Blow Molding Machine

Krones S8

Blow Molding Machine Contiform – Overview


This used Krones Contiform S8 blow molding machine is engineered for high-efficiency production of PET bottles in modern beverage and industrial packaging operations. With a rotary configuration and robust mechanical design, it reaches up to 13,000 bottles per hour, supporting scalable output for medium to high-speed lines. The machine is optimized for PET containers and is suitable for diverse beverage production environments, including water, beer, wine, spirits, milk, oil, and carbonated soft drinks. Krones engineering ensures excellent reliability, consistent bottle quality, and streamlined changeovers.


Designed as a versatile component for a used bottling line or as a standalone blow molder, this second hand system delivers precise preform handling and stable heating, coupled with efficient blowing performance. It features an Alaska thread finish, an 8-cavity configuration, and a clockwise work direction, making it a proven choice for beverage production and industrial packaging where uptime and repeatability are critical.

Advanced Automation & Control Systems


The Contiform S8 integrates a Siemens PLC for robust automation and process control, complemented by a Krones HMI for intuitive operation and fast diagnostics. The control architecture supports stable preform heating profiles, accurate blowing cycles, and reliable handling of PET preforms and bottles. Safety interlocks and operator protections are integrated into the guarding and access points to support consistent production with minimized downtime.


Production Line Integration Capabilities


This blow molding machine can operate as a standalone unit or integrate seamlessly into a complete used bottling line. It interfaces effectively with upstream preform feeding systems and downstream air conveyors, rinsers, fillers, and labelers. Format changeovers are streamlined around the 8-cavity rotary platform, and the Alaska neck finish provides compatibility for a wide range of closures and filling monoblocks across beverage production.
