One Step Blow Molding Machine HGY50-V3-EV: Precision 3-Station ISBM Technology for PET Containers

Engineered by Ever-power | 20+ Years of Polymer Processing Expertise

Engineering Overview: Redefining Production Efficiency

The HGY50-V3-EV is not just a machine; it is a strategic asset for manufacturers aiming for the premium segment of the packaging market. This One Step Blow Molding Machine integrates the injection of the preform and the blowing of the bottle into a single, compact unit. This eliminates the reheating phase required in two-step processes, thereby preserving the Intrinsic Viscosity (IV) of the PET and ensuring crystal-clear transparency and superior mechanical strength.

The core advantage of the HGY50-V3-EV lies in its 3-station architecture. Unlike 4-station machines that consume more floor space and energy, our V3 design optimizes the thermal retention of the preform. By utilizing the residual heat from the injection process, we drastically reduce energy consumption while maintaining a cycle time that rivals larger industrial units. It is the ideal ISBM Machine for producing high-quality cosmetic containers, pharmaceutical bottles, and premium beverage packaging where surface finish and dimensional accuracy are non-negotiable.

Core Technology: The One-Step ISBM Principle

The One Step PET Bottle Machine concept revolutionizes production by performing the entire bottle creation lifecycle on a single turntable index. This is crucial for materials like PETG, PC, and PCTG which are sensitive to reheating cycles.

Operational Process Flow

1. Injection Station

Molten resin is injected into the preform mold. The neck is formed to exact dimensions, and the body is cooled to a conditioned temperature suitable for stretching.

2. Conditioning (Thermal)

In our HGY50-V3-EV, temperature homogenization occurs during the transfer. The preform core is kept warm while the skin is cooled, creating the perfect thermal gradient for biaxial orientation.

3. Stretch & Blow Station

A stretch rod mechanically elongates the preform axially, while high-pressure air expands it radially. This biaxial stretching aligns the molecules for maximum strength.

4. Ejection Station

The finished container is stripped from the lip mold and automatically conveyed out. No manual intervention is required, ensuring hygiene.

Strategic Analysis: One-Step vs. Two-Step Systems

Why choose a One Step Injection Blow Molding system over the traditional two-step method? The answer lies in efficiency and quality control.

Comparison Dimension Ever-power One-Step ISBM Traditional Two-Step (Reheat)
Process Flow Resin to Bottle (Direct) Resin -> Preform -> Storage -> Reheat -> Bottle
Energy Efficiency High (Uses residual injection heat) Low (Requires reheating cooled preforms)
Bottle Aesthetics Perfect (No scratches, high gloss) Risk of scratches during preform transport
Space Requirement Compact (One machine) Large (Injection machine + Blow machine + Storage)
Material Flexibility Excellent (PET, PC, PP, PETG, Tritan) Limited (Mostly standard PET)
Scrap Rate Low (Integrated feedback loop) Higher (Start-up losses in two machines)

Core Technology Speed-Read: Why HGY50-V3-EV?


  • Invisible Parting Lines: Our dual-servo clamping with high-pressure compensation ensures that cosmetic bottles have virtually invisible seams, a critical requirement for luxury brands.

  • Energy Dynamics: By integrating the One Step Injection Molding Machine logic, we utilize the “latent heat” of the plastic. You are not paying to heat the plastic twice.

  • Versatility: Whether it’s a specialized 10ml eye-drop vial or a wide-mouth peanut butter jar, the variable stroke and variable cavity capabilities make this machine a universal soldier in your factory.

Engineer’s Corner: Frequently Asked Questions

Can this machine process recycled PET (rPET)?

Yes, the plasticizing screw is specially coated to handle the slightly different melt flow index of rPET. However, the material must be thoroughly dried and dehumidified before processing.

What is the mold changeover time?

For a skilled technician, a complete mold change (Injection + Blow + Lip molds) takes approximately 2 to 3 hours. The quick-change design of the HGY50-V3-EV facilitates this.

Does it require a chiller?

Yes, consistent mold cooling is critical for cycle time and clarity. We recommend a 10HP-15HP chiller depending on your ambient temperature.

How does the 3-station design handle conditioning?

The 3-station design (Injection, Stretch-Blow, Eject) manages conditioning primarily in the injection mold and during the turntable transfer. By precise control of the injection mold cooling time, we deliver the preform to the blow station at the exact orientation temperature.
