A Practical Choice Between Manual and Fully Automatic
This semi-automatic blow molding machine fills the gap between manual blow molding and full automation. You load the preform by hand, and the machine handles the heating and blowing automatically. It is a solid option for factories that need flexibility without the high upfront cost of a fully automatic line.
If you are running small batch production, doing trial runs, or testing new PET bottle mold designs, this machine gets the job done without tying up too much capital. Many of our clients in Foshan and nearby areas use it for startup projects or seasonal product lines where demand fluctuates.
A Good Fit for Small Batch Production and Sampling
Fully automatic machines are great when you are running the same bottle day in and day out. But when you need to switch molds frequently or produce short runs, they can be overkill. This unit lets you change molds and adjust settings quickly, so you are not stuck waiting for a long changeover.
Bottle types you can work with include:
- PET preform mold-compatible bottles: water bottles, beverage bottles
- PET bottle mold-based designs: cosmetic bottles, wide-mouth jars
- Optional configurations: bottle volume, neck finish, wall thickness
Straightforward Operation, Low Entry Barrier
The machine runs on a PLC control system with a simple interface. You do not need a specialist to operate it. One worker can manage the loading while the machine cycles through heating and blowing. This keeps your labor costs reasonable and your training time short.
Note: The production rate is lower than a fully automatic blow molding machine, but the trade-off is flexibility and a much smaller footprint on your shop floor.
Optional Configurations
Rather than locking you into fixed specs, we build this machine around what you actually need. Typical options include:
- Cavity count: 1–4 cavities (optional configuration)
- Bottle volume: 100 ml–2 L (optional configuration)
- Bottle types: round, square, irregular shapes (optional configuration)
- Mold compatibility: standard or custom (optional configuration)
- Voltage: 220V/380V (optional configuration)
Tell us your target bottle size and production volume, and we will recommend the right setup.
Born Out of Mold-Making Experience
HEYANMOLD is based in Foshan, Guangdong, with years of hands-on work in PET preform mold and PET bottle mold manufacturing. We understand how the mold and the machine need to work together. When you buy a blow molding machine from us, you are not just getting hardware—you are getting a team that knows the full process from mold design to finished bottle.
Solid After-Sales Support
This is not a buy-and-forget purchase. We help with installation guidance, mold fitting checks, and basic troubleshooting. If you already have molds from another supplier, we can check compatibility before you commit.

Product Overview
HEYAN Technology offers semi-automatic PET blow molding machines as a suitable starting point for:
– Startup bottle manufacturers testing the market
– Small-batch production of custom or seasonal bottles
– Prototyping before committing to full automatic lines
– R&D labs developing new bottle designs
– Regions where labor costs favor semi-automation
These machines require an operator to manually place preforms into the heating and blowing stations, but produce bottles that meet typical commercial specifications at a fraction of the investment of fully automatic systems.

Semi-Automatic vs. Automatic: When to Start Here
| Scenario | Semi-Automatic | Automatic |
|---|---|---|
| Budget | Limited (< $10K machine investment) | Higher (> $30K+) |
| Volume | < 5,000 bottles/day | > 10,000 bottles/day |
| SKUs | Many, frequent changeovers | Few, stable recipes |
| Labor | Available and affordable | Expensive or scarce |
| Experience | New to blow molding | Established operation |
| Timeline | Need machine in 2 weeks | Can wait 4–6 weeks |
Advantages
- Low capital investment: Start production with minimal upfront cost
- Fast delivery: 10–15 days from order to shipment
- Training duration: Operator training typically completed in 1–2 days
- configurable per project: Change bottle design by simply changing the blow mold
- Quality validation: Produce market-ready bottles for customer approval before scaling up
- Upgrade path: Experience gained on semi-auto informs automatic line specification later
Typical Workflow
- Operator loads preforms into heating oven
- Preforms rotate through heating zones (temperature set per bottle design)
- Operator transfers heated preforms to blow mold station
- Machine stretches and blows preform into bottle shape
- Operator removes finished bottle
- Bottles are conveyed to leak test, labeling, or packing
Applications
- Startup water bottling plants
- Custom bottle prototyping for brand development
- Small-scale juice, dairy, and edible oil packaging
- Seasonal or promotional bottle runs
- Export-market testing before full line investment
- Educational and training facilities
FAQ
Q1. Who is this machine suitable for?
Startup bottle manufacturers testing the market, small-batch production of custom/seasonal bottles, prototyping before full automation, R&D labs, and regions where labor costs favor semi-automation.
Q2. What output can I expect?
Practical output is below about 5,000 bottles/day depending on operator and bottle size, with 1–8 cavities and bottle volume 100 ml–20 L.
Q3. How quickly can I start production?
Delivery is 10–15 days from order to shipment, and operator training is typically completed in 1–2 days.
Q4. Can I change bottle designs later?
Yes — change bottle design by simply changing the blow mold. This is a practical setup for many SKUs and frequent changeovers.
Q5. Does buying semi-auto prepare me for an automatic line later?
Yes. Experience gained on semi-auto informs the automatic line specification — output targets, cavity count, and automation scope — so the upgrade path is clearer.
Selection Guide
Three steps to a confirmed configuration:
- Budget and timeline: under about $10K and 2-week startup point to semi-automatic.
- Volume: below 5,000 bottles/day with many SKUs suits semi-auto; above 10,000/day points to automatic.
- Labor: if an operator is available and affordable, semi-auto keeps capital low while validating the market.
Delivery & After-Sales Support
- Order confirmation — bottle drawing, neck finish, and output target.
- Machine build with heating/zone settings per bottle design.
- Factory test with sample bottles before packing.
- Shipping and operator training (1–2 days).
- After-sales — mold changeover guidance and spare parts.
