Injection Stretch Blow Moulding Machine HGY250-V4 | Heavy-Duty 4-Station ISBM Technology
Maximize production precision with the HGY250-V4, a heavy-duty 4-station injection stretch blow moulding machine. Engineered for the Korean cosmetic and pharmaceutical sectors, it features a massive 300KN clamping force and direct ASB-70DPH mold compatibility. This “One Step” solution integrates injection, conditioning, stretching, and ejection to produce crystal-clear PET/PC containers from 30ml to 2.5L with 40% energy savings.
Product Overview: Precision Engineering for the Korean Market
In the high-stakes world of cosmetic and pharmaceutical packaging, optical clarity and dimensional precision are non-negotiable. The HGY250-V4 injection stretch blow moulding machine is Ever-Power's flagship solution, engineered specifically to bridge the gap between legacy tooling assets and modern production efficiency. Unlike standard two-step systems that separate the preform and blowing stages, this machine executes the entire resin-to-bottle journey in a single, compact 4-station unit. By maintaining the preform's intrinsic heat profile through the "One Step" process, we ensure superior aesthetic quality—free from the scuffs and haze often associated with reheating cold preforms. This makes it the ideal choice for heavy-wall cream jars, high-gloss lotion bottles, and intricate medical vials demanded by top-tier brands in Seoul and Gyeonggi-do.
A critical strategic advantage of the HGY250-V4 is its direct compatibility with ASB-70DPH molds. We understand that many manufacturers have invested heavily in high-quality Japanese tooling. Our machine features identical platen layouts, tie-bar spacing, and ejection strokes, allowing you to seamlessly transfer your existing molds to our platform without expensive modifications. Equipped with a massive 300KN Injection Clamping Force and a reinforced 200KN Blowing Clamping Force, the HGY250-V4 effortlessly handles high-cavitation setups (up to 14 cavities for small vials) and challenging resins like PC and Tritan. The integrated servo-driven hydraulic system reduces energy consumption by approximately 40% compared to traditional fixed-displacement pump machines, significantly lowering operational costs per unit.
Technical Specifications & Performance Data
Reliability in an ISBM machine is defined by its ability to maintain consistent pressure and temperature over millions of cycles. The HGY250-V4 utilizes a 16-ton vibration-dampening chassis to ensure stability.

The 4-Station Process: How Does Injection Stretch Blow Moulding Work?
The secret to the HGY250-V4's superior quality lies in its integrated 4-station process. Unlike two-step systems that require reheating cold preforms, our machine maintains the material's latent heat. Here is the injection stretch blow moulding machine process step by step:
1. Injection Station
Molten resin (PET/PC) is injected into the preform mold cavity around a core rod. The 300KN clamping force ensures that the neck finish—the most critical part for sealing—is molded with micron-level precision, absolutely free of flash.
2. Conditioning Station
The core rod rotates to the conditioning station. Here, the preform's temperature is equalized. We can selectively heat or cool specific zones, ensuring that square or oval bottles stretch evenly without thinning at the corners.
3. Stretch & Blow Station
A stretch rod physically extends the preform lengthwise while high-pressure air expands it radially. This biaxial orientation aligns the polymer molecules, significantly enhancing the bottle's drop impact resistance and barrier properties.
4. Ejection Station
The mold opens, and stripper plates remove the finished bottles from the core rods. The bottles are oriented and placed onto a conveyor belt automatically. The entire process is touchless, meeting strict hygiene standards.
Technology Deep Dive: ISBM vs. IBM vs. Two-Step
Choosing the right machinery depends on understanding the difference between injection stretch blow molding and injection blow molding (IBM). While standard IBM is sufficient for small, non-pressurized pill bottles, it lacks the "stretch" component. Without physical stretching, the bottle lacks biaxial strength and cannot be made with thin, lightweight walls.
Furthermore, when comparing the HGY250-V4's "One Step" process to traditional "Two Step" (Reheat) systems, the advantages of injection stretch blow moulding become clear. Two-step systems require preforms to be tumbled, stored, and transported, leading to inevitable surface scuffing. Our one-step machine eliminates this handling entirely, delivering glass-like surfaces essential for luxury branding. Additionally, by utilizing the residual heat from injection, the HGY250-V4 reduces overall energy consumption by approximately 40%.
- ✔ Precision Neck Finish: Injection molded necks guarantee 100% leak-proof cap seals.
- ✔ Material Versatility: Capable of processing PET, RPET, PP, PC, PS, and Tritan on the same machine.
- ✔ Compact Footprint: Integrates injection and blowing in one frame, saving valuable factory floor space.
Essential Matching Parts & Accessories
A high-performance injection stretch blow moulding line requires a synchronized ecosystem. To ensure your HGY250-V4 operates at peak efficiency, Ever-Power supplies perfectly matched ancillary equipment designed to withstand the rigors of 24/7 industrial production.
Oil-Free Air Compressor
The blowing phase demands high-pressure air (3.0-3.5 MPa) that is absolutely free of contaminants. We recommend our Oil-Free High-Pressure Compressor to prevent any oil mist from entering the molding cavity, ensuring compliance with FDA and medical standards.
Chains, Gears & Transmission Shafts
The HGY250-V4 utilizes a precision indexing table driven by a heavy-duty transmission shaft and high-tensile chains and gears. While our machines are built to last, keeping a spare set of these specific drive components ensures that your production line faces minimal downtime during scheduled maintenance intervals.
Industrial Applications: Precision Across Sectors
The HGY250-V4 is not just a general-purpose machine; it is a specialized platform engineered for industries requiring high optical clarity, complex geometries, and strict hygiene standards. While two-step machines dominate the water bottle market, our injection stretch blow moulding machine is the preferred choice for high-value packaging where the "One Step" process eliminates surface defects and ensures neck precision.
💡 Engineer's Insight: "One of the hidden benefits of this 4-station ISBM machine is its flexibility. For contract manufacturers (CMO), switching from a 150ml cosmetic toner bottle to a 250ml pharmaceutical syrup bottle involves a quick mold change and parameter selection, without the need to re-calibrate a separate preform injection line. This agility is crucial for 'Just-in-Time' production strategies."
