Used KRONES CONTIFORM 310 PRO blow molding machine, year 2020. Structure and production capacity. The used KRONES CONTIFORM 310 PRO blow molding machine, year 2020, operates with 10 rotating blow molding stations, specifically designed for the continuous production of PET containers. As a result, the machine delivers a maximum output of 18,000 bottles per hour, ensuring high productivity even during the most demanding operations. It efficiently processes 0.5-liter and 2-liter bottle formats, ensuring production flexibility. Preform heating and handling system. The system uses a type 06 heating module with a chain pitch of 36.4 mm, designed to process preforms with a neck ring diameter of up to 35 mm. As a result, it handles a wide range of packaging formats. Eleven heating elements increase the preform temperature, while motorized reflectors adjust its height to optimize energy use. Additionally, a dedicated forced-air cooling unit maintains temperature accuracy 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 blow molding stage during the pre-blow molding stage. The system then introduces an intermediate pressure level and channels the recovered air back into the process. As a result, it significantly reduces energy consumption, especially during high-volume operation. Neck Type and Preform Specifications KRONES configures the machine to handle preforms with a nominal neck diameter of 28 mm, based on drawing number 809908B171 for neck finishing. Specifically, the system supports preforms weighing 27.4 g, 38 g, and 46 g, all made of clear PET. Each format is optimized to achieve ideal stretch ratios depending on the final container geometry. Furthermore, KRONES ensures that each preform passes a rigorous dimensional check to ensure 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 orientor. Additionally, a simple tilter accommodates batches of carton-packed preforms with a maximum load capacity of 540 kg, thus ensuring constant and uninterrupted feeding. In particular, this layout minimizes manual intervention and increases overall reliability. Internal preform cleaning Before entering the heating module, the preforms pass through the PREJET LINEAR system, which removes internal dust and debris using 5 bar compressed air. As a result, this process ensures compliance with the hygiene protocols required in beverage packaging. In fact, KRONES has designed this feature to support applications where internal contamination could compromise quality or safety. Cooling System KRONES integrates a dedicated cooling unit within the machine to stabilize mold temperatures during the blow molding process. Additionally, the system cools the preform necks in the oven and blows air onto the container base after unloading to prevent deformation. It uses Pekasol L, a CFC-free coolant that meets current environmental regulations. As a result, the machine supports both efficiency and sustainability. Technical Overview The used KRONES CONTIFORM 310 PRO blow molding machine, model year 2020, offers a robust and energy-efficient solution for the high-speed production of PET containers. Thanks to integrated air recovery, precise temperature control, and modular preform management, the system meets the technical requirements of modern bottling lines. Furthermore, the machine ensures long-term reliability while reducing operating costs. Ultimately, KRONES offers a fully engineered platform that improves line productivity and meets evolving industry standards.
