Injection Stretch Blow Moulding Machine Process Step by Step

To truly appreciate the engineering behind the HGY150-V4, one must understand the intricacies of how does injection stretch blow moulding work within a 4-station rotary framework. This continuous loop process is the gold standard for high-precision manufacturing, ensuring that the material state is optimized at every millisecond of production.

What is Injection Stretch Blow Moulding?

At its molecular level, injection stretch blow moulding (ISBM) is the art of polymer orientation. Unlike simple extrusion or injection blowing, ISBM relies on processing the plastic material—typically PET or Tritan—within its "thermoelastic" range. The HGY150-V4 is designed to maintain the preform exactly within this temperature window (typically 90°C - 110°C for PET) throughout the transfer from injection to blowing.

The definition of "Stretch" in this context is mechanical. A vertical rod physically forces the preform to elongate. This mechanical action disentangles the polymer chains and aligns them parallel to the bottle's walls. This alignment creates a "chain-link fence" effect at the microscopic level, which is why ISBM bottles are virtually unbreakable under normal drop conditions and possess a glass-like clarity. The HGY150-V4's servo control ensures that the speed of this stretch rod is perfectly synchronized with the air blowing rate, preventing issues like "pearlescence" (whitening due to over-stretching) or "haze" (opacity due to under-stretching).

For manufacturers in the Korean market, where "glass-replacement" plastic packaging is a growing trend, ISBM is the only viable technology. It allows for the production of thick-walled containers that feel like glass but are lightweight and shatterproof. The HGY150-V4 excels in this specific application, offering the ability to mold wall thicknesses up to 3-4mm without the cooling defects common in other machinery.

Investing in capital equipment requires selecting the right process. Clients often ask about the difference between injection stretch blow molding and injection blow molding (IBM). While both processes start with an injected preform, the distinction lies in the molecular restructuring of the material.

Essential Matching Components for HGY150-V4

A high-performance ISBM-masin requires an ecosystem of equally reliable auxiliary components. Ever-Power provides a turnkey solution by supplying matched parts that ensure the HGY150-V4 operates at peak efficiency.

• 1. Oil-Free Air Compressor

  The clarity and detail of the final bottle depend on the quality of the blowing air. We recommend and supply oil-free screw compressors capable of delivering stable 3.0-3.5 MPa pressure. Oil contamination in the air supply is the leading cause of rejection in clear cosmetic bottles. Our matched compressors ensure Class 0 oil-free air, meeting the stringent hygiene standards of the pharmaceutical and food industries.

• 2. Chains and Gears

  The reliability of the 4-station indexing table relies on robust transmission components. While the main indexing is servo-driven, the internal mechanical linkages utilize high-grade roller chains and precision-cut gears. We source these from top-tier suppliers to ensure they can withstand the rapid start-stop torque of the servo motors without elongation or backlash, ensuring millions of cycles of precise alignment.

• 3. Transmission Shaft

  The main transmission shaft is the spine of the machine, coordinating the movement of the clamping unit and the rotary table. Ever-Power utilizes hardened alloy steel shafts that are precision-ground to minimize vibration. A stable transmission shaft is critical for maintaining the 0.01mm positioning accuracy of the preforms, especially when operating at high speeds with multi-cavity molds.
