Product Overview: Redefining Heavy-Duty Production
In the exacting world of industrial polymer processing, specifically within the competitive South Korean and East Asian manufacturing sectors, precision and stability are paramount. The HGY650-V4 stands as the flagship of Ever-Power’s V4 series, meticulously engineered to serve as a high-capacity injection stretch blow moulding machine. Unlike standard lightweight equipment, the HGY650-V4 is built on a reinforced 18-ton chassis designed to eliminate vibration during high-speed cycles. This stability is critical when processing high-viscosity engineering plastics like Polycarbonate (PC) for water bottles or Tritan for infant care products, where even microscopic deviations can lead to rejection.

The machine’s core strength lies in its specialized 4-station rotary indexing system, which seamlessly integrates Injection, Conditioning, Stretch-Blowing, and Ejection into a single, continuous process. This "One Step" methodology preserves the intrinsic heat profile of the preform, ensuring optimal biaxial orientation without the energy-intensive reheating required by two-step systems. With a verified 650KN injection clamping force, the HGY650-V4 provides the immense locking pressure needed to prevent "mold breathing," ensuring zero flash on parting lines—a non-negotiable standard for premium cosmetic jars and pharmaceutical packaging.

Expert Insight: The 4-Station ISBM Process Step by Step
To fully appreciate the HGY650-V4, it is essential to understand how does injection stretch blow moulding work within its 4-station architecture. Unlike simpler systems, our 4-station design offers granular control over the thermal profile of the plastic, which is the key to defect-free molding.
1. Injection Station
Molten PET or PC resin is injected into the cavity to form the preform. The 650KN clamping force ensures that the neck finish is molded to precise tolerances. This high pressure is crucial for preventing flash on the parting lines, a common issue in lower-tonnage machines.
2. Conditioning Station
The preform is transferred to a conditioning pot. Here, the temperature is homogenized—the skin is cooled to form a tough outer layer while the core remains malleable. This "Conditioning" step is the secret to uniform wall thickness in non-round or heavy bottles.
3. Stretch & Blow
A stretch rod extends the preform axially, aligning the molecular structure. Simultaneously, high-pressure air expands it radially. This biaxial orientation imparts exceptional drop-impact strength and optical clarity to the final container.
4. Ejection
The finished bottle is stripped from the lip mold and automatically conveyed out. The process is completely touchless, ensuring the hygiene required for pharmaceutical and food-grade applications, meeting GMP standards.
Technical Comparison: ISBM vs. IBM
A frequent question from our clients involves the difference between injection stretch blow molding and injection blow molding. While both utilize an injection-molded preform, the distinction lies in the "Stretch" phase. Standard Injection Blow Molding (IBM) relies solely on air pressure to expand the plastic, which limits the container's height and mechanical strength.
Traditional Injection Blow Molding (IBM)
- Process: Only blows air radially (no vertical stretching).
- Limitation: Resulting bottles have thicker walls, are heavier, and are more brittle.
- Application: Mostly limited to small, short pharmaceutical bottles (HDPE/LDPE).
Injection Stretch Blow Moulding (ISBM)
- Process: Uses a rod to physically stretch the plastic vertically before blowing.
- Advantage: Aligns polymer chains for thinner walls with significantly higher burst strength.
- Versatility: Capable of producing tall bottles (up to 280mm+) and wide-mouth jars with glass-like clarity.
The advantages of injection stretch blow moulding on the HGY650-V4 include a 15-20% reduction in resin usage due to lightweighting capabilities, superior barrier properties against oxygen and moisture, and an impeccable surface finish free from scuff marks common in two-step reheat processes.
Essential Matching Peripherals
A high-performance machine requires a reliable ecosystem. To ensure the HGY650-V4 operates at peak efficiency, Ever-Power supplies a comprehensive range of matched auxiliary equipment. These components are selected to handle the specific flow rates and pressures of the HGY650 series, ensuring a turnkey solution for your factory.
Oil-Free Air Compressor
The blowing phase demands 30-35 bar of pressure. We recommend our specialized oil-free screw compressors, which ensure that the air entering the mold is certified Class 0 contaminant-free, preserving the clarity of PET/PC and meeting FDA standards.
Transmission Components
The accuracy of the rotary table depends on the integrity of the drive system. We supply heavy-duty chains and precision-ground gears as part of our spare parts package, ensuring smooth indexing and 0.01mm positioning accuracy over years of operation.

Frequently Asked Questions (FAQ)
The 650KN injection force prevents the mold from "breathing" or opening slightly during the high-pressure injection phase. This is critical for maintaining precise neck dimensions and preventing flash on the parting line, especially when molding large surface area containers.
Yes, the plasticizing unit is robust enough to handle high percentages of rPET flakes. We offer specialized bimetallic screws and barrels designed to resist the abrasive nature of recycled materials while ensuring proper mixing and clarity.
We recommend a daily check of the auto-lubrication system and weekly inspection of air filters. A full hydraulic oil analysis should be performed every 6 months, with a complete oil change annually (approx. 5,000 hours) to ensure system longevity.
We have extensive experience exporting to major Korean ports like Busan and Incheon. The 18-ton machine is modularly disassembled, vacuum-packed to prevent corrosion, and secured on Flat Rack or Open Top containers for safe transit.
Yes, the Inovance/Mirle control system supports multiple languages. We can pre-load a Korean interface alongside English to ensure your operators can navigate the system efficiently and safely.
Absolutely. The HGY650-V4 is specifically designed for "heavy-duty" applications, including wide neck finishes up to 140mm. The stable clamping ensures the neck remains perfectly round for automated capping lines.
Depending on the preform thickness and cooling efficiency, cycle times typically range between 15 to 25 seconds. The 4-station concurrent processing significantly reduces dead time compared to shuttle machines.
Yes, we provide comprehensive training at our factory free of charge. We can also dispatch senior engineers to your facility in Korea for installation, commissioning, and on-site staff training (travel costs apply).
We offer a standard 12-month warranty on the machine and all major components (Servo Motors, PLC, Hydraulic Pumps). We also provide lifetime remote technical support and software updates.
We strongly encourage it. Seeing the HGY650-V4 in action is the best way to understand its build quality. Alternatively, we can arrange a live video demonstration producing a product similar to yours.
Customer Success Stories
"We switched to the HGY650-V4 for our premium ginseng cream jars. The clarity of the heavy-wall PETG is outstanding—indistinguishable from glass but much lighter. The 400KN clamp force ensures we have zero flash on the neck, which was a constant headache with our old machines."
Song Hye-jin, Production Manager, Gyeonggi-do (Late 2024)
"I was worried about running PC material for our 18.9L water bottles, but the Ever-Power screw design handles the heat perfectly. No black specks, no burning. Shipping to Busan was fast, and the local parts availability is a big plus for our maintenance team."
Kim Min-su, Factory Lead, Busan (Early 2025)
"The energy savings are real. We replaced two older hydraulic machines with this servo-driven unit, and our electricity bill dropped by 35%. The interface is easy to use, and training my operators took less than a week."
