PRECISION AUTOMATION

Mechanical Arm Transfer & High-Pressure Blowing Station

The SW-F2 series runs fully unattended — mechanical arm transfer eliminates manual bottle handling, while the high-pressure blowing station ensures consistent shape at every cycle.

Automated Bottle Transfer

Servo-driven mechanical arm picks and places each bottle with ±0.1mm repeatability — no manual intervention required.

💨

High-Pressure Blowing

2.5–3.0 MPa blowing pressure with pre-blow + main blow two-stage control — consistent wall thickness on complex bottle profiles.

35,000–45,000 kg Clamping

Heavy-duty servo clamping unit locks the mold without flash or deformation — suitable for custom shaped and wide-body bottles.

CORE TECHNOLOGY

Built for Custom Bottles — Three Core Systems

Where most 2-cavity machines only handle standard round bottles, the SW-F2 series supports complex custom shapes — bear bottles, square, oval and non-standard profiles.

FAQ

2 Cavity PET Blow Molding Machine — Frequently Asked Questions

What is the output of a 2 cavity PET blow molding machine? ＋

The Sailwin SW-F2-650 and SW-F2-2000 both achieve 2,800 bottles per hour theoretical output. The SW-F2-650 handles bottles up to 650ml, while the SW-F2-2000 handles up to 1,800ml edible oil or condiment containers.

In contrast to semi-automatic machines, the 2 cavity fully automatic platform runs without manual preform loading — consequently reducing labour cost by 60–70% on the same shift.

Can a 2 cavity PET blow molding machine produce custom shaped bottles? ＋

Yes — this is a key advantage of the SW-F2 series. The machine supports custom bottle shapes including bear, cartoon, square, oval and non-standard profiles that standard machines cannot produce.

Sailwin manufactures a custom mold to match your bottle drawing, validates the sample in-factory, and ships the mold together with the machine. Furthermore, mold changeover takes under 30 minutes.

What is the minimum investment to start a PET bottle production line? ＋

The SW-F2-650 is Sailwin's lowest-cost entry into fully automatic PET blow molding. It includes full servo drive, Mitsubishi PLC control, and automatic preform loader compatibility — at significantly lower investment than 4 or 6 cavity machines.

In addition, the compact 2.8×1.9×2.2m footprint means it can be installed in small factory workshops without major renovation. Contact us for a factory-direct price.

What bottle sizes does the SW-F2 series support? ＋

The SW-F2-650 handles bottles up to 650ml (max height 260mm, max diameter 68mm, neck up to 38mm). The SW-F2-2000 handles up to 1,800ml (max height 330mm, max diameter 105mm, neck up to 45mm).

Both models support water, juice, personal care, edible oil and custom specialty bottles. Specifically, if your bottle is non-standard, send us the drawing and we will confirm compatibility.

Does the 2 cavity PET blow molding machine include an automatic preform loader? ＋

Yes. The SW-F2 series is compatible with an automatic embryo loader (2×1.2×2.7m). It continuously feeds preforms into the heating zone — enabling fully unattended 24-hour operation with one operator per shift.

The loader is available as an optional add-on. Furthermore, if you are planning a complete filling line, our team can advise on full turnkey configuration.

How much space does the SW-F2 series require? ＋

The SW-F2-650 requires only 2.8×1.9×2.2m floor space and weighs 2,000kg — one of the most compact fully automatic PET blow molding machines available. The SW-F2-2000 is slightly larger at 3.3×1.8×2.0m, weighing 2,500kg.

In addition, both models include the embryo loader (2×1.2×2.7m) as a separate unit — plan for a combined footprint of approximately 5×3m including loader and working clearance.

How long does mold changeover take on the SW-F2 series? ＋

Physical mold changeover takes approximately 30 minutes with one operator. The Mitsubishi PLC stores up to 50 bottle recipes — switching between saved recipes requires no mechanical re-adjustment.

Consequently, if you produce 2–5 bottle formats on the same machine, the SW-F2 is specifically designed to minimise changeover downtime between runs.

What certifications and warranty does the Sailwin SW-F2 include? ＋

All SW-F2 machines are CE certified and pass a full factory acceptance test before shipment. Each machine is run at full speed with your target bottle for final validation.

A 1-year full warranty is included with remote technical support via video call. In addition, spare parts are stocked in-factory and dispatched within 24 hours of request.
