Used blow molding machine KRONES CONTIFORM 310 PRO year 2020 Structure
and Production Capacity The Used blow molding machine KRONES CONTIFORM
310 PRO year 2020 operates with 10 rotary blowing stations,
specifically engineered for the continuous production of PET
containers. Consequently, the machine delivers a maximum output of
18000 bottles per hour, providing high throughput even during
demanding operations. It efficiently processes bottle formats of both
0.5 liters and 2 liters, ensuring flexibility in production. Heating
System and Preform Handling The system uses a type 06 heating module
with a 36.4 mm chain pitch, designed to process preforms with neck
ring diameters up to 35 mm. As a result, it handles a wide range of
packaging formats. Eleven heating elements raise the preform
temperature, while motorized reflectors adjust their height to
optimize energy use. Moreover, a dedicated forced-air cooling unit
maintains temperature precision within plus or minus 2 degrees Celsius
throughout the process. Compressed Air Recovery System KRONES equips
the machine with the Air Wizard Pro system, which reuses compressed
air from the final blowing stage during the pre-blowing phase.
Therefore, the system introduces an intermediate pressure level and
channels the recovered air back into the process. Consequently, it
significantly reduces energy consumption, especially during
high-volume operation. Neck Type and Preform Specifications KRONES
configures the machine to handle preforms with a 28 mm nominal neck
diameter, based on the neck finish drawing number 809908B171.
Specifically, the system supports preforms weighing 27.4 g, 38 g, and
46 g, all in transparent PET. Each format is optimized for ideal
stretching ratios depending on the final container geometry.
Furthermore, KRONES ensures that each preform passes strict
dimensional verification to guarantee compatibility. Preform Feeding
and Orientation System The CONTIFEED RS unit manages preform loading
through a combination of silo, elevator, enclosed conveyor, and 2500
mm roller orienter. In addition, a simple tipper accommodates
carton-packed preform batches with a maximum load capacity of 540 kg,
thus ensuring consistent and uninterrupted feed. Notably, this layout
minimizes manual intervention and increases overall reliability.
Internal Preform Cleaning Before entering the heating module, preforms
pass through the PREJET LINEAR system, which removes internal dust and
debris using compressed air at 5 bar. As a result, this process
ensures compliance with hygiene protocols required in beverage
U6254234 packaging. In fact, KRONES designed this feature to support
applications where internal contamination could compromise quality or
safety. Cooling System KRONES integrates a dedicated cooling unit
inside the machine to stabilize mould temperatures during the blowing
phase. Additionally, the system cools the preform necks in the oven
and blows air on the container base after discharge to prevent
deformation. It uses Pekasol L, a CFC-free refrigerant fluid that
meets current environmental regulations. Consequently, the machine
supports both efficiency and sustainability. Technical Summary The
Used blow molding machine KRONES CONTIFORM 310 PRO year 2020 offers a
robust and energy-efficient solution for high-speed PET container
production. With its integrated air recovery, precise thermal control,
and modular preform management, the system meets the technical demands
of modern bottling lines. Furthermore, the machine ensures long-term
reliability while reducing operating costs. Ultimately, KRONES
delivers a fully engineered platform that enhances line productivity
and meets evolving industry standards.
