EP-HGY650-V4 Large-Capacity 4-Station One-Step Injection Stretch Blow Molding Machine Overview
O EP-HGY650-V4 is the flagship model in the EP-HGY range — a heavy-duty large-capacity 4-station one-step injection stretch blow molding machine purpose-built for producing the largest PET and PETG containers manufactured by the ISBM process. With the ability to produce containers up to 20 litres in volume, this machine serves the water cooler barrel, large-format food container, and industrial packaging markets with ISBM process quality advantages that alternative blow molding technologies cannot match.
The defining specifications of the EP-HGY650-V4 are its 400KN injection clamping force, 400KN blowing clamping force, and a class-leading 1070mm upper mold stroke — enabling the large-format preforms required for 20L container production to be injection-molded, conditioned, and blow-expanded within a single continuous automated cycle. The machine weighs 28 tonnes and occupies a footprint of 6100×2600mm — a testament to the structural rigidity required to handle 400KN clamping forces on containers of this scale.
The ISBM process advantage is particularly significant at large container volumes: unlike extrusion blow molding (EBM), the one-step ISBM process produces biaxially oriented PET containers with dramatically superior oxygen barrier properties, wall thickness uniformity, and optical clarity — making the EP-HGY650-V4 the technology choice for water cooler and large-format food packaging where material performance matters as much as container size.

Large-Capacity 4-Station Process Architecture
The turntable is driven by a Japan Yaskawa servo motor with a Taiwan TSUNTIEN reducer — providing the high-torque, vibration-controlled indexing required to rotate the machine’s large-diameter turntable carrying heavyweight large-format preforms. YUKEN hydraulic control valves from Taiwan govern the injection and blow clamping systems. Italian-imported hydraulic tubing throughout the 400KN high-pressure circuit ensures the burst pressure integrity and fatigue resistance required for this demanding application. A dedicated 600L oil tank provides the thermal mass to maintain stable hydraulic temperature across extended production runs.
Large-Format ISBM Engineering — EP-HGY650-V4 Differentiators
400KN Injection + 400KN Blow Clamping
Matched 400KN clamping forces at both the injection and blow stations provide the structural rigidity required to contain the high injection pressures and blow pressures associated with large-format preforms and containers. At 20L container size and a projected mold area that is 10× a standard cosmetic bottle, 400KN is the minimum clamping specification for reliable flash-free production.
1070mm Upper Mold Stroke — Series Maximum
The 1070mm upper mold stroke is the longest in the entire EP-HGY series and among the longest available in any commercial ISBM machine. This exceptional stroke travel accommodates the tall preforms required for 20L container production, where the preform height before blow expansion is substantially greater than the finished container’s fill height.
Up to 20L Container Volume
Producing containers up to 20 litres in volume via the ISBM process — including the 18.9L (5-gallon) water cooler barrel format used globally in point-of-use water dispenser systems. The ISBM process produces 20L water cooler barrels with superior optical clarity, wall uniformity, and oxygen barrier versus EBM alternatives.
175+175mm Blow Mold Stroke
The 175+175mm (350mm total) blow mold opening stroke provides ample clearance for the large-diameter blow mold tooling required for 20L containers. A 280mm body diameter bottle in 1-cavity configuration requires significantly more mold opening clearance than smaller containers — this enlarged blow mold stroke ensures collision-free mold operation across the full container size range.
600L Oil Tank — Extended Run Stability
The 600L hydraulic oil tank is the largest in the EP-HGY series. At 400KN clamping forces and high injection pressures, hydraulic heat generation is substantial — a large-volume oil tank maintains thermal stability across multi-hour production runs, ensuring consistent hydraulic response and preventing thermal creep in clamping force.
ISBM vs EBM — Why It Matters at 20L
Large-format EBM containers have inherently non-uniform wall thickness due to the parison extrusion process. ISBM produces biaxially oriented containers with uniform wall distribution, far superior oxygen barrier performance, and dramatically better optical clarity. For water cooler barrels, food containers, and any large-format application where product quality inside the container matters, ISBM is the superior process.

