What Is Injection Stretch Blow Moulding?
Injection stretch blow moulding (ISBM) is a one-step process where molten plastic is injected into a preform mould, the preform is conditioned, then stretched and blown into the final bottle shape in the same machine. The stretch aligns polymer molecules biaxially, giving bottles higher strength, better clarity, and superior barrier properties than ordinary injection blow moulding. Korean cosmetic and pharmaceutical companies prefer ISBM because the final containers meet strict hygiene and visual standards without extra handling.
Unlike two-step systems that store and reheat preforms, the HGY50-V3-EV uses the residual heat from injection, cutting energy 40 % and eliminating contamination risks. The result is bottles with wall-thickness variation under 0.05 mm and top-load strength up to 30 % higher.
Injection Stretch Blow Moulding Machine Process Step by Step
Step 1 – InjectionPET resin is plasticized and injected around a core pin to form the preform. Precise temperature control (±1 °C) ensures uniform wall thickness from the start.
Step 2 – Conditioning & Tail CuttingPreform moves to the second station. Excess tail is cut and the body is gently reheated to the ideal stretch temperature while the neck stays cool.
Step 3 – Stretch BlowStretch rod elongates the preform axially; high-pressure air (2.0-3.5 MPa) inflates it radially against the cooled mould. Biaxial orientation creates strong, clear bottles.
Step 4 – EjectionMould opens, finished bottle is removed automatically. Cycle time for a typical 500 ml bottle is 12-18 seconds depending on cavities.
This continuous 3-station rotation keeps the machine running smoothly and minimizes operator intervention – a key reason Korean plants achieve 95 % uptime.
Difference Between Injection Stretch Blow Moulding and Injection Blow Moulding
For manufacturing decision-makers, distinguishing the Ero ruiskupuhallusmuovauksen ja ruiskupuhallusmuovauksen välillä (IBM) is vital. While both processes begin with an injected preform, the mechanical action during the blowing phase dictates the final bottle's properties and suitable applications.
| Feature | ISBM (HGY50-V3-EV) | Traditional IBM |
|---|---|---|
| Orientation | Biaxial – stronger bottles | No stretch – weaker walls |
| Energia | 40 % lower | Higher (reheat required) |
| Pinnan laatu | Flawless | Risk of scuff marks |
| Foot-print | One machine | Separate injection + blower |

IBM
Standard Injection Blow Molding (IBM)
In IBM, the preform is transferred to a blow mold and expanded using air pressure only. There is no physical stretching rod. Consequently, the plastic molecules are not oriented vertically. This process is typically used for small, opaque pharmaceutical bottles (HDPE/LDPE) where clarity and drop-impact strength are less critical.

ISBM
Injection Stretch Blow Moulding (ISBM)
The HGY50-V3-EV uses ISBM. Here, a mechanical rod physically stretches the preform lengthwise before and during air blowing. This imparts "Biaxial Orientation" (alignment in two directions). The result is a bottle with significantly higher tensile strength, improved gas barrier properties, and glass-like transparency. This makes ISBM the only viable choice for high-end cosmetic containers and lightweight water bottles.
Advantages of Injection Stretch Blow Moulding
Implementing the HGY50-V3-EV into your production line offers distinct advantages of injection stretch blow moulding that go beyond simple container formation. These benefits directly impact profitability and product quality assurance.
1. Pristine Surface Quality
Because the preform is molded and blown in the same machine without being ejected into a storage bin, it never comes into contact with other preforms. This prevents the scuffing, scratching, and dust contamination common in two-step processes, ensuring a flawless surface finish.
2. Lightweighting Capabilities
The increased physical strength provided by biaxial stretching allows manufacturers to reduce the wall thickness of the bottle without compromising its top-load strength. This leads to significant savings in raw material costs—often the largest expense in bottle production.
3. Design Versatility
ISBM allows for the creation of non-round shapes (ovals, squares) and bottles with offset necks that are difficult to process in two-step machines. The precise control over material distribution also allows for complex aesthetic designs favored by K-Beauty brands.

Complementary Components
The injection stretch blow moulding machine relies on a carefully matched set of auxiliary components to maintain high-speed, reliable production. At the heart of the blowing process is a high-pressure oil-free air compressor that supplies clean, dry compressed air directly to the blow valves. This prevents moisture contamination in PET bottles and ensures consistent radial expansion during the stretch-blow phase. Korean plants typically pair the machine with our EP series rotary-screw compressors, which include integrated refrigerated dryers and filters to deliver air quality meeting ISO 8573-1 Class 1 standards.
Mechanical synchronization is achieved through precision roller chains, sprockets, and transmission shafts driven by the main servo motor. The rotary table uses a Yaskawa servo-driven Geneva mechanism or cam indexer linked by these chains and gears. This ensures exact 120° indexing between the four stations (injection, conditioning, stretch-blow, ejection) with positioning accuracy of ±0.05 mm. The transmission shafts are supported by NSK sealed bearings and lubricated via an automatic grease system, allowing 24/7 operation with minimal wear. All components are sized to match the 34.8 kW servo power of the main machine, delivering smooth acceleration and deceleration to keep cycle times stable at 12–18 seconds per shot.
