operator training, 12-month parts warranty, a 2,000-hour wear-item spare parts kit, and post-commissioning technical support via video call. Moulds are quoted separately. Average customer ROI breakeven: 18–24 months based on replacing third-party preform supply at 2-shift, 5-day weekly operation.
7. Customer Reviews
Stefan V.
Head of Production Engineering — Pharmaceutical Packaging, Netherlands
We benchmarked three one-step ISBM machine suppliers before selecting the EP-HGYS280-V6. The deciding factor was the Yaskawa servo turntable combined with the YUKEN hydraulic valve — both components we knew from our other lines. After 14 months of continuous operation at 2 shifts per day, our actual electricity consumption is 51 kW·h per 1,000 bottles for 500 ml containers, against the 58 kW·h our previous two-step line consumed. Neck-finish rejection at our capping station is consistently below 0.12%. We ordered a second unit eight months into production.
Derek O.
Director of Operations — Contract Beverage Packer, Georgia, USA
My CFO asked me why we needed a machine the size of a school bus that weighs as much as a herd of elephants. I showed him the electricity bill comparison. He stopped asking questions. We run 4 million bottles a year on this thing — water, juice, and a hot-sauce line for a regional brand — and the only time it’s stopped since installation was because one of my guys accidentally saved “test mould Thursday” as a production recipe and nobody noticed until Friday morning. That’s a people problem, not a machine problem. Parker valves, Yaskawa drive, no drama.
