Injection Stretch Blow Moulding Machine Process Step by Step

Injection Moulding

Temperature Conditioning

Stretch & Blow

Cooling & Ejection

Step-by-step industrial manufacturing workflow

1

Injection Moulding

PET resin pellets are plasticized and injected around a core rod, forming a precise threaded-neck preform.

Preform Formation

2

Temperature Conditioning

Zoned heating (body hot, neck cool) reconditions the preform for ideal stretch temperature without reheating.

Thermal Optimization

3

Stretch & Blow

A rod elongates the preform while high-pressure air (±0.05 MPa) blows it into the final container shape.

Biaxial Orientation

4

Cooling & Ejection

Cooling water sets the shape (5-20s). Finished containers are automatically ejected for packing.

Difference Between Injection Stretch Blow Molding and Injection Blow Molding



Fundamentals and Similarities of IBM and ISBM

Both IBM and ISBM start by injecting molten resin (e.g., PET, PP) into a mold to form a threaded preform, ensuring precise wall thickness control. IBM expands via air pressure only; ISBM adds axial stretching for enhanced properties.

Key Differences in Technique and Orientation

Core difference: ISBM includes axial stretching via rod, creating biaxial orientation; IBM uses radial air pressure only, resulting in uniaxial orientation and thicker walls. ISBM offers superior strength, clarity, and uniformity.

Applications, Advantages, and Trade-offs of IBM vs. ISBM

IBM suits HDPE/PP jars for cost-effective food or pharmaceutical packaging, versatile but with lower clarity. ISBM excels in lightweight PET bottles (5-20L) for beverages, providing better barriers and efficiency.

Choosing the right technology for your packaging needs

Injection Blow Molding (IBM)

Relies solely on air pressure to form the container. Best for HDPE/PP jars and complex shapes with handles, but offers lower molecular orientation.

Injection Stretch Blow Molding (ISBM)

Adds mechanical axial stretching for biaxial orientation. Creates thinner, lighter bottles with elite strength and clarity.

Feature	IBM (Standard)	ISBM (High Performance)
Forming Method	Radial blowing only	Axial stretch + Radial blow
Molecular Orientation	Low	High (Biaxial)
Wall Thickness	Thicker, less uniform	Thin, precise, lightweight
Clarity & Gloss	Moderate	Superior (Glass-like)
Best Application	Wide-mouth PP/HDPE jars	PET beverage & Pharma

Note: ISBM is the preferred choice for high-strength carbonated drink packaging.

FAQs

Advantages of Our ISBM

What is an injection stretch blow moulding machine?

An injection stretch blow moulding machine, or ISBM machine, is an advanced one-step equipment that integrates injection moulding, temperature conditioning, axial stretching, radial blowing, and ejection to produce high-quality plastic containers from resins like PET, PP, PETG, and PC, ensuring superior clarity, strength, and efficiency.

How does an injection stretch blow moulding machine work?

It operates through a rotary multi-station process: molten resin forms a preform via injection; the preform is conditioned and stretched axially; high-pressure air expands it radially; and the container cools before ejection, completing cycles in 10–30 seconds with uniform wall thickness (±5% tolerance).

Why choose an ISBM machine from Australia Ever-Power?

Australia Ever-Power offers machines with 18 years of expertise, compatibility with Japanese ASB molds for seamless upgrades, energy savings of 20–30%, and customized solutions for beverage, food, pharmaceutical, and cosmetic packaging, supported by 67 employees and 56 global projects.

Who benefits from using injection stretch blow moulding technology?

Manufacturers in beverage (5 ml–20 L bottles), food packaging (e.g., oil bottles), pharmaceutical (e.g., vials), and daily chemical industries (e.g., shampoo bottles) benefit, as it provides hygienic, lightweight containers with enhanced barrier properties and production efficiency.

When should a company invest in an ISBM machine?

Investment is ideal when scaling high-volume production requiring biaxial orientation for improved tensile strength (over 30% increase), material utilization (95%+), and reduced energy costs, especially for transitioning from traditional two-step methods to automated, one-step processes.

Customer Reviews
