Description
EP-HGY50-V3-EV Full Servo 3-Station One-Step Injection Stretch Blow Molding Machine
The EP-HGY50-V3-EV is a compact, fully servo-driven one-step injection stretch blow molding machine (ISBM) engineered for high-precision hollow plastic container production. Its 3-station rotary platform seamlessly integrates injection molding, preform tail cutting and heat preservation, stretch blow molding, and bottle take-out in a single continuous automated cycle — eliminating the need for secondary reheating and reducing energy consumption by up to 40% compared to conventional two-step blow molding systems.
Driven by 5 sets of fully servo control systems (Inovance/MiRLE), the EP-HGY50-V3-EV delivers exceptional repeatability and low-noise operation. Its compact footprint (3800×1200×2500 mm) and 3.5-tonne machine weight make it ideal for high-performance ISBM production in limited factory floor space. The machine accommodates PET and PETG materials and supports up to 6 cavities, producing containers from 100 ml to 2,500 ml.
Purpose-built for industries demanding zero human-hand contact throughout production — including GMP pharmaceutical packaging, premium cosmetics, and baby product manufacturing — this 3-station ISBM machine uses imported brand components throughout for long-term reliability.

Production Process Flow
The 3-station rotary turntable is driven by a Japan Yaskawa servo motor paired with a Taiwan TSUNTIEN reducer, ensuring smooth high-torque rotation. Each station operates simultaneously — injection, heat preservation, and blow molding run in parallel — maximising throughput with zero idle time between cycles.
Core Advantages of the EP-HGY50-V3-EV ISBM Machine
Full Servo Precision Control
5 independent servo systems manage every motion axis with microsecond accuracy. The dual servo motor mold clamping system with high-pressure compensation ensures uniform clamping force across all cavities — eliminating flash defects and dimensional variation.
Up to 40% Energy Reduction
By utilising residual heat of the injection-molded preform without secondary reheating, the machine dramatically cuts electricity consumption. Servo drives further reduce idle-state power draw compared to fixed-speed hydraulic systems.
Zero Hand Contact — GMP Ready
The fully enclosed automated production cycle means bottles are never touched by human hands from injection to take-out, making this machine directly compliant with GMP pharmaceutical packaging production standards.
High Material Utilization
The one-step process generates minimal scrap. Molecular orientation through biaxial stretching enhances wall thickness uniformity, improving compression resistance, barrier properties, and optical clarity while using less raw material per bottle.
Compact Footprint, High Output
At just 3800×1200mm floor space the EP-HGY50-V3-EV delivers industrial-grade ISBM performance in a 3.5-tonne package — ideal for manufacturers needing full-scale ISBM quality in limited factory space.
Imported Brand Components
Parker (USA) high-pressure valves, Airtac air cylinders, NSK Japan lead screws, and Yaskawa/Inovance servo motors — global components ensure worldwide parts availability and long-term serviceability.

Bottle Types & Application Industries
The EP-HGY50-V3-EV excels at small-to-medium volume containers with demanding appearance and dimensional tolerances:
Premium Cosmetic Bottles
High-clarity PET and PETG bottles for serums, toners, and lotions. The biaxial stretching process produces outstanding optical transparency and a premium glass-like appearance that commands shelf presence.
Pharmaceutical Medicine Bottles
GMP-compliant production of tablet bottles and eye-drop containers. Zero human contact throughout the cycle ensures sterility and compliance with pharmaceutical packaging standards.
Baby Bottles & Infant Products
PETG baby bottles with superior impact resistance, clarity, and BPA-free material compatibility. The controlled production environment ensures food-safe, contamination-free output.
Specialty & Craft-Shaped Bottles
The one-step process allows complex non-round bottle geometries with asymmetric profiles — enabling decorative craft bottles and artisanal packaging designs that two-step machines cannot reliably reproduce.
Mould Compatibility & Tooling
The EP-HGY50-V3-EV uses a proprietary 3-station mould configuration. Ever Power’s in-house mould engineering team provides custom mould development services — from cavity layout design through trial production and qualification. All moulds are manufactured to tight tolerances ensuring interchangeability across cavity positions.

Frequently Asked Questions — EP-HGY50-V3-EV
What materials can the EP-HGY50-V3-EV process?
The machine is optimised for ANIMAL DE COMPAGNIE and PETG. Standard bottle-grade PET resins with IV 0.76–0.84 dl/g are ideal. PETG grades offer superior clarity for cosmetic and baby product applications. For PP, PC, or Tritan processing, see our full ISBM lineup.
How does the 3-station design differ from 4-station ISBM machines?
A 3-station machine combines preform tail cutting and heat preservation into one station — more compact, lower cost. The 4-station layout provides a dedicated temperature conditioning station for finer preform thermal control, typically benefiting higher-cavity or larger-container applications. For more cavities or larger bottles, consider the EP-HGY150-V4.
What utility connections are required?
Power: 370–400V / 3-phase (45.2KW total load); Compressed air: 2.0–3.5 MPa (independent high-pressure compressor required, sold separately); Cooling water: 0.4–0.6 MPa, inlet temperature below 25°C; Floor loading: minimum 2T/m² beneath the machine footprint.
Can I use existing moulds from other ISBM machine brands?
The EP-HGY50-V3-EV uses a proprietary 3-station mould format, not directly compatible with ASB or AOKI 4-station formats. However, Ever Power can assess your existing mould drawings and advise on adaptation options, or develop new cavity inserts that replicate your bottle geometry. Contact us with your mould drawings for a compatibility evaluation.
What after-sales support is available?
Ever Power maintains full stock of critical wear parts including servo motor units, NSK lead screws, Parker valve components, and Airtac cylinders for rapid dispatch. Remote diagnostic support via video call is available for troubleshooting. On-site installation, commissioning, operator training, and scheduled preventive maintenance visits can be arranged globally.
Ready to Upgrade Your Bottle Production Line?
The EP-HGY50-V3-EV delivers full servo precision, GMP-ready zero-contact production, and up to 40% energy savings in a compact 3.5-tonne package. Our engineering team is ready to match the right ISBM solution to your specific requirements.
