The Semi-Automatic 5 Gallon / 20 L PET Bottle Blow Molding Machine (Model ESS-5G) is specially designed for producing large-volume PET containers such as 3 Gallon and 5 Gallon water jugs, edible oil bottles, and household storage jars.
It offers an ideal balance between investment cost and production efficiency for small-to-medium water-bottling factories.
Using advanced infrared preform heating and a servo-driven clamping system, the machine ensures uniform wall thickness, high transparency, and stable output up to 90 BPH (bottles per hour).
Its compact structure, simple operation, and low energy consumption make it an excellent choice for businesses upgrading from manual or outdated semi-automatic models.
Dedicated for 5-Gallon / 20 L PET Bottles: Specially designed for producing large-volume water-dispenser bottles (3–5 gallon, 10–20 L) with consistent wall thickness and high transparency.
High Output, Stable Operation: Achieves up to 90 bottles per hour with dual-cavity semi-automatic configuration—ideal for small and medium-scale bottled-water factories.
Servo-Driven Clamping System: Provides precise mold closing and consistent blowing pressure, improving product uniformity and reducing defect rate.
Intelligent Heating Control: Equipped with an independent infrared heating oven; each lamp can be adjusted separately to ensure uniform preform temperature and save up to 30 % energy.
Human–Machine Interface (HMI): Simple touch-screen control with fault alarm and parameter memory; operators can easily switch between bottle sizes.
Compact Footprint & Easy Maintenance: Modular design simplifies installation and daily cleaning, suitable for factories with limited floor space.
Safety & Compliance: Full CE-standard safety door interlocks and emergency-stop system guarantee reliable operation.

Lower Investment, High Profitability: Ideal alternative to fully automatic lines—minimal labor (only 1–2 operators) and rapid ROI within 6–12 months.
Flexible Production: Quick mold change (< 15 min) allows producing multiple bottle sizes (10 L, 15 L, 18.9 L, 20 L) on one machine.
Energy-Efficient: Optimized heating and air-recycling system reduce total power consumption by 20–30 % compared with conventional semi-auto models.
Reliable Performance: Core components (air valves, cylinders, sensors) sourced from international brands ensure long-term stability.
Easy Operation & Training: Operators can master machine setup in 1 day; multilingual interface available (English, Spanish, Russian, Arabic, Chinese).
After-Sales Support: Includes on-site commissioning, 1-year warranty, lifetime technical support, and spare-parts availability.
Customizable Solutions: Optional configurations for 110 V/220 V/380 V power supply, different bottle necks, and mold sizes.
Proven Worldwide: Over 200 units installed in Asia, Africa, and Latin America, trusted by leading bottled-water producers.
(1) Air compressor is the air source for PET stretch blow molding machine, carrying out the process of compressing air from atmosphere to the required pressure.
(2) Air dryer is to remove the moisture from the compressed air and lower temperature of the compressed air in the heat exchanger.
(3) Air filter is to clear up the impurities out of the compressed air, like carbon-hydrogen, tiny dust and solid particles.
(4) Air tank is to receive and supply air for the machine as storage.
