Patented Blow Molding Screw Design
The injection screw inside the EP-HGY250-V4 features a patented geometry optimized for uniform plasticization of PET and other resins. Heated by nano-far-infrared energy-saving heating rings (10KW), the screw delivers consistent melt quality with lower energy consumption and reduced material degradation. Available in 50mm, 55mm, and 60mm diameters to match your specific production requirements. This proprietary screw design is a key differentiator that sets Ever-Power machines apart from other производители машин для литья под давлением с растяжением и выдувным формованием.
How the EP-HGY250-V4 Works: 4-Station Process Flow
The one-step ISBM process converts raw resin into finished containers in a single integrated cycle. The four stations rotate continuously on a Yaskawa servo-driven turntable, with each cycle overlapping to maximize throughput.
Литье под давлением
PET resin is heated and plasticized by the servo-driven screw (50/55/60mm diameter options), then injected into the preform mold cavity with up to 300KN clamping force and up to 480cm³ injection volume. The melt cools around the core rod, forming a transparent preform with a precision-threaded neck finish. Wall thickness distribution and crystallinity are controlled through mold design and injection parameters.
Temperature Conditioning & Tail Cutting
The core rod carrying the hot preform rotates to the second station via the Yaskawa servo turntable. A servo-driven cutter precisely removes the bottom tail. With a 300mm regulating core stroke and 300mm regulating barrel stroke, the preform body is reheated to the optimal stretch temperature while the neck remains cool, preserving thread accuracy and dimensional integrity.
Выдувное формование с растяжением
The conditioned preform enters the blow mold with 200KN blowing clamping force (single side). A stretch rod extends axially with a blow core stroke of 300mm while high-pressure air (2.0–3.5 MPa) expands the preform radially through a 75+75mm blow mold stroke. This biaxial orientation improves the final container's strength, clarity, and barrier performance significantly.
Ejection
The finished container is cooled by circulating water (0.4–0.6 MPa pressure, machine oil cooler at 20–25°C) for 5–20 seconds depending on material and wall thickness. With a 190mm take-out stroke, the mold opens and the finished bottle is ejected, ready for downstream filling or packaging. The entire cycle typically takes 10–30 seconds per station.
Why Choose One-Step ISBM?
Снижение энергопотребления
The one-step process eliminates preform reheating entirely, which accounts for a significant portion of energy use in two-step systems. With only 82.7KW total power consumption and nano-far-infrared energy-saving heating technology, manufacturers report up to 40% energy savings compared to conventional reheat blow molding lines — translating directly into lower per-unit production costs.
Более высокая стабильность качества бутылок
Because injection, stretching, and blowing happen within the same machine without intermediate handling, the preform temperature profile is always predictable. The 300KN injection clamping force and precise servo control lead to uniform wall thickness, consistent bottle weight, and better optical clarity — especially important for cosmetic and pharmaceutical containers.
Flexible Production & Superior Quality
One-step ISBM delivers exceptional neck finish quality with no gate marks on the bottom. Supporting 2 to 14 cavities and bottle volumes from 30ml to 2500ml, the EP-HGY250-V4 handles short production runs efficiently without stockpiling preforms. It processes a wide range of bottle sizes and materials within a single platform, giving you unmatched production flexibility.
Типы машин для литья под давлением с выдувным формованием.
Understanding the different machine types helps manufacturers select the right equipment for their specific production needs and budget.
One-Step (Single-Stage) ISBM
Injection, conditioning, stretching, blowing, and ejection occur within a single machine. The preform is never fully cooled or removed from the production line. This type — which the EP-HGY250-V4 belongs to — is ideal for premium containers requiring high clarity and precise neck finishes. It is the preferred technology among leading cosmetic, pharmaceutical, and specialty packaging producers worldwide.
Two-Step (Reheat) ISBM
In this system, preforms are produced by a separate injection molding machine, cooled, stored, and then reheated and blown on a different machine. While this type handles very high volumes for standard water and beverage bottles, it requires more equipment, more floor space, and significantly more energy due to the reheating process.
Three-Station vs. Four-Station Rotary
Within the one-step category, machines are further classified by the number of rotary stations. Three-station machines combine conditioning and blow molding into a single station, making them more compact but somewhat less flexible. Four-station machines, like the EP-HGY250-V4, dedicate a separate station to temperature conditioning and tail cutting, resulting in better preform preparation and higher quality bottles.
Hydraulic vs. All-Electric ISBM
Traditional ISBM machines use fully hydraulic drive systems. Modern machines like the EP-HGY250-V4 use a hybrid approach: hydraulic clamping for high-force stability combined with servo-driven injection for precision and energy savings. The blow molding structure adopts hydraulic cylinder or dual servo motor mold clamping with high-pressure compensation. If you are looking for an Продается терминал ISBM that offers this hybrid efficiency, the EP-HGY250-V4 is a strong candidate worth evaluating.
