PET Bottle & Plastic
Blow Molding Machine
Manufacturer

The price of a PET blow molding machine varies by cavity count, automation level and bottle volume range. In general, a 2-cavity semi-automatic model starts at a lower investment, while a fully automatic 8-cavity high-speed machine represents a significantly higher capital expenditure.

However, the correct way to evaluate cost is total cost of ownership — including energy consumption, spare parts availability and output per hour. Contact us with your bottle specifications for a detailed factory-direct price quotation.

A PET blow molding machine (stretch blow molding) uses injection-moulded preforms that are reheated and biaxially stretched — producing clear, lightweight bottles ideal for water, CSD, juice and edible oil. In contrast, an extrusion blow molding machine melts plastic resin directly into a parison, making it suitable for HDPE jerrycans, drums, automotive tanks and industrial containers.

Specifically, PET machines excel at high-clarity thin-wall bottles; extrusion blow molding machines handle larger, more complex shapes in materials like HDPE, PP and PA. Sailwin manufactures both types.

Our 4-cavity automatic PET blow molding machine delivers 4,500–5,500 bottles per hour (BPH) depending on bottle volume. For small-format bottles (≤600ml) the output reaches 5,500 BPH; for standard bottles up to 1,800ml, output is 4,500 BPH.

Furthermore, our 6-cavity models achieve 7,500–12,000 BPH, and the 8-cavity high-speed model reaches 16,000 BPH — the highest output in our range.

Yes. All Sailwin blow molding machines — both PET stretch blow molding machines and HDPE extrusion blow molding machines — carry CE certification and are produced under ISO 9001:2015 quality management standards.

As a result, our machines can be imported and operated in EU member states, the UK, Australia and other markets that require CE or equivalent conformity. Full technical documentation is provided with every machine.

Standard plastic blow molding machine models are typically ready within 30–45 days after order confirmation and deposit receipt. Customised configurations, including OEM branding or non-standard bottle formats, may require 45–60 days.

Specifically, every machine completes a full-load factory acceptance test before packing. We provide video evidence of the FAT and can arrange third-party inspection on request.

Yes. Our blow molding machines support custom mold tooling for virtually any bottle shape. Send us your bottle drawing, sample or 3D file — our engineers will design and manufacture the mould in-house, ensuring it is fully compatible with the selected machine platform.

In addition, we support OEM machine branding, custom colour schemes and specific electrical standards (110V/220V/380V, 50Hz/60Hz) for different markets.

Yes. Sailwin provides on-site installation, commissioning and operator training at your factory. Our engineers have completed installations in over 60 countries across Asia, the Middle East, Africa, Europe and the Americas.

Furthermore, remote video-call support is available 24/7 for troubleshooting throughout the 2-year warranty period. Spare parts are stocked and shipped within 48 hours for common consumable items.

A fully automatic blow molding machine is recommended when your daily production target exceeds 8,000 bottles, labour costs are a major factor, or you require consistent output with minimal operator intervention. It integrates preform loading, heating and blowing in one continuous cycle.

In contrast, a semi-automatic blow molding machine suits start-up operations, small batch production, or factories that change bottle formats frequently. The lower initial investment makes it particularly popular for new market entrants. Our team can help you calculate the ROI for both options based on your targets.
