The Right ISBM Machine for Your Bottle, Your Industry
Whether you produce luxury cosmetic containers, pharmaceutical bottles, or high-volume beverage packaging — each application demands a specific combination of precision, throughput, and material expertise. We match the machine to your requirements.
One Technology, Four Distinct Worlds of Packaging
One-step injection stretch blow molding (ISBM) produces bottles with unmatched clarity, dimensional accuracy, and material efficiency. But every industry comes with its own specifications: cosmetics demand flawless surface aesthetics, pharmaceuticals require contamination-free production, and food packaging needs high-speed output at controlled cost.
Rather than offering a one-size-fits-all product list, we analyze your specific application — bottle geometry, material properties, production volume, and regulatory environment — then recommend the HGY series configuration that delivers the best performance per dollar invested.

How One-Step ISBM Works
The core principle: injection molding creates the preform, a stretch rod provides axial orientation, and high-pressure air delivers radial blow expansion — all completed in four synchronized stations within one machine.
Injection Molding
PREFORMPET pellets are heated and plasticized into a uniform melt, then injected via the screw unit into a preform mold cavity surrounding a precision core rod. The mold closes and the melt cools to form a transparent preform with a fully-formed threaded neck finish. Wall thickness distribution and crystallinity are pre-controlled through mold geometry at this stage — establishing the foundation for consistent stretch-blow performance downstream.
Tail Trimming & Temperature Conditioning
REHEATThe core rod rotates the hot preform into the second station. A servo-driven trimming mechanism first removes the gate vestige (injection point) from the preform base, ensuring a clean bottom surface. The preform then enters a conditioning sleeve equipped with zoned heating rings for precise, non-uniform thermal profiling — the body is reheated to optimal stretch temperature while the neck zone remains cool to preserve the integrity of the threaded finish.
Stretch Blow Molding
FORMINGThe blow mold closes around the conditioned preform. The blow core descends to mechanically stretch the preform axially, while high-pressure air is simultaneously injected to inflate it radially, pressing the material against the mold cavity wall. This biaxial orientation aligns the PET molecular chains in both longitudinal and transverse directions, dramatically improving the finished container's transparency, tensile strength, gas barrier properties, and top-load compression resistance.
Cooling & Ejection
FINISHED PRODUCTThe formed container remains in the mold while chilled water circulates through internal cooling channels, rapidly setting the final shape (typical cooling time: 5–20 seconds depending on wall thickness and material). Once dimensionally stable, the mold opens and the finished bottle is automatically ejected onto a conveyor system for quality inspection and downstream packing.

الأسئلة الشائعة
Which ISBM machine is best for cosmetic bottle production?
For cosmetic packaging, four-station and six-station ISBM machines are recommended. Four-station machines (such as the HGY60 and HGY90 series) excel at thick-wall, high-gloss containers up to 500 ml, while six-station machines offer additional cooling time for complex geometries and premium surface finishes using PET, PETG, or PC materials.
Can ISBM machines produce pharmaceutical-grade bottles?
Yes. One-step ISBM machines are ideal for pharmaceutical packaging because the integrated injection-stretch-blow process eliminates preform handling and contamination risk. Full servo-driven systems ensure zero hydraulic oil contamination, making them compatible with ISO Class 8 clean room environments. Common materials include PET, PP, and HDPE.
What is the production capacity difference between three-station and six-station machines?
Three-station machines typically achieve cycle times of 10–14 seconds and are optimized for simple bottle geometries at lower investment cost. Six-station machines reduce cycle times to 6–10 seconds by adding dedicated cooling and conditioning stations, which significantly increases output per hour — making them the preferred choice for high-volume beverage and food packaging production.
What materials are compatible with one-step ISBM blow molding?
One-step ISBM machines support a wide range of thermoplastic materials, including PET, PETG, PP, PC, Tritan (BPA-free), PCTG, PLA, PS, SAN, and ABS. Material selection depends on your industry requirements — for example, PET and PETG for cosmetic clarity, PP and HDPE for pharmaceutical chemical resistance, and Tritan for BPA-free baby care bottles.
How does one-step ISBM compare to two-step blow molding for packaging quality?
One-step ISBM completes injection, stretch, and blow molding in a single machine cycle, retaining the preform’s residual heat to achieve superior molecular orientation. This produces bottles with better optical clarity, more uniform wall thickness, and tighter dimensional tolerances than two-step systems, which require reheating the preform and introduce additional variability. One-step is especially preferred for small-to-medium volume precision packaging in cosmetics, pharma, and baby care.
