Description
EP-HGYS280-V6 6-Station Twin-Screw One-Step Injection Stretch Blow Molding Machine Overview
The EP-HGYS280-V6 is the most technically sophisticated machine in the standard EP-HGY product family — a 6-station one-step injection stretch blow molding machine equipped with a twin-screw dual-injection-unit configuration. By adding two additional dedicated process stations to the standard 4-station layout, the EP-HGYS280-V6 separates the temperature conditioning and stabilisation functions into independent dedicated stations — giving the preform’s thermal state significantly more time and control precision before it reaches the blow station.
This extended conditioning capability is the defining performance advantage of the 6-station architecture: containers that require the most demanding wall thickness uniformity specifications — including asymmetric profiles, wide-diameter large-volume containers, and thin-wall high-clarity applications — benefit directly from the additional thermal stabilisation time that only a 6-station ISBM machine provides.
The twin-screw dual-injection-unit design means two independent screws and barrels share the injection function — providing greater combined shot capacity, redundant plastication capability, and the flexibility to process different material lots or colours across the two injection units. Supporting up to 10 cavities and containers up to 2,500ml, the EP-HGYS280-V6 serves premium cosmetic, pharmaceutical, food, and speciality container applications.

6-Station Process Architecture — Extended Conditioning Advantage
The 6-station rotary turntable is driven by a Japan Yaskawa servo motor with a Taiwan TSUNTIEN reducer. YUKEN hydraulic pressure control valves (Taiwan) manage the injection and blow clamping systems. Italian-imported hydraulic tubing ensures circuit integrity throughout. The two additional process stations between injection and blow molding provide approximately 50% more preform conditioning time per cycle compared to a 4-station machine at equivalent cycle rate — enabling superior thermal equilibration across the preform wall before blow expansion begins.
Why 6 Stations? The Technical Case for Extended Conditioning
Extended Preform Thermal Conditioning
Two dedicated conditioning stations between injection and blow molding provide 50% more thermal equilibration time per cycle. This extended conditioning is critical for containers with demanding wall thickness uniformity requirements — particularly wide-diameter, asymmetric, and thick-walled specialty containers where even minor preform thermal gradients cause visible wall thickness variation.
Twin-Screw Dual Injection Unit
Two independent screws and barrels share the plastication and injection function. This dual-unit architecture provides greater combined shot capacity, maintains production continuity if one unit requires maintenance, and offers the flexibility to process different material formulations if production requirements change.
Widest Container Size Range
Supporting 1 through 10 cavities with containers from 20ml miniatures to 2,500ml large-format bottles and bottle diameters from 20mm to 120mm, the 6-station platform covers the broadest container size range of any machine in the EP-HGY lineup — making it the most versatile ISBM platform for multi-SKU production facilities.
2-Set Servo Pump System
Two servo pump systems deliver precise demand-responsive hydraulic control across all six stations. The reduced number of servo pumps versus 4-station machines reflects the 6-station machine’s more distributed hydraulic load profile — each pump serves clearly defined station groups, simplifying maintenance and diagnostics.
Twin-Screw Nano Far-Infrared Heating
Both screw and barrel assemblies use nano far-infrared energy-saving heating rings rated at 10KW total — providing uniform melt temperature across both injection units. The far-infrared heating technology ensures consistent melt quality even when the two screws are processing slightly different resin lots, minimising colour or viscosity variation between injection cycles.
14-Tonne Production-Grade Platform
At 14 tonnes and a footprint of 5900×2600×3200mm, the EP-HGYS280-V6 is built for permanent installation in dedicated bottle production facilities. Its robust construction handles continuous multi-shift operation with the structural rigidity needed to maintain dimensional consistency across thousands of production hours.

Premium Application Industries for 6-Station ISBM
The EP-HGYS280-V6’s extended conditioning architecture is specified by manufacturers for whom standard 4-station ISBM machines cannot meet wall thickness uniformity or container appearance requirements:
Premium Cosmetics — Highest Clarity Standards
Ultra-high-clarity PETG cosmetic bottles where even sub-millimetre wall thickness variation is visible to consumers. The 6-station conditioning advantage ensures the preform reaches thermal equilibrium before blow expansion — producing optically uniform walls that conventional 4-station machines cannot reliably achieve.
Specialty & Complex-Geometry Containers
Asymmetric, multi-faceted, and complex-profile bottles for artisanal, craft, and luxury brand packaging. The extended preform conditioning time on the 6-station platform gives the preform’s molecular structure time to stabilise before blow expansion — enabling more consistent reproduction of complex geometries.
Large-Format Wide-Mouth Containers
Wide-mouth food, beverage, and storage containers in 1,500ml to 2,500ml sizes where the larger preform diameter requires longer thermal conditioning time for uniform radial temperature distribution before blow expansion. The 6-station machine’s extended conditioning is especially advantageous for these large preforms.
Multi-Material R&D and Pilot Production
The twin-screw dual-injection-unit architecture makes the EP-HGYS280-V6 ideal for R&D operations requiring rapid material switching or processing multiple resin formulations. Pilot production runs for new bottle designs benefit from the 6-station machine’s superior process control and the ability to run small cavity counts at full process quality.

