(0.1L–20L) — Factory Direct

Q: What is the price of a semi automatic PET blow molding machine?

The price of a semi automatic PET blow molding machine from Sailwin ranges from approximately $4,500 to $28,000 FOB depending on the bottle capacity — from our entry-level SW-SEMI-2000 (0.1L–2L) to the large SW-SEMI-20L model. As a direct factory manufacturer established in 2008, we offer competitive pricing with no middleman markup. Contact us to receive a detailed quotation based on your required bottle size, output volume and any customizations needed.

Q: How many bottles per hour can a semi automatic PET machine produce?

Output depends on the model and bottle size. Our semi automatic PET blow molding machines range from 80 BPH (SW-SEMI-20L, large jugs) to 1,000 BPH (SW-SEMI-2000, small bottles). For example, the SW-SEMI-3L produces 400–800 bottles per hour for 3L water bottles. These figures are based on single-cavity operation with one operator; actual throughput may vary with preform quality and ambient temperature conditions.

Q: Can one person operate your semi automatic PET blow molding machine alone?

Yes — our semi automatic PET blow molding machine is specifically designed for 1-person operation. The operator manually loads preforms into the heating zone; the machine then handles heating, stretching, and high-pressure blow-forming automatically. Furthermore, the 5-inch PID touchscreen makes startup and parameter adjustment simple, allowing any worker with 30 minutes of training to run the machine independently on a full production shift.

Q: What is the minimum bottle size for your semi-automatic machine (0.1L)?

Yes, our SW-SEMI-2000 model supports bottles as small as 100ml (0.1L) — suitable for cosmetic toners, sample vials, medicine bottles and miniature condiment containers. The minimum neck diameter supported is 28mm. For very small-volume bottles, we recommend confirming preform specifications with our engineering team to ensure compatibility with the heating zone configuration.

Q: How long does mold change take on a semi automatic PET blow molding machine?

Mold change on our semi automatic PET blow molding machines takes under 30 minutes with a standard wrench — no crane or specialist technician required. The process involves loosening 4 bolts, sliding out the old mold, installing the new mold, and loading a saved bottle recipe on the touchscreen. This quick-change design makes our machines ideal for factories producing multiple bottle SKUs or running short production runs with frequent size changes.

Q: What is the difference between a cheap semi automatic PET machine and a fully automatic?

A cheap semi automatic PET blow molding machine requires one operator to manually load preforms; output ranges from 80 to 2,000 BPH. A fully automatic machine uses an automatic preform loader and conveyor system, achieving 2,800 to 16,000 BPH with no operator intervention. Semi-automatic models have lower initial investment, smaller footprint, and can produce bottles up to 20L — while fully automatic machines are best for high-volume mass production of standard water or beverage bottles below 2L.

Q: Can your manual PET bottle blowing machine produce 20L water jugs?

Yes — our SW-SEMI-20L model is specifically designed to blow 10L and 20L PET/PC water dispensing jugs, with a maximum neck diameter of 90mm. This is a unique capability of the manual PET bottle blowing machine that fully automatic machines cannot match, as automatic models are limited to standard bottle sizes below 2L. The SW-SEMI-20L produces 80–200 jugs per hour and is popular with regional bottled water companies and office water cooler suppliers.

Q: What certifications does your semi automatic PET blow molding machine carry?

All Sailwin semi automatic PET blow molding machines carry CE certification (EU Machinery Directive 2006/42/EC) and are manufactured under ISO 9001:2015 quality management system. CE certification confirms compliance with European electrical safety and mechanical safety standards. In addition, we provide full technical documentation including wiring diagrams, operation manual, spare parts list and a one-year factory warranty on every machine.

The ideal low-cost manual PET blow molding machine for startups, small bottle factories, and product sampling — minimal footprint, zero complex automation required.

EASE OF OPERATION

Easy 1-Person Operation & Under 30-Minute Mold Change

Many startups fear complex machinery — skilled technicians are hard to hire and retain. Our semi automatic PET blow molding machine is engineered so that any worker with 30 minutes of training can operate it alone.

How to Operate a Manual PET Blow Molding Machine — 3 Steps

Load the PET Preform

Place the PET preform onto the mandrel by hand. The infrared oven heats it automatically to the set temperature. No conveyor or auto-loader required.

Press Start — Machine Does the Rest

The mold closes, the stretch rod extends, and high-pressure air (2.5–4.0 MPa) expands the preform to the bottle shape. The full blow cycle completes in 3–8 seconds per bottle.

Remove the Finished Bottle

Mold opens and the operator removes the finished PET bottle. Ready for the next preform immediately. No cooling delay, no trimming required.
