How the EP-HGY500-V3 Works
Three-Station One-Step Process Flow
One-step injection stretch blow molding is a highly efficient plastic container molding process. The core principle is to first produce a preform by injection molding, then stretch the preform axially using a stretch rod, and finally expand it radially with high-pressure air so that it closely fits the mold cavity and cools into the finished container shape. The EP-HGY500-V3 completes all three steps continuously in the same equipment without intermediate handling, producing high-precision hollow plastic products such as baby bottles, water bottles, medicine bottles, craft bottles, cosmetic bottles, and special-shaped containers made of PET, PETG, PP, PPSU, PC, Tritan, PS, ABS, or PLA.
Moldagem por Injeção
PET resin is heated and plasticized into melt, which is injected into the preform mold by the hydraulic screw. The melt cools around the core rod to form a transparent preform with a precisely formed threaded neck finish. Wall thickness distribution and crystallinity are controlled through mold design.
Moldagem por sopro e estiramento
The hot preform is stretched axially by a stretch rod while high-pressure air simultaneously expands it radially within the blow mold cavity. This biaxial molecular orientation dramatically improves the container's mechanical strength, transparency, and barrier performance. The bottom tail is also precisely trimmed.
Ejection & Take-Out
The finished bottle is cooled by circulating water for 5–20 seconds, then the mold opens and the container is automatically ejected. Bottles exit dimensionally stable and ready for quality inspection, leak testing, and downstream filling operations. The automated take-out system minimizes handling damage.
Why One-Step ISBM?
The Smart Choice for Modern Packaging Production
Menor consumo de energia
The one-step process eliminates the need for preform reheating entirely. Because the preform moves directly from injection to stretch-blowing while still at its optimal processing temperature, manufacturers can achieve up to 40% energy savings compared to conventional two-step systems. There is no separate infrared oven, no preform storage, and no energy wasted on reheating cooled preforms.
Maior consistência da garrafa
With injection, stretching, and blowing all happening in one machine, the preform never leaves a controlled environment. There is no handling between stages, no external contamination, and no temperature loss from transportation. This integration delivers superior dimensional repeatability, more uniform wall thickness, and fewer defects per production run.
Produção flexível
The EP-HGY500-V3 produces containers with superior neck finish accuracy and optical surface quality. It supports rapid changeovers between different bottle sizes and materials, making it ideal for manufacturers serving multiple product lines. The machine handles everything from tiny 5 ml cosmetic vials to large 6,000 ml containers with equal proficiency.
Tipos de máquinas de moldagem por injeção e sopro
Understanding the ISBM Machine Landscape
When evaluating injection stretch blow molding machine manufacturers, it is helpful to understand the different machine configurations available and where each one excels. The primary classifications are based on station count, drive type, and process architecture.
Three-Station Machines
Three-station ISBM machines like the EP-HGY500-V3 integrate injection, stretch-blow, and ejection on a single rotary turntable. They provide an excellent balance of cost-efficiency and production flexibility, and are well suited for medium-volume production of cosmetics, pharmaceuticals, and specialty containers. The compact footprint makes them popular among manufacturers with limited floor space.
Four-Station Machines
Four-station configurations add a dedicated conditioning station between injection and blow molding. This extra thermal conditioning step allows for more precise temperature profiling of the preform, resulting in superior wall thickness control. Four-station machines, such as the EP-HGY650-V4, are typically chosen for applications requiring the tightest dimensional tolerances or for processing challenging materials.
Six-Station Machines
Six-station ISBM machines incorporate additional conditioning and process stations for the highest possible throughput and quality. They are engineered for high-volume, continuous production runs and are frequently used in large-scale beverage and consumer goods manufacturing where output speed is the primary consideration.
Beyond station count, ISBM machines are also categorized by their drive system. Hydraulic machines offer high clamping force at a competitive price point. Servo-hydraulic machines combine hydraulic power with servo precision for improved energy efficiency. Fully electric machines eliminate hydraulic systems altogether, providing the cleanest and most energy-efficient operation, though at a higher initial cost. As a leading isbm machine manufacturer, Ever-Power offers models across multiple configurations to match specific production requirements and budget constraints.
Whether you are looking for an isbm machine for sale to start a new production line or searching for a reliable isbm mold injection machines supplier to expand existing capacity, the EP-HGY500-V3 represents the most practical choice for factories currently running or transitioning from Aoki-500 equipment.

Packaging Manager — United States
We switched from our aging Aoki-500 units to the EP-HGY500-V3 about eight months ago. The transition was smoother than we anticipated because our existing Aoki molds fitted the new machine without any modification. Cycle times dropped by roughly 18%, and our rejection rate has decreased. The servo injection system gives noticeably more consistent wall thickness than our old hydraulic setup. The energy bill is definitely lower, though I would recommend having your electrician verify power requirements before installation.

As someone who has operated Aoki machines for over fifteen years, I had high expectations for the EP-HGY500-V3 as a replacement. The mold compatibility claim turned out to be accurate — we installed our existing Aoki molds and started production within two days. The build quality of the machine is solid, and the Yaskawa servo motors provide smooth and accurate movement. The screw design produces a very uniform melt quality, which shows in the final bottle clarity. It is a practical alternative for shops looking to replace older Aoki units without investing in entirely new tooling.
Carlos Silva
Operations Manager — Brazil
We use the EP-HGY500-V3 for cosmetic bottle production at our plant near São Paulo. The machine produces containers with good surface finish and consistent neck threading, which is critical for our pump and spray closure compatibility requirements. Energy consumption is lower than our previous two-step setup by about 30 percent. The servo clamping system maintains even pressure distribution, resulting in fewer mold-related defects. One thing I would note is that the initial calibration took some patience, but once dialed in, the machine runs very steadily.
Piotr Radziwiłł
Plant Engineer — Poland
We acquired the EP-HGY500-V3 to produce Tritan baby feeding bottles and PC sport bottles for the European market. The machine handles both materials without issues, and the changeover between them is manageable within a half-day including mold swap. The Parker and YUKEN hydraulic components are familiar to our maintenance team, which simplifies upkeep. Production quality has been consistent across three shifts of daily operation over the past six months. The machine's footprint is smaller than our previous equipment, which freed up valuable floor space for an additional downstream packaging line.