Customer Case Studies — EP-HGYS280-V6
France — Luxury Perfume & Cosmetics
Luxury Cosmetics | Faceted 150ml PETG perfume caps and cosmetic containers, 2-cavity
“Our bottles have eight defined facets that must be optically uniform — any wall thickness variation shows immediately under retail lighting. We trialled several 4-station ISBM machines before specifying the EP-HGYS280-V6. The 6-station conditioning time eliminated the residual thermal gradient we were seeing in 4-station output. Every bottle now passes our polarised light inspection at first-piece.”
★★★★★
Switzerland — Pharmaceutical R&D Facility
Pharmaceutical R&D | Multi-material pilot production, 1–4 cavity development runs
“The twin-screw dual-injection-unit allows us to switch between PET and PETG grades without full barrel changeover — we simply redirect which unit is active. For a pharmaceutical R&D facility running 12–15 bottle development projects per year, this flexibility reduces material changeover time by over 60%. The 6-station conditioning also means our development prototypes have the same process quality as production output.”
★★★★★
Italy — Artisanal Food Packaging
Food & Craft | Asymmetric olive oil bottles and vinegar containers, 2–4 cavity
“Our bottle designs are central to our brand identity — complex asymmetric profiles that differentiate our products at shelf. The 6-station conditioning gave us the wall uniformity on asymmetric profiles that our 4-station ISBM simply could not achieve. Our rejection rate on asymmetric bottles dropped from 8% to under 1%.”
★★★★★
Germany — Specialty Healthcare Packaging
Healthcare | Wide-mouth 1,500ml healthcare product containers, 2-cavity
“Wide-mouth large-format containers are notoriously difficult to condition uniformly in a 4-station machine because of the large preform diameter. The EP-HGYS280-V6’s two conditioning stations gave our large preform the time it needed. We went from consistently failing our wall thickness specification on 4-station machines to passing on the first production run on the 6-station machine.”

Frequently Asked Questions — EP-HGYS280-V6
What is the practical production advantage of 6 stations versus 4 stations?
The two additional stations in the 6-station layout provide dedicated time for preform temperature conditioning and stabilisation — approximately 50% more conditioning time per cycle at equivalent turntable speeds. For most standard bottle geometries, a 4-station machine provides adequate conditioning time. The 6-station advantage is most significant for: containers with wall thickness uniformity specifications tighter than ±0.1mm; asymmetric or complex-geometry bottles; wide-diameter large-format preforms; and PETG containers requiring the highest optical clarity.
How does the twin-screw dual-injection-unit work in practice?
The two screws operate in coordination — both plasticate material simultaneously and inject together into the injection mould. This shared injection action provides greater combined shot capacity than a single screw of the same diameter while maintaining compact machine dimensions. The dual-unit architecture also provides operational resilience: if one screw requires maintenance, the machine can in some configurations continue limited production on the single remaining unit while repairs are made.
Is the EP-HGYS280-V6 compatible with standard 4-station ISBM moulds?
No. The 6-station machine requires a dedicated 6-station mould set — the additional conditioning station tooling positions are additional mechanical interfaces not present in 4-station moulds. However, Ever Power can develop 6-station mould sets that produce bottles currently running in your 4-station moulds — maintaining bottle geometry and dimensional specifications while upgrading to 6-station process quality. Share your existing bottle drawings with our team to discuss the tooling conversion.
What bottle geometries benefit most from the 6-station conditioning advantage?
The greatest benefits are seen with: (1) Wide-diameter bottles above 80mm body diameter where radial thermal gradient in the preform is highest; (2) Asymmetric profiles with unequal wall mass distribution; (3) High-clarity PETG containers where thermal non-uniformity causes optical haze; (4) Thick-wall containers above 3mm average wall thickness; (5) Containers with complex shoulder geometry requiring precise biaxial stretch ratio control. For round, symmetric bottles with standard wall thickness, a 4-station machine typically provides equivalent output quality.
How does the EP-HGYS280-V6 compare to the EP-HGY150-V4-EV in production precision?
The EP-HGY150-V4-EV achieves precision through full servo motion control — 10 servo systems eliminating mechanical variability across all axes. The EP-HGYS280-V6 achieves precision through extended process time — additional conditioning stations reducing thermal gradient at the blow station. The two approaches address different root causes of quality variation: motion precision versus thermal uniformity. For the most demanding applications, some manufacturers specify both the 6-station platform and full servo control — see our engineering team for custom configuration options.
