PET products 56 PETplanet Insider Vol. 21 No. 10/20 www.petpla.net Chem-Trend showcases a preform coating system (PCS) for improved handling of PET preforms Chem-Trend partici- pated in the development of a new preform coating system (PCS). This system enables preforms to be accurately sprayed directly after the injection-moulding process. The solution was developed by Bonino Group in collaboration with Chem- Trend and Steidle. The system is installed directly after the injection-moulding machine and before the soft-drop or Octabin. It is designed to spray only the body of the preforms with extreme precision without applying any coating agent on the thread of the preforms. A specially designed “Safeguard” system installed around the neck area of the PET preforms prevents the coating agent from entering the preforms. The application method allows Lusin Lub O 32 F to coat preforms on the full body which results in a drastic reduc- tion of scratches during the filling and unloading of the Octabins. Bonino Group was able to engineer a portable unit that can be easily integrated into production lines. Using Bonino’s technol- ogy, preforms are diverted into the PCS system after production, where they are then properly oriented and individually coated. The unit can be adjusted to accommodate virtually all preform designs and sizes in a few minutes. The seamlessly integrated process integrated coating (PIC) system developed by Steidle can accurately dose micro quantities of Lusin Lub O 32 F and ensure that the entire body of each preform is uniformly coated. The preform coating system was developed for use with Lusin Lub O 32 F made by Chem-Trend. This food contact compli- ant coating agent is a hybrid product that combines the effects of a lubricant and release agent, it ensures uniform coating of all PET preforms. The system provides the following benefits to manufacturers of PET preforms and end customers:  A food contact compliant coating delivered by the integrated PCS safeguard that prevents Lusin Lub O 32 F from entering the body of PET preforms.  Low dosing rate of Lusin Lub O 32 F on PET preforms thanks to the improved efficiency of the coating process.  Reduces the number of scratched or scuffed PET performs.  Maximises the quantity of preforms per Octabin thus reducing shipping and warehousing cost. 10-15%more PET preforms to be packed inside the Octabin on average.  Improves bottle demoulding and bottle definition during the blow moulding process while not affecting the working life of heating lamps.  Eliminates bottle jamming in conveying lines. www.us.chemtrend.com Quiet, more compact and with frequency control Kaeser boosters with drive powers ranging from 22 to 45 kW are now available in a new design: as compact and space-saving complete units optimised for low vibration and noise emissions. The option of frequency control and many additional enhancements, such as optimised cooling, serve to reduce overall system and energy costs even further. Previously this size of booster was only available in conventional versions – without Sigma Frequency Control (SFC). The new drive function ensures harmonisation of the booster on the input side with the upstream compressor output. This allows for reduction of the relatively high switch- ing frequency characteristic of some booster applications. It’s precisely because applications do not always work with the same pressure that boosters must produce significantly greater pressure than is actually used in the application. The powerful SFC functionality helps adjust the free air delivery as consistently as possible to the needs of the system. This reduces switching differentials on both sides, as well as potentially resulting overpressure, leaks and machine load – all of which contribute to energy savings. Plug & run The new design saves space (the footprint has been reduced to just 2.3m² from 5m²) and makes maintenance more straightforward thanks to intelligent component layout. Despite their enhanced performance, the new boosters run noticeably quieter thanks to the enclosure with integrated after cooling as well as the low-vibration basic structure. For added convenience, the boosters are ready for immediate electrical connection upon delivery, minimising installation time and costs. Controller monitoring The integrated Sigma Control 2 controller is equipped with special booster software to ensure optimal system operation whilst also enabling convenient connection to master controller systems via Ethernet. Since all individual components can be perfectly coordinated with one another, the entire station can be optimised to provide maximum effi- ciency and performance. Integration is also possible within an Industry 4.0 environment. www.kaeser.de COMPRESSORS