Large-Format Container Applications
The EP-HGY650-V4 serves a distinct set of applications that no other EP-HGY model addresses — large-format containers where ISBM process quality provides a decisive performance advantage over EBM and other container manufacturing processes:
18.9L / 20L Water Cooler Barrels
The 18.9L (5-gallon) PET water cooler barrel is the globally dominant format for point-of-use water dispensers in offices, homes, and public spaces. ISBM-produced water cooler barrels offer superior wall thickness uniformity, clarity, and oxygen barrier compared to EBM barrels — extending shelf life and maintaining water taste purity over the full product lifespan.
Large-Format Food Containers
Food-grade PET containers in 5L–12L sizes for bulk food retail, catering supply, and food service packaging. The ISBM process’s oxygen barrier properties protect food quality during extended shelf periods — a decisive advantage for edible oils, sauces, and liquid food products sold in large-format containers.
Industrial & Chemical Containers
Industrial packaging in 10L–20L formats for cleaning chemicals, agricultural inputs, and industrial liquids. PET’s chemical resistance profile combined with the ISBM process’s wall uniformity and neck finish precision enables high-quality industrial container production that meeting safety and regulatory requirements for hazardous material containment.
Large Beverage & Water Bottles
Large-format beverage containers in 5L–12L sizes for retail water, juice, and beverage distribution. The ISBM process’s biaxial orientation gives large PET beverage containers the stacking strength and column load resistance needed for retail shelf presentation and distribution logistics without additional container wall weight.
Large-Format Mould Engineering
Large-format ISBM moulds for the EP-HGY650-V4 require specialised engineering that differs fundamentally from standard bottle tooling. The injection mould must accommodate preform heights of up to 500mm with wall thicknesses significantly greater than standard containers — requiring careful hot runner design, gate positioning, and cooling channel layout to achieve uniform preform quality across the large shot volume.
Blow mould tooling for large-format containers must withstand 400KN clamping force across the full 280mm mold diameter — requiring mould steel selection, parting line design, and cavity cooling layout that goes beyond standard bottle blow mould practice. Ever Power’s mould engineering team has specific experience in large-format ISBM tooling development, including water cooler barrel moulds and large food container tooling. Full qualification documentation including wall thickness mapping from multiple positions on the large-format container is included with every new mould delivery.

Frequently Asked Questions — EP-HGY650-V4
Why use ISBM instead of EBM for 20L water cooler barrels?
Extrusion blow molding (EBM) is the conventional technology for 20L water cooler barrel production, but it has inherent limitations: EBM produces containers with non-uniform wall thickness (thicker at the pinch seam, thinner mid-body), lower optical clarity due to the parison extrusion process, and inferior oxygen barrier performance versus biaxially oriented PET. The ISBM process produces water cooler barrels with uniform biaxial orientation throughout the container wall — delivering superior clarity, oxygen barrier, stacking strength, and wall uniformity. For premium water brands and retailers who differentiate on container appearance, ISBM-produced barrels command a packaging premium that more than offsets the higher capital cost of the ISBM machine.
What is the cycle time for producing a single 20L water cooler barrel?
Cycle time for 20L water cooler barrel production on the EP-HGY650-V4 depends on wall thickness specification, preform design, and resin grade. Typical cycle times for 18.9L–20L barrel production range from 40 to 70 seconds per cycle in 1-cavity configuration. Optimised preform designs and high-flow PET resins with IV in the 0.80–0.84 dl/g range achieve the shorter end of this range. Our applications team provides a cycle time estimate with ±10% accuracy based on your specific bottle design and wall thickness specification during the project feasibility phase.
What is the maximum container height the EP-HGY650-V4 can produce?
The machine’s 510mm rated bottle height applies to the 1-cavity 20L configuration. The 1070mm upper mold stroke accommodates the preform height required for 510mm finished bottle production. For taller containers, the practical upper limit is determined by the blow-up ratio from preform height to finished container height for the specific container geometry — contact our applications team with your container height and volume specifications for a specific assessment.
Does the EP-HGY650-V4 require a special high-pressure air compressor?
Yes. Like all ISBM machines, the EP-HGY650-V4 requires a dedicated high-pressure air compressor providing 2.0–3.5 MPa blowing air pressure. For 20L container production, the compressor air demand per cycle is substantially higher than for small bottle production — due to the large blow mold internal volume. Our installation team provides a compressor sizing specification based on your cavity count, bottle volume, and target cycle time. Oil-free high-pressure compressors are strongly recommended for food-grade and water container applications.
Can the EP-HGY650-V4 produce containers smaller than 5L?
Yes. The machine supports 1 through 4 cavities, with the smaller cavity configurations capable of producing containers down to approximately 5L minimum in the 4-cavity layout (180mm diameter, up to 7L). For containers below 5L, the machine’s clamping force, mold stroke, and shot volume are over-specified — a smaller EP-HGY model would be more economical. The EP-HGY650-V4 is specifically designed and economically justified for large-format container production in the 5L–20L range.
Produce the Largest ISBM Containers in the Industry
The EP-HGY650-V4 delivers 20L ISBM container production with 400KN clamping, a 1070mm upper mold stroke, and the superior biaxial orientation quality that EBM cannot match. Whether you are producing water cooler barrels, large-format food containers, or industrial packaging — our engineering team will assess your container specifications and production targets to confirm machine suitability.
