Stretch Blow Molding Machine Overview
A stretch blow molding machine is used to produce PET bottles by reheating preforms and blowing them into final bottle shapes inside precision molds. It is widely adopted in beverage, food, and packaging industries where consistent bottle quality and stable output are required.
LEKA stretch blow molding machines are engineered to balance output efficiency, energy consumption, and long-term production reliability—making them suitable for both new projects and production line upgrades.

Result: fewer interruptions and predictable daily output.
Consistent Bottle Quality
Controlled stretching and blowing process helps maintain uniform wall thickness and repeatable bottle geometry across cavities.
Result: reduced scrap rate and smoother downstream filling.
Energy-Efficient Operation
Heating and air usage are optimized to balance output performance with practical energy consumption in real factory conditions.
Result: lower operating cost per bottle.
Flexible Configuration Options
Cavity number, mold setup, and auxiliary integration can be configured based on bottle size, preform data, and target BPH.
Result: easier matching to real project requirements.
Factory-Friendly Layout
Compact layout allows smoother integration into existing production lines and simplifies maintenance access for routine service.
Result: reduced installation complexity and downtime.
Production Verification & Support
Machines can be validated through Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) to confirm output before and after installation.
Result: clearer expectations and lower project risk.
Customization & Project Support
A stretch blow molding project is not only about selecting a machine model. To deliver stable output and bottle quality, LEKA supports configuration matching based on your preform data, bottle design, target capacity, and factory utilities. The goal is to reduce project risk and avoid mismatched configurations.
What We Can Configure
- Cavities & molds: matched to bottle shape, neck finish, and target output.
- Heating setup: optimized for your preform weight and bottle performance requirements.
- Air & utilities plan: based on your factory power, compressed air, and space constraints.
- Line integration: support for downstream equipment planning (conveying, filling, labeling).
- Testing & verification: FAT / SAT guidance to validate performance and expectations.
If you are producing HDPE/PP containers (jerry cans, drums, chemical packaging), please refer to our Máquinas de moldagem por extrusão e sopro.
What to Send for a Fast Quotation
- Bottle application: water / CSD / edible oil / daily chemical / OEM
- Bottle volume: e.g., 330 ml / 500 ml / 1 L
- Preform data: weight (g) + neck finish (e.g., 28mm)

PERGUNTAS FREQUENTES
What materials can the two-stage PET stretch blow molding machine run?
What materials can the two-stage PET stretch blow molding machine run?
A: It is designed for PET preforms, including high-percentage food-grade rPET as long as the preforms meet your bottle specification. This process is not intended for HDPE/PP—those are typically produced by moldagem por extrusão e sopro or single-stage ISBM.
Can I customize bottle shapes, sizes, and neck finishes?
Yes. We support moldes personalizados for round, square, and complex panel designs with branding features. Typical volumes range from 200 ml to 2 L (larger formats on request). Standard necks include 28/30/38 mm, and custom threads per your closure spec are available.
What is the production speed?
Output depends on bottle size, number of cavities, and preform weight. With 2–8 cavities, the system can reach up to 16,000 BPH on small beverage formats while maintaining consistent quality.
How fast are changeovers between different SKUs?
Quick-connect utilities and saved recipes shorten mold and format changes to minutes. Operators can switch between sizes or neck finishes with guided HMI steps, minimizing downtime and scrap.
What utilities do I need (power, air, cooling)?
You will need electrical supply for oven and servo systems, high-pressure blow air (typically 30–40 bar), low-pressure plant air (6–8 bar), and process cooling via chiller for the oven and molds. A detailed utility list is provided with the quotation and site layout.
What about energy consumption?
High-efficiency IR lamps with smart zoning and blow-air recovery reduce kWh per bottle. Exact consumption is verified on your format during FAT/SAT so you have audited numbers for TCO and sustainability reporting.
Do you offer installation, training, and technical support?
Yes—turnkey support includes on-site installation and commissioning, operator training, and remote diagnostics. After-sales service covers hotline support, spare-parts supply, and optional preventive maintenance plans
What are the delivery times for the machine and molds?
Typical machine lead time is 60–90 days ex-works depending on configuration. Custom blow molds are usually 4–6 weeks after drawing approval. We can ship molds together with the machine to speed up start-up.
What is the warranty?
Standard warranty is 12 months from installation (or 18 months from shipment), covering core mechanical and electrical components. Extended warranty and spare-parts kits are available on request.
Can the machine handle lightweight bottles and high-rPET content?
Yes. Precise preform conditioning and stretch-ratio control support lightweight designs while keeping top-load strength. We can qualify high rPET percentages during sampling to ensure clarity, color, and cap integrity meet your standards.
