They are the preferred equipment for the industrial production of various PET packaging containers.

Product Features

1.  High-efficiency forming Configuration  : With a 2-chamber design, the theoretical output can reach 2,200 to 2,700 pieces per hour, efficiently matching the demands of batch production and significantly enhancing the output efficiency per unit time.

2. Precise Heating System  : Equipped with 32 0.75KW smooth tubes, with a maximum heating power of 24KW, it features high heating efficiency and uniform temperature distribution, ensuring the stability of preform formation.

3. Dual pressure airway design  : The working air pressure is stably maintained at 7-9kg/cm², and the bottle blowing air pressure can reach 25-35kg/cm². The high and low pressure work in coordination to meet the requirements of different molding stages, ensuring that the bottle body is fully formed.

4. Rapid Cooling System : Equipped with a professional chilled water cooling device, the working air pressure is 5-6kg/cm², the temperature is constant at 10℃, and the flow rate of 30L/min ensures the rapid shaping of the bottle body, further enhancing production efficiency.

5. Compact Structure Design  : The equipment measures only 2.25m×1.6m×1.7m, weighs 2.5 tons, and has a compact volume that does not occupy space. It is suitable for various workshop layouts and saves installation space.

1. Intelligent control, easy to get started  : Equipped with a high-definition touch screen control system, the real-time operation status of the equipment is visually presented. The operation logic is clear and intuitive, and it can be quickly mastered without complex professional training, significantly reducing labor costs and operation error rates.

2. Quality benchmark, stable output  : A stable infrared heating system ensures uniform heating of the preform, and high-precision blow molding and clamping technology precisely controls the forming details. The finished bottles have high transparency, uniform wall thickness, and small dimensional errors, with quality consistency far exceeding the industry average.

3. Clean production, Compliance and Worry-free  : The fully enclosed production area isolates external dust and impurities, and the self-lubrication system prevents lubricating oil leakage and contamination of materials. It fully complies with the clean production standards of the food and pharmaceutical industries, ensuring product safety and compliance.

4.  Energy conservation and consumption reduction, cost control  : The optimized power system design results in an actual operating energy consumption of only 19KW, with electricity, gas and water consumption far lower than that of similar equipment. Long-term large-scale production can significantly reduce the overall production cost.

5.  Safe and practical, easy to maintain  : Equipped with multiple safety protection devices, the operation process is safe and reliable; The equipment has a scientific and reasonable structure layout, low noise, supports visual detection, and its core components are easy to disassemble and maintain, significantly reducing downtime for maintenance.

1.The equipment weighs 2.5 tons and measures 2.25m×1.6m×1.7m. During transportation, professional heavy-duty freight vehicles should be selected, equipped with customized fixed brackets to prevent damage to precision components due to shaking and collision during transportation.

2. The installation site should reserve sufficient space for operation and maintenance, ensure that the passageways around the equipment are unobstructed, and at the same time meet the equipment's requirements for power supply (the overall installed power is 27KW), air pressure (low pressure 1000L/min, high pressure 1500L/min), and chilled water (flow rate 30L/min).

3. It is recommended that professional technicians from the manufacturer carry out on-site installation and commissioning. Only after all parameters of the equipment are calibrated and meet the standards can it be put into formal production.

Maintenance and Upkeep

1.  Daily Maintenance  : Clean the surface of the equipment and the enclosed production area every day to remove dust and debris. Check the working condition of the infrared heating tubes and replace the aged or damaged ones in a timely manner. Check whether there is any leakage in the gas and water lines.

2. Regular maintenance : Check the self-lubrication system weekly, replenish the dedicated lubricating oil and ensure the oil passage is unobstructed to avoid dry grinding wear of components; Clean the impurities in the gas filter every month and replace the coolant in the chilled water system to prevent pipeline blockage and affect the cooling effect. Check every quarter whether the circuit connection is firm and clean the dust inside the control cabinet to avoid short-circuit faults.

3. Long-term Maintenance  : Conduct a comprehensive inspection every six months, with a focus on checking the operational status of core components such as the clamping mechanism, control system, and cylinders. Operate strictly in accordance with the maintenance manual provided by the manufacturer. Non-professionals are prohibited from disassembling core components without authorization to extend the service life of the equipment.
