Patented Design
Blow Molding Screw
Our injection screw features a patented design optimized for PET and multi-material processing. The proprietary geometry improves plasticization uniformity and reduces material degradation, heated by a nano-far-infrared energy-saving ring.
How It Works: 4-Station Process Flow
Injection → Conditioning → Stretch Blow → Ejection
The EP-HGY150-V4 uses a continuous 4-station rotary mechanism. Raw resin enters as pellets at Station 1 and exits as a finished, precision-molded bottle at Station 4 — all within a single machine, with no intermediate handling or reheating required.
Injection Molding
PET resin is heated, plasticized, and injected into the preform mold via the patented screw system. The melt cools around the core rod to form a transparent preform with precise threaded neck finish. Wall thickness distribution and crystallinity are controlled by mold design.
Temperature Conditioning
The core rod carrying the hot preform rotates to Station 2. The bottom tail is cut by a servo-driven cutter. The preform is precisely re-conditioned — body kept hot for optimal stretching while the neck is cooled to maintain thread accuracy.
Stretch Blow Molding
A stretch rod extends axially while high-pressure air (2.0–3.5 MPa) expands the preform radially into the blow mold cavity. Biaxial molecular orientation significantly improves bottle strength, transparency, and barrier properties.
Ejection
The finished bottle is cooled by circulating water for 5–20 seconds until dimensionally stable. The mold opens and the container is ejected automatically. The cycle time ranges from 10 to 30 seconds depending on bottle specifications.
Why Choose One-Step ISBM?
The Smart Alternative to Two-Step Processes
Lower Energy Consumption
No preform reheating required. The one-step process retains the injection heat, which translates to up to 40% energy savings compared to conventional two-step blow molding systems. For high-volume operations, this reduction has a significant impact on per-unit cost.
Higher Bottle Consistency
Injection, stretching, and blow molding all happen in one machine. With no preform storage, handling, or reheating, the process eliminates variables that cause dimensional variation. The result: every bottle meets the same tight tolerances from the first cycle to the last.
Flexible Production
Superior neck finish and appearance quality make the one-step process ideal for premium cosmetic, pharmaceutical, and specialty containers. Quick mold changes allow small-batch and multi-SKU production runs with minimal downtime.
Types of Injection Stretch Blow Molding Machines
Understanding ISBM Machine Categories
Injection stretch blow molding machines are classified based on their production process and design configuration. Understanding these categories helps buyers select the right equipment for their specific production volumes, bottle types, and quality requirements.
One-Step (Single-Stage) ISBM
In a one-step system, the entire process — from raw material injection to finished bottle — occurs on a single machine without any intermediate storage of preforms. This approach provides the best neck finish quality, minimal material waste, and the highest dimensional accuracy. It is the preferred choice for cosmetic bottles, pharmaceutical containers, baby bottles, and specialty packaging. The EP-HGY150-V4 belongs to this category, and Ever-Power is a trusted ISBM machine manufacturer in this segment.
Two-Step (Two-Stage) ISBM
Two-step systems separate the injection and blow molding processes into two distinct machines. Preforms are first produced by an injection molding machine, stored, and later reheated in a separate blow molding unit. While this method suits very high-volume water and beverage bottle production, it requires more energy for reheating and typically produces less precise neck finishes compared to one-step systems.
Rotary vs. Linear Configuration
Within both one-step and two-step categories, machines can further be divided by their station layout. Rotary machines (like the EP-HGY150-V4 with its 4-station turntable) offer compact footprints and continuous operation. Linear machines arrange stations in a line, which may be preferred for specific mold configurations. Ever-Power also serves as an ISBM mold injection machines supplier, providing both molds and complete equipment solutions.
Material-Specific Variants
Some ISBM machines are optimized for specific resins. PET and PETG machines dominate the market, but specialized variants exist for PP (polypropylene), PC (polycarbonate), Tritan, PPSU, and even PLA (bio-based plastic). The EP-HGY150-V4 handles a wide range of these materials, making it one of the most versatile machines in its class.
