2. Revolutionizing Container Production with Advanced ISBM Technology
Unlike traditional two-step processes that require separate preform reheating, our advanced Injection Stretch Blow Molding Machine's four-station design integrates injection, temperature conditioning, stretch blowing, and ejection into a single, seamless operation. This integration not only significantly reduces energy consumption by utilizing the residual heat from the injection phase but also ensures impeccable bottle clarity and mechanical strength. For manufacturers looking for a replacement of ASB injection molding machine systems or those seeking to upgrade from legacy equipment, the HGYS150-V4 Injection Stretch Blow Molding Machine offers a robust solution. The machine's architecture is built to handle a wide array of materials, including PET, PETG, and PC, providing a versatile platform that adapts to changing market trends. By eliminating the need for preform storage and reheating, we minimize the risk of surface contamination, ensuring that the final output meets the highest hygiene standards required for sensitive applications.
3. The Four-Station Injection Stretch Blow Molding Machine Advantage
The core superiority of the HGYS150-V4Injection Stretch Blow Molding Machine lies in its sophisticated four-station rotary design, a configuration that offers distinct advantages over three-station alternatives, particularly for complex bottle geometries. The cycle begins at the Injection Station, where the raw material (granules of PET, PP, or PC) is melted and injected into a preform cavity. Here, the neck finish is molded to exact tolerances, ensuring leak-proof sealing for the final product. The table then rotates to the Temperature Conditioning Station. This is a critical differentiator; unlike simpler machines, this station allows for the precise adjustment of the preform's temperature profile. By actively managing the heat distribution, we can ensure that the material stretches uniformly, preventing common defects like pearlescence or uneven wall thickness, which is vital when producing high-aspect-ratio containers. Next is the Stretch Blow Molding Station, where the conditioned preform is mechanically stretched by a core rod and simultaneously blown with high-pressure air into the final mold shape. This biaxial orientation aligns the molecules, significantly enhancing the container's barrier properties, impact resistance, and transparency. Finally, the product moves to the Ejection Station, where the finished bottles are automatically removed and oriented for downstream packaging. This fully automated injection stretch blow molding process eliminates human intervention, reducing labor costs and scrap rates while ensuring consistent cycle times. The seamless synchronization between these four stations is orchestrated by a high-performance servo system (optional), which provides smooth rotation and clamping, further reducing energy consumption and cycle time compared to hydraulic-only systems.

In the diverse world of packaging, material flexibility is key to staying competitive. The HGYS150-V4 Injection Stretch Blow Molding Machine is engineered with a versatile plasticizing unit that can expertly handle a variety of thermoplastic resins. While Polyethylene Terephthalate (PET) remains the industry standard for clear, high-strength containers due to its excellent barrier properties against oxygen and carbon dioxide, our Injection Stretch Blow Molding Machine is equally proficient in processing PETG (Glycol-modified PET). PETG is increasingly favored in the high-end cosmetic sector for its glass-like clarity, superior chemical resistance, and ability to be molded into thicker, heavier-walled containers without crystallizing or hazing. Furthermore, the machine settings can be fine-tuned to process Polycarbonate (PC), ideal for durable, heat-resistant applications like baby feeding bottles or reusable sports water bottles. We also support Polypropylene (PP) processing, which offers high clarity options (using specific clarifying agents) and excellent moisture barrier properties. The screw geometry and barrel heating zones are designed to ensure a homogenous melt, preventing degradation of sensitive materials. This adaptability allows manufacturers to switch between product lines—from rigid injection stretch blow molding products like pharmaceutical vials to aesthetic cosmetic jars—without the need for extensive equipment overhaul, making it a true replacement injection stretch blow moulding machine for versatile production needs.
5. Injection Stretch Blow Molding Machine Four-Station HGYS150-V4 Application Scenarios
Pharmaceutical Packaging
Precision is paramount in the medical field. Our machine produces high-grade medicine bottles, eye drop containers, and pill jars. The one-step process ensures a sterile environment as the preform is not exposed to external air before blowing. The precision neck molding guarantees perfect closure fitting, essential for child-resistant caps and maintaining drug potency.
Cosmetics & Personal Care
For premium brands, aesthetics are everything. The HGYS150-V4 excels in creating heavy-wall, glass-like PETG and PET bottles for lotions, serums, and creams. The four-station process allows for complex shapes and varying wall thicknesses that traditional machines cannot achieve, providing a luxury look and feel without the weight and fragility of glass.
Food & Beverage Containers
From wide-mouth jars for peanut butter and condiments to rigid sports water bottles. The machine ensures material safety (BPA-free processing capability) and high clarity. The biaxial stretching enhances the bottle's top-load strength, making them suitable for stacking and transport in the logistics chain.
Baby Feeding Bottles
Safety and durability are non-negotiable for infant products. Utilizing PPSU or PC materials, our machine crafts durable, heat-resistant feeding bottles that can withstand repeated sterilization. The precise neck finish ensures compatibility with standard teats and anti-colic systems, providing peace of mind to parents and manufacturers alike.

"Review on HGYS150-V4 Implementation for Serum Vials"
"We were previously struggling with high rejection rates on our local cosmetic and pharma lines due to neck dimension variability. We decided to integrate the EP-One-step machine to standardize our 60ml and 100ml PET vial production. The difference was immediate. The four-station process allows us to control the preform temperature much better than our old blue injection stretch blow moulding machine. We are running 24/7 now with minimal downtime. The energy savings are real—about 30% less than our previous hydraulic systems. For the Colombian market, where electricity costs can fluctuate, this is a massive advantage. Technical support for the injection stretch blow molding process optimization has been excellent."
