Frequently Asked Questions (FAQs)
What is the average lead time for a semi-automatic PET blow molding machine and custom molds?
As a leading semi automatic pet blow molding machine manufacturer, we keep our production agile. For standard machine configurations, our typical factory turnaround is 20 to 30 days. If you require custom stretch blow molding tooling or specialized bottle designs, the engineering and testing process adds about 10 to 15 days.
Can this machine handle both small 330ml water bottles and large 5L oil bottles?
Our standard pet bottle blowing machine series is highly versatile, but physical mold pocket sizes dictate total range.
- Standard Series: Optimized for 200ml to 2L containers (perfect for a standard mineral water bottling plant).
- Large Capacity Series: Engineered specifically as a 5 gallon bottle blowing machine or a 5L oil bottle blower with heavy-duty clamping mechanisms.
To run both sizes efficiently, we recommend a two-machine setup to avoid frequent, time-consuming mold swaps and mechanical adjustments.
What are the total infrastructure requirements for setting up this equipment?
Operating a semi automatic pet blow molding machine factory setup requires three core utility inputs.
| Utility Type | Requirement Level | Primary Function |
|---|---|---|
| Electricity | 220V/380V/440V (3-Phase, 50/60Hz) | Powers the pet preform heating oven and plc control system |
| High-Pressure Air | 2.0 - 3.0 MPa (20 - 30 Bar) | Supplies the force for stretch blow molding |
| Low-Pressure Air | 0.8 - 1.0 MPa (8 - 10 Bar) | Drives pneumatic valves and cylinder actuations |
| Cooling Water | 15°C - 20°C Chilled Water | Circulates via an industrial cooling chiller to cool the mold plates |
Do you supply the PET preforms and caps along with the machinery?
We are a dedicated semi automatic pet blow molding machine supplier and machinery manufacturer, focusing entirely on hardware excellence. While we do not manufacture plastic consumables ourselves, we ship out custom preform samples during our Factory Acceptance Testing (FAT) phase. We also maintain partnerships with top US and global preform wholesalers to connect you with high-quality, cost-effective raw materials for your plastic container manufacturing business.
