Stretch blow molding machine YG series

for PETfor plastic bottlesfor bottles

Product overview
The YG Machinery Automatic PET Bottle Blowing Machine is a high-automation stretch blow molding system that transforms PET preforms into finished bottles for beverage, edible oil, daily chemical and pharmaceutical packaging. It is offered in multiple configurations from hand-inserted semi-automatic units to fully automatic multi-cavity lines, designed to deliver high output, stable quality and improved energy efficiency.

Key selling points

• Full servo system: full servo drive for high precision, faster cycle times and energy savings (25%–30% vs older hydraulic systems).
• Intelligent control: advanced PLC and touchscreen with real-time OEE dashboard for monitoring and diagnostics.
• Fast mold changeover: quick-lock mold change system to reduce downtime and increase flexibility.
• Uniform preform heating: infrared conveyorized heater with self-rotation system to ensure even heating and consistent wall thickness.

Hand-inserted (semi-automatic) model description
The hand-inserted preform machine requires manual placement of the mold/preform into the blow molding system while other steps are automated; available in one-chamber and two-chamber variants.

Core technical advantages

• Stretch blow molding technology delivering good clarity, strength and lightweight bottles.
• Air recovery features and servo control reduce energy consumption and operating costs.
• Fully automatic lines can perform automatic loading, preheating, blowing and discharge.
• Designed for high OEE and robust long-term operation in high-demand production environments.

FAQ (selected)

• What factors should I consider when buying? Production capacity (bottles/hour), bottle-type flexibility and service/support capabilities matter most; machines range from compact 2-cavity to high-capacity multi-cavity units.
• How to maximize energy efficiency? Use full servo-drive systems and air recovery features to reduce energy waste compared with hydraulic systems.
• What causes inconsistent bottle quality? Incorrect preform heating or blowing pressure; precise adjustment via intelligent control and uniform preform heating prevents defects.

Applications

• Beverage industry: bottled water, soft drinks, juices.
• Edible oil and condiments: cooking oil, sauces.
• Daily chemical: shampoos, detergents, cosmetics.
• Pharmaceutical and nutraceutical liquid containers.

After-sales and service notes (product-related only)

• Pre-sale consultation typically covers factory layout and capacity planning for the selected model.
• After-sales support includes technical assistance, remote diagnostics and spare part supply plans to reduce downtime.
