Maximize production density with the HGY250-V4-B. Featuring advanced “Double-Row” technology, this injection stretch blow moulding machine delivers up to 28 cavities per cycle with a 680g shot capacity. Engineered for high-volume pharmaceutical and cosmetic manufacturing, it ensures superior bottle clarity and neck precision.

Product Overview: The Double-Row Productivity Multiplier

In the competitive landscape of pharmaceutical and cosmetic packaging, output density is the primary driver of profitability. The HGY250-V4-B Injection Stretch Blow Moulding Machine is engineered to shatter the limitations of traditional single-row equipment. By utilizing a revolutionary "Double-Row" (Double Bank) cavity layout, this machine processes two parallel lines of preforms simultaneously. This innovation allows manufacturers to achieve a staggering 28 cavities for small-diameter bottles (up to 25mm), effectively doubling the throughput without expanding the factory footprint. For facilities in South Korea and Asia where space is at a premium, this high-density output is a game-changer.

Injection Stretch Blow Moulding Machine Process Step by Step

To understand how does injection stretch blow moulding work on the HGY250-V4-B, one must look at the integrated rotary system. This "One-Step" process preserves the thermal history of the polymer from pellet to finished bottle, ensuring superior physical properties.

Injection Stretch Blow Moulding Machine HGY250-V4-B

1. Injection Molding

Molten PET is injected into the preform mold cavities. In the "Double-Row" setup, up to 28 preforms are molded at once. The 300KN clamping force ensures that the neck finish is molded to exact tolerances, preventing flash and ensuring a leak-proof seal.

2. Conditioning

The table rotates to the conditioning station. Here, the temperature of the preforms is equalized. This step is critical for the double-row configuration, ensuring that both the inner and outer rows of preforms have the exact same elasticity for stretching.

3. Stretch Blow Molding

Stretch rods extend the preforms axially while high-pressure air (2.0-3.5 MPa) expands them radially. This biaxial orientation aligns the molecules, giving the bottle exceptional impact strength, transparency, and barrier properties.

4. Automated Ejection

Finished bottles are stripped from the core rods and ejected. The process is fully automated and touchless, ensuring the bottles remain sterile and compliant with the strict hygiene standards of pharmaceutical manufacturing.

Difference Between Injection Stretch Blow Molding and Injection Blow Molding

Clients often ask about the difference between injection stretch blow molding and injection blow molding (IBM). While both produce scrap-free bottles, the addition of the "Stretch" rod in ISBM fundamentally alters the container's properties.

Feature Injection Stretch Blow Moulding (ISBM) Injection Blow Molding (IBM)
Mechanism Vertical Stretch Rod + Air Pressure Air Pressure Only (No Stretch Rod)
Container Strength High (Biaxial Orientation) Low (Radial Orientation only)
Wall Thickness Thin, lightweight, uniform Thicker, heavier
Ideal Material PET, PETG, PC (Crystal Clear) PE, PP, HDPE (Opaque/Soft)

Essential Matching Parts for HGY250-V4-B

Ever-Power (HZPT) is a leader in industrial transmission and machinery. To ensure the HGY250-V4-B operates at maximum efficiency, we supply the complete ecosystem of matching components.

Oil-Free Air Compressor

The blowing phase demands clean, high-pressure air (3.0-3.5 MPa). Our oil-free compressors ensure no contaminants enter the sterile bottle interior, complying with ISO cleanroom standards.

Chains and Gears

Reliable rotary indexing depends on high-tensile transmission chains and precision gears. We use reinforced alloy steel components designed to withstand the torque of rapid start-stop cycles.

Transmission Shafts

To handle the 300KN clamping force, the main drive connects via heavy-duty drive shafts. These are dynamically balanced to minimize vibration, ensuring the longevity of the servo motors.

Industry Applications: Precision for Every Sector

The HGY250-V4-B injection stretch blow moulding machine is a versatile powerhouse. Its unique combination of high clamping force (300KN) and high shot capacity (680g) allows it to bridge the gap between high-volume small bottle production and technical heavy-wall container manufacturing.

Pharmaceutical & Medical

The HGY250-V4-B transforms medical packaging production with its "Double-Row" technology. By running up to 28 cavities simultaneously, it offers the output of two standard machines in a single cleanroom footprint.

  • Eye Drop Vials (5ml-15ml): High-density cavitation ensures massive daily throughput for low-margin consumables.
  • Vaccine Containers: The one-step process prevents human contact, ensuring sterility from pellet to finished vial.
  • Tablet Packers: Precise neck molding guarantees 100% seal integrity for child-resistant caps.

High-End Cosmetics

Aesthetics are paramount. Utilizing the machine's massive 680g shot capacity, manufacturers can produce heavy-wall PET bottles that rival the look and feel of glass without the fragility.

  • Serum Bottles: Thick walls with glass-like clarity, achieved through our scratch-free one-step transfer.
  • Mascara & Lip Gloss: The machine handles high aspect ratios (long, thin containers) with uniform wall thickness.
  • Cream Jars: Flawless surface finish ideal for premium hot-stamping and silk-screening.

Food & Specialty Materials

Adaptability is key. The HGY250-V4-B is compatible with advanced screws for processing high-performance, BPA-free polymers like PPSU, PC, and Tritan alongside standard PET.

  • Baby Feeding Bottles: PPSU/Tritan processing capabilities for high-heat sterilization resistance.
  • Miniature Spirits (50ml): The industry standard for airline liquor bottles, combining light weight with rigidity.
  • Wide-Mouth Jars: Suitable for spices, honey, and dried fruits, replacing heavy glass jars.
